[android-developers] ArrayList[0] through ArrayList[n-1] element being overwritten by ArrayList[n]

[Jeff Biss]

Somehow the name in the first ArrayList position (see Line 6) was 
overwritten with that in the second (see Line 13). Can anyone offer a 
reason as to what might be happening?

Refer to LogCat section for the numbers:

- Lines 2 and 3 show that the cursor has accessed the DB.

- Lines 4 thru 9 show that the names are retrieved from the DB and passed 
to ArrayLists.

- Lines 10 through 14 show the petNameList contents (see A) passed to the 
adapter (see B).

- Lines 15 through 18 show petNameList contents passed from MainActivity 
(see C).

- Lines 22 through 27 show that the first position of the ArrayList holds 
"qwerty".

- Lines 31 through 36 show that the second position of the ArrayList holds 
"qwerty".

I will keep experimenting to see if I can find out what happens and post it 
if I find the reason.

**LogCat:**

1. !--MainActivity: Starts here-!
2. DB has: 2 rows
3. cursor has: 2 rows
4. The following should be the same:  
5. name from cursor is: fert
6. petNameList[0] is: fert
7. The following should be the same:  
8. name from cursor is: qwerty
9. petNameList[1] is: qwerty
10. petNameList is: [com.example.jbiss.petminder.PetName@ea7cc11,

25. pNm (String ) is: qwerty
26. NOTE: item should equal mItems[0]
27. onBindViewHolder passed: item.getPetName() qwerty to ViewHolder

**The relevant code in MainActivity:**

Log.d("!--MainActivity", "Starts here-!");

long numItems = mDbHelper.getPetCount();
Log.d("DB has", String.valueOf(numItems) + " rows");
if (numItems != 0) {
cursor = mDbHelper.getPetNames();
numItems = cursor.getCount();
Log.d("cursor has", String.valueOf(numItems) + " rows");
cursor.moveToFirst();

A)

for (int i = 0; i < numItems; i++) {
PetName name = new PetName(cursor.getString(PET_NAMES));
Log.d("The following should be the same", " ");
Log.d("name from cursor is", name.getPetName());
petNameList.add(name);
//the following is for troubleshooting, it gets the 
currently added petname
PN = petNameList.get(i);
pName = PN.getPetName();
Log.d("petNameList[" + i + "] is", pName);
cursor.moveToNext();
}
} else{
//otherwise, if no pet names exist int he DB, make the no pets 
found message visible
msgTv.setText(R.string.no_pets);
msgTv.setVisibility(View.VISIBLE);
}

B)

Log.d("petNameList is", String.valueOf(petNameList));
num = petNameList.size();
Log.d("petNameList count is", String.valueOf(num));
Log.d("petNameList elements passed to mAdapter", " ");
for(int j =0; j < num; j++){
PN = petNameList.get(j);
pName = PN.getPetName();
Log.d("petNameList[" + j + "] passed to the adapter constructor 
is", pName);
}
//setup the adapter and apply it to the RecyclerView
mAdapter = new SelectNameAdapter(this, petNameList);
mRecyclerView.setAdapter(mAdapter);


**Adapter code:**

private ArrayList mItems;
private Context mContext;

public SelectNameAdapter(Context context, ArrayList items) {
Log.d("made it to", "SelectNameAdapter constructor");
Log.d("items is", String.valueOf(items));
PetName PN;
String name;

C)

[android-developers] Why is only the last item in an ArrayList shown in RecyclerView?

[Jeff Biss]

I am trying to learn how to use the RecyclerView and have found that only 
the last item in an ArrayList are displayed in both positions (there are 
only two) and can't figure out why. I have used LogCat to show what is 
going on so look to the LogCat output below.

- Lines 2 and 3 show that the cursor has accessed the DB.

- Lines 4 thru 7 show that the names are retrieved from the DB and passed 
to ArrayLists.

- Lines 8 and 10 show that the ArrayList petNameList is succefully passed 
to the adapter (as items).

- Line 17 shows what position in the ArrayList is being pointed to

- Line 18 shows what is stored in ArrayList[0] and line 19 shows what is 
now in "item". (I assume that what is shown is a pointer).

- Line 20 states that the values in lines 18 and 19 should be the same name 
and they are.

- Line 21 shows what onBindViewHolder has passed to the ViewHolder and it 
is NOT the first name stored in the DB or in the
  ArrayList. It should be "fert" (see line 5).

- Line 26 shows what is stored in ArrayList[1] and line 27 shows what is 
now in "item". (I assume that what is shown is a pointer).

- Line 28 states that the values in lines 26 and 27 should be the same name 
and they are.

- Line 29 shows what onBindViewHolder has passed to the ViewHolder and it 
is the name stored in the DB and in the
  ArrayList.

So, it appears that my "setText statement is passing an incorrect value, 
"qwerty", to the ViewHolder is wrong and I currently do not know why. I am 
researching this and will post an answer if I find it before someone ansers 
this question.

For clarity and space, I copied only what I think is the relevant 
MainActivity code below the LogCat output and the Adapter code below that. 
Each shows the Log.d() statements that should help with correlation.

**LogCat:**

1. !--MainActivity: Starts here-!
2. DB has: 2 rows
3. cursor has: 2 rows
4. name from cursor is: fert
5. pN arraylist[0] is: fert

[android-developers] Re: things BSP - open source?

[Jeff Thompson]

Yes, this is, indeed, exciting. However, only 3, low-performance, devkits 
are supported right now. This has got to change to where anyone can develop 
a BSP for their peculiar hardware, and soon. Until then, Things will just 
be an amusing little toy. I've got clients wanting this NOW.

[android-developers] ERR_UNKNOWN_URL_SCHEME after APK download

[Jeff]

Hello,

I'm trying to install an APk right after the download is completed. The APk 
gets open with the browser and throws ERR_UNKNOWN_URL_SCHEME. I'm assuming the 
the device thinks the downloaded file needs to be open with the browser instead 
of the android application installer.

[android-developers] Re: Google Play Services adds nearly 10,000 methods!

[Jeff Campbell]

The latest version and the Google Play Services (4.3) now adds about 2,500 
more methods (since 4.2)!!  (Adding Google Play Services to your project 
will add about 14,000 methods to your app) seems to be getting worse 
and worse!

On Friday, February 7, 2014 2:14:50 PM UTC-7, Jeff Campbell wrote:

 We have an app that depends on a lot of libraries, and recently we wanted 
 to integrate Google Maps into our application.  We learned that we would 
 have to add the following dependency to our app:

 compile 'com.google.android.gms:play-services:4.1.32'

 Before adding this dependeny, our app had about a 40k method count.  After 
 adding this dependency our method count jumped to about 50k (about 10k 
 methods added to our apk!).  And, it seems that with every new version of 
 this dependency it grows more and more (we noticed about a 2k growth in the 
 last update).

 I know that this dependency contains a LOT of different types of services 
 which include things we don't even use (which all contribute to the 10k 
 method count).  I know that I can use Proguard to strip out un-needed 
 methods, but in a development environment this just slows down build time, 
 and can make debugging issues difficult.

 Could the Google Play Services be divided into seperate aar projects? 
  Example:

 play-services-core (required by all... assuming that there is some shared 
 code)
 play-services-maps
 play-services-games
 play-services-ads
 play-services-plus
 play-services-wallet
 etc

 Doing this would reduce the risk of apps hitting the 65k method limit cap 
 (seems crazy that a Google library takes 15% of the 65k limit of any single 
 app)

 Thanks,
 Jeff

[android-developers] Google Play Services adds nearly 10,000 methods!

[Jeff Campbell]

We have an app that depends on a lot of libraries, and recently we wanted 
to integrate Google Maps into our application.  We learned that we would 
have to add the following dependency to our app:

compile 'com.google.android.gms:play-services:4.1.32'

Before adding this dependeny, our app had about a 40k method count.  After 
adding this dependency our method count jumped to about 50k (about 10k 
methods added to our apk!).  And, it seems that with every new version of 
this dependency it grows more and more (we noticed about a 2k growth in the 
last update).

I know that this dependency contains a LOT of different types of services 
which include things we don't even use (which all contribute to the 10k 
method count).  I know that I can use Proguard to strip out un-needed 
methods, but in a development environment this just slows down build time, 
and can make debugging issues difficult.

Could the Google Play Services be divided into seperate aar projects? 
 Example:

play-services-core (required by all... assuming that there is some shared 
code)
play-services-maps
play-services-games
play-services-ads
play-services-plus
play-services-wallet
etc

Doing this would reduce the risk of apps hitting the 65k method limit cap 
(seems crazy that a Google library takes 15% of the 65k limit of any single 
app)

Thanks,
Jeff

Re: [android-developers] Using ACTION_OPEN_DOCUMENT for editing files

[Jeff Sharkey]

Yep, you're right that checking FLAG_SUPPORTS_WRITE is the best way to
check if a write is allowed.

If you're really looking to focus on writing data, then
ACTION_CREATE_DOCUMENT might be a better fit, since it also lets the user
select an existing file, and it filters to only allow selection of
documents that have FLAG_SUPPORTS_WRITE set.

I'm thinking that allowing an app to request filtering of read-only
documents during a OPEN_DOCUMENT request would lead to user confusion
because of the inconsistency between apps.  (For example, a user would
still expect to open a read-only document for viewing purposes.)  If a user
then tried saving changes to a read-only document, it makes sense for the
app to use CREATE_DOCUMENT to ask them to save the modifications somewhere
else.

Hope this helps.  :)

 As far as I can tell from the documentation and testing with the new
 Storage Access Framework and Intent.ACTION_OPEN_DOCUMENT, there doesn't
 seem to be a way (via an extra or otherwise) to pass with the Intent
 request to open a document to only return documents from providers that
 support writing (i.e. have FLAG_SUPPORTS_WRITE set).  Instead, we are
 forced to check a document selection made by the user (via a metadata
 query) to determine if the document supports write before we attempt to
 open an OutputStream or ParcelFileDescriptor in w mode.  Is this correct,
 or have I overlooked something?

 This seems to be a large missing piece in the new Storage Access Framework
 when attempting to allow a user to open an existing document to be edited
 as it forces the user to make a selection first, then have us check if they
 can write, throw and error if they cannot, and force them to pick again.
  Furthermore, we cannot say that it is uncommon for documents providers not
 to support writing, because even the system media documents provider (i.e.
 the source for images/videos) does not support write and will throw and
 IllegalArgumentException (Media is read-only) when one attempts to write
 to one of its files (as an image editing app, the most common example used
 in the docs, would attempt to do).  Is there a proper method with the new
 SAF of limiting selections to writable providers only?

 Feedback appreciated for anything I may have missed here.  As it stands,
 suggesting that developers use ACTION_OPEN_DOCUMENT for in-place editing
 doesn't seem like a viable approach.

Re: [android-developers] Re: MediaPlayer suddenly stopped working in Android 4.2

[Jeff Sharkey]

Starting in Android 4.2, processes may have different views of the
filesystem depending on which user they're running as.  For example,
/sdcard/foo.mp3 could refer to different files for different users.

To correctly disambiguate filesystem paths, you'll need to open the
file in your app process and pass the FileDescriptor to the
mediaserver (which is shared between all users on a device).
Something like this should work:

MediaPlayer player;
FileInputStream fis = new FileInputStream(myFile);
try {
player.setDataSource(fis.getFD());
} finally {
fis.close();
}

It sounds like the setDataSource(String path) method needs to be
fixed; tracking in 7962739.

[android-developers] Tomcat creating new HTTP jsessionid for each page on Android browser for Android versions 3.x and lower after switching from HTTPS to HTTP

[jeff]

Platform: Windows 2008 R2  
Web Servers: IIS 7.5, Tomcat 5.5


I have a JSP website which uses login-form authentication, via a custom 
servlet.  Below is the order of how login proceeds:

Login (SSL) - Auth (SSL) - Intermediary Page 1 (SSL) - Intermediary Page 
2 (non-SSL) - Intermediary Page 3 (non-SSL) - Homepage (non-SSL).

Now, this process works just fine in all major desktop browsers, iOS, and 
Android 4.x.  However, **I am experiencing problems with Android 3.x and 
lower.  When I switch over from HTTPS to HTTP, Tomcat creates a new HTTP 
jsessionid for each page.**

Why is this a problem?  Because the HTTP session variables are lost when 
simply navigating to another HTTP page.  It seems that swtiching from HTTPS 
to HTTP causes Tomcat to keep creating a new HTTP session for these older 
versions of Android.

I tried passing jsessionid in the url from Intermediary Page 2 to 
Intermediary Page 3, which works as long as I do it for every single page 
the user accesses thereafter and that's simply not going to cut it, since 
there are many, many, many JSP pages this website manages.  In other words, 
I have to pass the jsession via URL to the Homepage, in order to maintain 
the HTTP session.

I don't know what to do, honestly.  I don't understand why Tomcat is 
creating new HTTP sessions and thus losing any and all session variables 
which were set previously in HTTP space.

Let me clarify that I'm not talking about maintaining sessions from HTTPS 
to HTTP.  The problem here is AFTER the user is redirected to HTTP space, 
where Tomcat creates new sessions for each and every page accessed in HTTP 
space, instead of maintaining the one HTTP session.

Does anyone have any solutions, as to why Android 3.x and lower are 
affected and how to resolve it?  Has anyone ever had this problem with the 
older Android versions?

Thank you.

**UPDATE**

I have confirmed that the request Header, Connection:keep-alive, does NOT 
appear for Android 3.x and lower.  This may be the reason why Tomcat is 
destroying and creating a new JSESSIONID.  But the problem is IIS 7.5 has 
connection:keep-alive enabled, although I think that's specifically for the 
response Header.  And, besides, Connection:keep-alive appears for all the 
other platforms and browsers that work.  So, for whatever reason, Android 
3.x and lower doesn't support Connection:keep-alive or there's an issue 
with how IIS 7.5 and Tomcat 5.5.  I'm just not sure.

[android-developers] Error replacing two fragments with scrollviews

[Jeff Tycz]

I have 2 fragments and both have`Scrollviews in them, I make a selection 
from a ListView and that replaces the first fragment with the other 
fragment that has the scrollview. 

The problem is that when I try to replace the fragment with the new one I 
get an error saying ScrollView can only contain one direct child which it 
does, it has one RelativeLayout which holds all the content.

If i take the ScrollView out of the first fragments view I do not get the 
error and the fragment gets replaced fine but I need the scrollview in the 
first fragment.

What is causing this issue, does replacing a fragment not remove the view 
fully?

Re: [android-developers] Tabbed Menu with Gallery-like Menu in one of the tab

[Jeff Huang]

the problem should be coming from.

public void setViewImage(ImageView v, String value) {
super.setViewImage(v, value);
try {
v.setImageBitmap(BitmapFactory.decodeStream(new

} catch (Exception e) {

[android-developers] Android app using webview causing The page cannot be displayed because an internal server error has occurred(Win/Tomcat)

[jeff]

We have an android app using webview to display a page called
login.jsp.  This same page authenticates a user, via a servlet, and
forwards them to another page called index.jsp.  It is in the
index.jsp page where we get an error message that reads:

The page cannot be displayed because an internal server error has
occurred

(We are running Windows 2008 R2 Standard SP1/Apache Tomcat 5.5.28, by
the way.)

I browsed the Tomcat log files and the error is:

java.lang.ClassCastException: java.lang.Object cannot be cast to
java.lang.String...

Now, before I post any code, we pinpointed the problem to a
proprietary Java method being called inside the index.jsp page.  The
method is part of a closed-source class provided by a third-party
vendor.  That is, it is a black-box to us; we don't have the source
code, and it is provided to us by a third-party vendor (who is of no
help, because the class was not explicitly designed for mobile
platforms).

Here's the weird thing: The index.jsp page works on desktop browsers
and mobile browsers (i.e. Android, Safari), in both emulators and the
device.  The error above ONLY occurs when launched from the app.  We
confirmed it fails with Android version 2.3.6, 2.3.7, and 4.x on
emulators and devices; however, it does work on Android SDK Emulator
2.3.3.

I'm not asking to diagnose why the class is failing because, frankly,
I think that might be a dead-end, unless someone here is familiar with
BMC Remedy.  I'd rather not waste anybody's time.

But what I am asking is why on Earth would a paged served by Apache
Tomcat get an error in an android app webview, yet it works in the
browser?  It's not just that the error occurs in the app that doesn't
make sense.  What's bizarre is there's an error in the first place.
webview is just an extenion of the webkit engine and behaves as a
browser -- it's a client.  So, the app is the client.  And the jsp
code is parsed by Tomcat and the request is sent to the app's webview,
which would parse the html, right??? Or, am I completely wrong on the
model?

Maybe someone can explain how webview works under the covers?  Does
webview act as a true client?  Why would it cause Tomcat to throw an
error.  webview shouldn't have any business processing jsp code --
isn't that Tomcat's responsibility?  I would love to hear an
explanation on the full process of how webview works, because it seems
like it's not a true client-model relationship inside the app.

Thank you.

[android-developers] Connect MediaRecorder to MediaPlayer

I want to test running both the hardware video encoder and decoder 
simultaneously. To that end I'm trying to figure out how to connect the 
output of a MediaRecorder as the input to a MediaPlayer. The only way I 
could figure out to do this was through DatagramSockets connected through 
the loopback and ParcelFileDescriptors. I'm having some trouble getting 
this to work though. Is there a better way to hook up a MediaRecorder to a 
MediaPlayer? Know of any sample code that exists?

[android-developers] Re: able to select 2 RadioButton in a RadioGroup ??!??!

[Jeff]

I know Im too late to reply to this, but for anyone who comes through here 
looking for a solution...

You must register an id for each RadioButton in the RadioGroup. The 
RadioGroup will clear RadioButton selection based on their resource id.


RadioGroup group = new RadioGroup(this.
getApplicationContext()); 
this.setContentView(group); 

for (int i = 0; i  10; i++) { 
group.addView(getRadioButton(i)); 
} 


private RadioButton getRadioButton(final int position) { 
RadioButton v = new RadioButton(this.getApplicationContext()); 
*int i = 0;*
if (position == 0) { 
v.setChecked(true); 
*v.setId(i++);*
} 

return v; 
}

[android-developers] Re: How to implement multiple Android versions to use different libraries?

[Jeff A Knaggs]

Similar to Kostya's suggestion, but requires less knowledge of eclipse/
ant/java; however, it doesn't meet your criteria of I prefer to keep
my app in one single project.

This is what I came-up with before libraries were available; it's not
fully automated. But, if you're old-school like me and host in a unix
(Mac OSX, Linux, Cygwin+Windows) like environment, you can setup
multiple projects in eclipse for each target, making one project your
working/master environment, and the others are just  build projects
(except for things specific to the target). Files that have no
differences and don't have any target differences are symbolicly
linked in each target project directory tree.  Files that are only
different because of target dependencies (most often due to java
IMPORTs like R.* for your resources/assets), are the part that require
a manual step before you perform a build. I create stream-editor (unix
sed commmand) scripts via shell language that I run before a build, it
reads the input file from the working/master project and re-writes it
in the target directory, I create marker comments in the source file
that are keys telling sed what to substitute/delete/etc. I'm sure
there is probably a way in eclipse to actually tell eclipse to invoke
the script as part of a build, but I've never bothered to go look.
This is way more complicated than libraries, but if your  background
is command-line oriented, it's pretty common-sense and easy. I tried
libraries the day they were first available and had too many small
issues and re-turned to this method. I suspect most of those issues
have been cleared-up, but my methods gives me some flexibility with my
source (that I find lacking (!!) in java) because it allows me to
modify the source as though the language had a decent pre-processor
built into it's definition. Some of the things my scripts modify can
probably (??) be worked around with java reflection and such, but my
working knowledge of java is not as good as it should be. And I prefer
compile/build/static solutions over run-time when ever available.

I'm purposely not providing examples because this method should not be
used unless you can comfortably implement it from the description
provided !!

I keep the shell script(s) in the target project tree, but they could
just as well be in the master/working project.

 What I just did in a similar situation, is use additional source folders,
 thus avoiding excessive use of libraries.

 I have two versions of the same app: one for Market and one for another
 store.

 My source directory structure has:

         SomeClass.java

 src-market
     package org.kman.FooBar.licensing
         SomeClassFactory.java
         SomeClass_Market.java

 src-another-store
     package org.kman.FooBar.licensing
         SomeClassFactory.java
         SomeClass_AnotherStore.java

 There are two versions of the same class, SomeClassFactory, in either
 additional sKostyaource folder, under the same name, in the same package, and 
 so
 I can just do SomeClassFactory.create() in the main body of application
 code, without worrying about which one it is. The implementation of those
 factories is different, each instantiating its own subclass of SomeClass -
  the one for Market or for AnotherStore.

 Now, the bulid setup:

 1) In Eclipse: src-market and src-another-store are added as additional
 source foldeKostyars in the application project. Then src-another-store has an
 exclude filter matching everything: **/*.*.

 This way, both folders are accesible for browsing / editing / source
 control, but only the sources inside src-market are compiled.

 2) For command line builds: I have a modified build.xml, and use
 sourcepathref with javac when compiling, to supply one or the other
 additional source folder, depending on which version I'm building.

 This additional path reference is set by a task that executes early in the
 ant build setup sequence, and makes the decision based on a property passed
 into the build script with -Dbuildtype=market or
 -Dbuildtype=anotherstore on the ant command line.

 Finally, there are two very simple shell scripts that call ant with the
 appropriate -D... flags.The shell script(s)


 End result:

 - The sources for both versions are accessible in Eclipse
 - The app can be built in Eclipse, defaulting to one of the two possiblebut

[android-developers] Re: Mac phone

[Jeff S]

I have an HTC EVO and a Macbook running Mac OS X 10.6.8.  I have been trying 
for a while now to get adb or Eclipse or anything else to recognize my phone 
on this computer.  
I can completely rule out any hardware issues because I can run the same 
computer with the same phone and the same cable and the same USB port and I 
boot to UBUNTU Linux instead of Mac OS and the phone shows up exactly as 
expected.
Also, I can tell the phone to mount as an external drive and it works under 
Mac OS or anything else.
I once downloaded and tried an IDE from Google that had the exact same 
problem.  Several people complained about it and everybody was supposedly 
working on a solution.  I haven't heard of any solution.  Has anyone else?

[android-developers] How does WebView handle content:// urls internally?

Internally, how does WebView handle content:// urls?  Does it use something

[android-developers] Re: Activity Lifecycle Documentation Question

[Jeff A Knaggs]

Yes! Having mostly lurked over this list for the last year and half, I
see this thread come-up too frequently, and this area caused me a lot
of confusion. I don't want to change the thread, but want to emphasize
that to make intelligent suggestions, one has to understand the
process.  These questions actually seem to arise more from people with
a lot of experience to other programming environments and lacking in
Java depth rather than plain beginners and I think it is because
developers are fearful of making assumptions to fill in
documentation holes/conflicts because they KNOW that is where things
can  will break.  The whole scenario was even muddier for me because
I had constant questions in my mind as to the relationship of things
like Java static initializers to these life-cycle Objects (I knew
neither the framework (or similar frameworks and was new to Java
(still feel like a newbie)) - for instance when the process is killed
but the system decides to keep the Activitiy around, does the
framework re-do static initialization of the Objects if it re-uses the
killed activity?  Since the document doesn't say, the developer has to
black-box, then if the framework is every changed, unless you
programmed defensively (assume statics are not repeated) your
application may break. Clearer documentation would help a little (for
those that read it :-), saving Dianne,  Mark, and all the rest of you
very generous contributors (thank you!) time for other replies. I can
rock with documentation issues in most areas (I can always go peek at
the source), but activity life-cycle is the back-bone of every
application design; it deserves to be held to a higher standard, and
end-consumer developers need a high degree of confidence that the
process is accurately documented without having to look at the source
-- to me,  the documentation should be a contract between the
framework developers and the framework users (programmatically)...

thanks for all the replies and the people that are persistent in their
pursuit of definitive answers.

The problem persists.  By having the startAnimation in the view's

into a Runnable or TimerTask called by either a Handler or Timer
respectively.

Basically what I'm doing is this:

private Runnable fadeInInfo = new Runnable() {
public void run() {

findViewById(R.id.TextViewInformation).startAnimation(animationFadeIn);
}
};

View.OnClickListener clickListener = new View.OnClickListener() {

[android-developers] Re: Problems with View.startAnimation()

[Jeff Meyerhoff]

@Mark Murphy
That's a good idea but my goal is to have the view only appear after
screen inactivity.  So I want/need the ability to cancel the scheduled
animation.

@Romain Guy
It has been my understanding and experience that a Handler object
could be used to schedule things on the UI thread.  Yet if I use a
Handler, the behavior is the same as using the Timer (although that
could be due to different causes).  As I wrote before, I have tried a
Handler and runOnUiThread() to little success.

Although the problem hasn't been solved, thank you all for replying
and replying so quickly.

[android-developers] Re: NFC default app - thoughts?

[Jeff Hamilton]

With Android 2.3.3 the tag dispatching has been improved quite a bit.
See the docs at http://developer.android.com/reference/android/nfc/Tag.html
for details on how it works now.

We generally would like to see people deploying tags using NDEF data
on them since it's much easier to deal with for developers. For
example, we inspect the first NDEF record in the first NDEF message
and build an Intent based on the content. If it's a URL we fill in the
data field on the NDEF_DISCOVERED intent, and if it's MIME data we
fill in the type field on that Intent. This lets developers filter for
tags that contain only data they're interested in.

Also, NDEF can be stored on many types of tags so you don't have to
worry about custom tag protocols when writing apps.

[android-developers] Change Resolution Policy when screen orientation changes

[Jeff]

I have a Live Wallpaper using AndEngine which has several small images
floating around the screen. I can set the initial screen orientation
and RatioResolutionPolicy without any problems, but if I rotate the
screen (or slide the the keyboard on some devices) and trigger a
ScreenOrientation change, the ratio is off because it's trying to
stretch each image since the ratio has changed. I.E. the width is
originally 480 and height is originally 720, so 720/480 = 1.5, but
when the screenorientation changes/rotates, the images try to fit into
480/720 ratio (0.67).

I have confirmed onResume is called when the screen is rotated, but
there doesn't appear to be a way to re-set the Engine using the new
height/width.

I've always used Chrome.  At least for this 'update app or save'

I did get a second follow-up, canned reply from Google:

'Hello,

investigating your report. We hope to have a resolution soon, and will
contact you when we have an update or if we need further information.

4. Set Normal screens to true, set Large screens to true, set Any

This is the XML:

[android-developers] Re: How to handle major revisions to OpenGL game in Android Market

[Jeff Boody]

What version of Android guarantees a hardware accelerated OpenGL ES 2.0 
context?

If your app specifies that it uses OpenGL ES 2.0 in the Android
manifest then it will only show up on the Market for devices which
support it.

For example:

uses-feature android:glEsVersion=0x0002/

I would like to limit limit these devices to the 1.x branch version of the app.

The early Android devices don't support OpenGL ES 2.0 so your new app
wouldn't show up in the Market for old devices.

How can I have 2 apps in the Android Market that have the same
name?  I'd rather not have to append some word like 'Pro', 'Extreme',
etc. on a new application since my current users that have sufficient
hardware to run the 2.x branch would not be automatically updated.

I think it would be difficult for users to differentiate between the
two apps with the same name so I would recommend having a different
name.

Is the solution to add code to the 1.x branch that checks the hardware on
startup and posts some message that they should download the new 2.x
branch app instead?

I think this is a good idea.

You can figure out if a device supports OpenGL ES 2.0 when it is
started by looking at the EGL configs to see if any support the
EGL_OPENGL_ES2_BIT.

[android-developers] Re: OpenGL glScissor not working on HTC phones

[Jeff Boody]

I do not do a gl.glClear(GL10.GL_COLOR_BUFFER_BIT); so the bits that were 
drawn previously should remain.

Actually this isn't the default behavior.

I think you need to request EGL_BUFFER_PRESERVED for the
EGL_SWAP_BEHAVIOR.

Unfortunately this currently (froyo) isn't possible because Android
only supports EGL 1.0 + some extensions.

The eglSurfaceAttrib() API entry point was added at a later version of
EGL.

[android-developers] Google Market cancelling orders

[Jeff A Knaggs]

All of a sudden, since the Market underwent it's recent multiple
country expansion, I'm seeing, on  a fairly regular basis,
cancellations with a subject:

Order XYZZY has been cancelled by Google

With an explanation that boils down to:

...because we were unable to verify that buyer's account
information...

So far it's all been with customers' billing addresses in S. Korea?

Wondering if any other developers with paid apps are seeing an
increase in these types of cancellations and if they are clustered to
any particular country?

[android-developers] How to create custom controls that mimic real device's UI?

[Jeff Gross]

I want to create a button that looks exactly like a CheckBox (same
size, same button face color, etc.), but instead of a checkmark, has a
square with a configurable color on it. My solution was to subclass a
View, set the background resource to a shape drawable which mimics the
CheckBox background and then override onDraw() to put the colored
rectangle on top. All this worked great in the emulator, but when I
tested it on a device, I quickly learned that devices have their own
stylized controls and my control looked out of place.

I looked at the built-in Android resources and found that
android.R.drawable.button_default_small might work nicely as the
background resource. However, the button face is not centered within
the 9-patch image, probably because of the drop-shadow so it makes it
hard to position my colored rectangle. Also, I'm not sure how to find
the dimensions of a CheckBox to size my control --
android.R.dimen.default_checkbox_size seems like a good place, but it
doesn't exist :-).

What do others do to make custom controls that integrate well with any
device's UI?

Thanks,
Jeff

[android-developers] Re: Record audio problem on the LG Ally

[Jeff Knaggs]

I'm curious, you do a copy with C++; did you do this because you
assumed/thought you needed the extra speed boost?  I.e., not because
you're then going to use a bunch of other (already written ;-) C++ to
process the data).  If the answer is YES -- for speed, did you do
any benchmarking to see if this was truly an issue? And, if YES, would
you be willing to share the benchmarking data?

On another note, would you mind if I emailed you directly on some
question related to audio but unrelated to this thread?  If you decide
that topic is worthy of being posted/shared in this group, we can move
it over.

[android-developers] Re: Rapid Android Development with AML, looking for feedback

[Jeff Rowberg]

 1.) How is AML different from using  HTML with  Webview?

I have an ongoing and interesting discussion with John Coryat about
that very thing, after he suggested using WebView to avoid reinventing
the wheel. There are situations where you could effectively use either
WebView or AML to accomplish your goal, and it will depend on your
preference and/or familiarity with Java vs. HTML/CSS/Javascript.

My understanding of WebView before talking to John was almost zero,
but I have since learned more. It surprised me to find out that the
Gmail app uses WebViews, and I'd love to find out how exactly (I'm
guessing for message rendering, but maybe other areas as well). Here
are the differences I came up with originally--please keep in mind
that I now know these are not all totally valid points:

1a. WebView displays HTML/CSS/Javascript, but does not provide web-
based access for directly creating or responding to native UI
components.
1b. AML dynamically interprets the markup to create native UI
components and capture events.

2a. WebView presents a browser-like interface, so that tapping on a
link (for example) is really directing the WebView to a new URL, and
not firing a click event within the same Activity.
2b. AML (as mentioned in 1b) attaches and handles native events.

3a. Apart from some outside control by the app, WebView actions all
take place within the same Activity (where the WebView object is
placed).
3b. AML blocks may define multiple unique Activities which can have
objects and events that may direct the user to completely new (and
potentially dynamic) Activities or Intents.

John has explained that WebView does indeed provide a way (the
addJavascriptInterface() method) to use Javascript inside the WebView
content to interact with Java in the native App code, even firing
events and moving to new Activities. Therefore, all three points above
can be overcome at least in a limited way by using WebView. But it
doesn't seem efficient to use this kind of method to attempt to create
a 100% dynamically built native app, which is what I'm going for.

Some people will always prefer a native implementation for some
projects, either because of the visual differences, or because it's
almost definitely going to be faster, or both. While AML probably
wouldn't be faster than WebView if every single user action resulted
in a request/response/parse/interpret/build operation, I think the
actual flow will be very different.

My goal is to have a web application send the complete collection of
the whole app interface all in one shot, except for 100% dynamic
aspects like search results or detailed views of every discrete data
entity. This way, aside from the initial load, the app will be much
faster and cleaner than a simple web-based version could ever be.
Since a decently complex Activity could be created in perhaps only 2K
of AML data, it is reasonable to assume that a dozen or more
individual Activities could be built and sent to the device all at the
same time. With a clever bit of short-term caching and background
loading, it might even be possible to completely hide the fact that
each layout was built on-the-fly by a remote host.

I don't want to build a one-page-at-a-time query/response library,
since that would have minimal to no benefit above other options. I
anticipate that AML will be used mainly with web app APIs that take
advantage of multiple views and caching, and not by just directing the
app to parse whatever data is at http://aml.mywebapp.com/index.php;
and then browsing page-by-page using a limited but native interface.

Hopefully that all made sense, and is logically sound. :-)

 2.) I would use it right away if it were available for RIM's OS. That
 platform can immensely benefit from a well supported and efficiently
 implemented markup language for UI.

I haven't thought about supporting that OS, though I definitely don't
see why it couldn't be done. I'll keep it in mind and try to do some
research in that direction.

Thanks for your input!

Jeff

[android-developers] Re: Rapid Android Development with AML, looking for feedback

[Jeff Rowberg]

Hello again everyone,

Due to the response I got from DZone, I've migrated my AML project to
its own website, which you can find here:

http://www.amlcode.com

My quest for feedback and input from the Android development community
is still going on though, so if anyone has any suggestions, ideas,
criticism, anything at all, I'm wide open to what you have to say.
Specifically, here's what I'm trying to find out:

1. Would you use this for your own app?
2. What would it need to do in order to be most useful?

[android-developers] Rapid Android Development with AML, looking for feedback

[Jeff Rowberg]

Hey everyone,

I'm pretty new to Android development, but I'm experienced with Java, C
++, and PHP, so I've been able to pick up a working knowledge pretty
quickly.

I'm looking for feedback on something I've begun to create,
specifically for my needs but definitely with potential for the
general Android development community. It's a simple markup language
that can designate layout and behavior for apps in a way that is very
easy to write but directly uses the native UI. It's a set of template
layout files (in /res/layout) and classes (in /src) that you include
in your project to enable this functionality. The implementation code
you have to write to use it is very, very simple.

My goal is to be able to have an app that is structurally built using
native code, but where the content, layout, and behavior are
controlled by an external source (a web service in my case). That way,
the app behavior will change automatically as the web service is
updated to include new features. I have seen tools like Rhomobile and
Appcelerator, and while they are great for certain needs, they don't
do exactly what I'm looking for.

I've called the code library that I'm working on AML, for App Markup
Language. It's simple, structured XML that the code parses and
dynamically builds layouts and views from. It's definitely still in
its infancy; there are no specifications or documentation yet, and it
is still missing a lot of important features (specifically, dealing
with events and processing inputted data). But hey, for being only
four days old, I'm really pleased with how it's come out so far.

For a few more details and some example code and screenshots, go here:
http://www.sectorfej.net/2010/07/10/rapid-android-development-with-aml

A sample snippet of AML looks like this: (hopefully the formatting
won't break in the post)

aml
  input type=buttonTest Button/input
  input type=checkboxTest CheckBox/input
  input type=togglebutton checked=yes /
  input type=imagebutton image=drawable/icon /
  input type=textTest Text/input
  input type=passwordTest Password/input
  radiogroup
input type=radiobutton checked=yesRadio Button 1/input
input type=radiobuttonRadio Button 2/input
input type=radiobuttonRadio Button 3/input
  /radiogroup
/aml

It's WAY simpler than the /res/layout XML you'd have to build (the
linked page shows what it would look like there for comparison). It
feels a lot like HTML, but it isn't quite the same. It is very simple
and straightforward though, and supports features like font size and
color, background colors, tables (with colspan), alignment and
padding. I'm working on more critical features now, like specifying
multiple activities and being able to switch between them.

I'm sure that AML can't solve every problem, and a lot of native code
will still be required for certain kinds of applications. It isn't
going to be able to simply everything you can do with Android (games
come to mind). But for data-centric apps, or especially apps that are
primarily just mobile interfaces to web services, it could be a huge
help, especially as more features are added.

I have two questions for all of you here:

1. Would you use this for your own app?

2. What would it need to do in order to be most useful?

I usually only think of the features I need, but I know I'll be
missing out on a lot if that's all I do. So please, feel free to give
any feedback, comments, suggestions, or otherwise. If you know of
another project that is doing something similar to this, I'd be really
interested in it. I googled for a bit but didn't see anything like it.

Overall, I do have to say that coding for Android is a lot of fun.
Seriously. I was a little worried a first, but not anymore.

Re: [android-developers] AIDL, Binder, ResultReceiver, and Performance

[Jeff Sharkey]

 If the purpose of this code (and I haven't looked at it to know) is to send
 a command to the service and get told later when it is done, then this is a
 reasonable approach.

Yep, that's exactly what I'm using it for.  I'm kicking off a heavy
background sync, and use an optional ResultReceiver to pass back
success/failure along with any Exception text for Toast'ing to the
user.


 Not my team's app...  I've not looked at the code, either. :}

The app was written by two engineers on the Android team, but not
anyone specifically working on the framework.

[android-developers] Android emulator problems

[Jeff Colapietro]

So, I've been doing the android tutorials and every time I try to load
the emulator it gets to the waiting for HOME step and then cancels.
It will load the emulator, but it will only get to the screen with
ANDROID across.

I rebooted my computer redid the tutorials and cleaned the projects
and tried again.  This time it worked after a while, but when the
emulator actually loaded, my app wasnt on the device.

Can someone please help me out, I'm not sure if i messed up
configuring eclipse or what I'm doing wrong.  Thank you

[android-developers] stop/prepare MediaPlayer issues

[Jeff B.]

Hello,

I have an ImageButton that plays a sound whenever it is held down and
stops as soon as you let up.  To do this I register an onTouch handler
and operate on ACTION_DOWN and ACTION_UP MotionEvents.  The code is
below.  The idea is that when the ACTION_UP comes in I first call
stop() and then I re-prepare the sound so that it is all ready for the
next start() in a subsequent ACTION_DOWN.  I do this instead of start/
pause because I need the sound to start from the beginning each time
and the seekTo() call is asynch which seemed to complicated the
logic.  The problem I'm having is that every now and then if I'm
really beating on the button (i.e. clicking it rapidly and for
different durations) I will hit the illegal state exception.  The
debugger log shows that I am in MEDIA_PLAYER_PLAYBACK_COMPLETE (128)
when trying to call prepare().  As you can see below, I only try to
call prepare after I have called stop.  So this would imply that stop
is somehow either asynchronous or the two operations are being allowed
to happen in an overlapped fashion.

So two questions:  1) does anyone have an explanation for what I'm
seeing?   2) is there a better/cleaner way to do what I'm trying to do
in general?  This is my first android app so it's very possible I'm
missing the boat on something.

public void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);
setContentView(R.layout.main);

Context appCtx = getApplicationContext();

// button init code removed

mSoundBeep = MediaPlayer.create(appCtx, R.raw.beep);

mImgBtnBeep.setOnTouchListener(new OnTouchListener() {
   public boolean onTouch(View v, MotionEvent event) {

   switch (event.getAction()) {
  case MotionEvent.ACTION_DOWN:
 mSoundBeep.start();
 break;

  case MotionEvent.ACTION_UP:
 if (mSoundBeep.isPlaying()) {
mSoundBeep.stop();
 try {
   mSoundBeep.prepare();
} catch (IllegalStateException e) {
   mSoundBeep.release();
   Context appCtx = getApplicationContext();
   mSoundBeep = MediaPlayer.create(appCtx, R.raw.beep);
} catch (IOException e) {
   // TODO Auto-generated catch block
   e.printStackTrace();
}
 }
 break;
   }

   return false;
   }
});

[android-developers] Change Default Package Name of R.java

[Jeff]

Hi all,
I am writing an app that has a consistent code base, but has different
resources that make it a new app. My ant script copies
AndroidManifest.xml, res and assets dirs for a particular app prior to
kicking off the build. This approach works great if all the apps have
the same application package name. However, I want to be able to
install more than one app from this common code base, so I must change
the application package name.

If I change the package names in each AndroidManifest.xml, then R.java
gets generated with the new package name. This causes all my
references to the resources constants in my common code base to throw
an error.

It would be great if I could specify the package name I want aapt to
use when generating R.java. Does anyone know if this is possible? Any
other suggestions?

Thanks,
Jeff

Re: [android-developers] Change Default Package Name of R.java

[Jeff Thorn]

I looked into Library Projects, but I am not sure if that helps me. I assume
I would put the Activity in the library, since it is what is used by each
app. However, that Activity relies on String values from
res/values/strings. Each app will have different strings. Therefore the
activity calls R.string.something to get the string from the resource.

In order to make each app its own unique app, I need to change the package
attribute of manifest element in the AndroidManifest.xml. This has the
unfortunate side effect of generating the R class with the app's custom
package name. Therefore, when the Activity common code base tries to look up
a string using the R class, it cannot find the class since it has a
different package name.

At this point I am thinking about creating an Ant target to replace the
package name in R.java. However, I feel like there has to be a better way.

Am I overlooking something? Can this be accomplished with libraries?

[android-developers] How to test onCreate with saved Bundle?

[Jeff]

My app launches the camera to allow the user to capture a picture.
Sometimes this causes the OS will kill my App to free up memory for
the camera. Once the picture is taken, my app starts back up where it
left off using the Bundle I saved in onSaveInstanceState().

My app had a bug where in the code that restores the state. Is there
anyway that I can simulate or test this case to make sure I am
restoring correctly now? It seems I am having trouble making this
happen when I want to test it.

Thanks,
Jeff

[android-developers] Handling Orientation Changes that occur in another Activity

[Jeff]

I am having an interesting problem and would appreciate any advice. My
app uses WebView as its primary view. Using a javascript hook, it can
launch the camera so the user can take a picture. The camera is
launched using

Intent i = new
Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);

When the camera starts, it makes sense to use landscape mode, so the
user naturally turns the phone on its side. After the user takes a
picture, control returns to my launching Activity (actually, my
Acitivity gets restarted because it usually gets destroyed to free up
memory for the camera on my Moto Droid). When my WebView gets
recreated, I restore its state from the Bundle I saved in
onSaveInstanceState().

Now everything looks ok, except the phone is still in landscape mode.
However, when the user turns the phone upright bringing back into
portrait mode, my WebView takes up only half of the screen. Somewhere
along the way, the scale of my WebView got lost. This seems like such
a minor issue, but it is driving me crazy.

Does anyone have an idea why this might be happening? What is the
correct way to preserve the scale of my WebView? I am hesitant to hard
code any scale factors because what looks good on my device may not be
the same for another.

Thanks,
Jeff

Hi Rajiv,
What changes should I make? I am saving the state in onSaveInstanceState and

Re: [android-developers] Handling Orientation Changes that occur in another Activity

Yes, I understand that. But my problem is that I don't want to make any
changes! :)  Yet somehow, the scale is changing somewhere along the line
between and I don't know the correct way to set it back. I don't want to
hard code any scale settings.

Re: [android-developers] Re: Handling Orientation Changes that occur in another Activity

[Jeff Thorn]

I have not defined these settings. I just want the WebView to fill the
entire screen. Until the camera is launched, the default layout and scaling
settings work just fine.

It looks like somewhere the Scale setting gets changed from 1.5 to 1.0 after
I call WebView.restoreState(). I don't want to hard code anything so I am
not sure of the best way to change it back.

[android-developers] We need developer feedback, STOP rating when customer has canceled order

[Jeff]

Please let us provide feedback on the market,  it hurt all of us
including Android!  The iPhone interface is so dumbed down that most
do not have problems.  I just got a bad rating because the user didn't
understand how Android works.
I attempted to explain the the user and he posted that the interface
was complicated.

[android-developers] Re: Participate in app promotion experiment

[Jeff Knaggs]

Here's another number my app, punch, is not free. At the beginning
of John's advertising experiment, the price was $1.69. I showed no
change in order rates after the first ~5000 impressions, and
subsequently lowered the price after ~1 to $0.99.  At that point
there was a consistent daily average uptick. That increase accounted
for 1.43% of the 420 click-throughs. Another number I'll share (that
really can only be applied to my app) is the cancel ratio: ~43%
cancelled (uninstalled/refunded).

Background on my app so you don't read too much into the numbers. I
wrote punch to get my feet wet on the whole process: from learning
Java (new to me), wanted to experiment with accelerometer for
potential use in a much more complicated project, to marketing
strategies. It's a very simple app --uses accelerometer: waits for non-
movement (kind of), tracks movement, detects non-movement (kind of),
reports acceleration and time of movement (kind of).


That said, I consider these facts as other confounding variables:
(1) only on market for approx 7 days before the experiment started.
(2) for most phone owners I predict this is, at most, a try-once game,
get-bored, rarely use again (if at all)
(3) there is a free game by somebody else with same basic
functionality, not as polished (not that mine is exactly polished
either). As an aside the free game has a fairly large download count
and a youtube video with a bunch of teens (?) playing it (over 11,000
views). There is an iphone game as well, with youtube video (over 7000
views).
(4) my app does put an admob banner up (some people may not like this
and uninstall?)
(5) I purposely do not put this in any of the game categories as part
of my personal marketing testing is to play around with naming and
categorization. punch is under applications:health with my Market
text implying one can use it regularly as part of a metric for
exercise.

[android-developers] Re: android tablet emulator creation

[Jeff]

In Eclipse, select Window menu, launch Android SDK and AVD manager.
Create a new AVD with target Android 2.2 and set the resolution you
need.

[android-developers] Handling Unsupported Content Types in WebView

[Jeff]

My app uses WebView to display most of its content, which it receives
from various remote sources. One of the pages I load has a link to a
URL that returns a PDF. The url gives no indication that it is a PDF.
Only the response content type shows it. Since webview does not appear
capable of displaying PDF's, the app does nothing when a user clicks
on this link.

I would expect there to be some method in WebViewClient that I can
override to catch this, but I can't seem to find one. onReceivedError
is not called. I don't believe anything else is.

Is there a way I can detect this and other unsupported content types
so I can at least display an error or do something? Right now the app
just does nothing, which is not acceptable.

Thanks!

Jeff

[android-developers] Re: Avoid restarting background threads on orientation change

[Jeff]

Ok, I believe I have made a little progress on this. It looks like I
can use onRetainNonConfigurationInstance() to save an instance of my
thread objects and then call getLastNonConfigurationInstance() to get
them back when the Activity is restarted.

This leads me to a new questionwhen do I actually destroy the
threads then? Part of me is wondering if I even need to bother
destroying the threads - won't the OS do that automatically when it
needs to? One of the threads has an open database connection. I
imagine that should be handled more gracefully. The question is when
should I do this?

When an Activity starts, there is a way for you to tell if you have
saved state. When the Activity ends, I wish there was some reliable
way to determine whether the Activity is going to restart right away
or if its being destroyed for good.

Perhaps I am overlooking a fundamental aspect of the Activity
lifecycle in relation to background threads.

Any advice would be greatly appreciated.

Re: [android-developers] Re: Avoid restarting background threads on orientation change

[Jeff Thorn]

As always, thanks Mark!

I definitely see your point - its better to do short chunks of work in an
AsyncTask than creating long running background threads.

My app makes a lot of http requests. After the download is complete, it
updates a database. I thought it would be better to create a single
background thread that does this work and then notifies the UI when its
finished. I thought this would be more efficient than opening a network
connection, opening the database, doing work, closing the database, etc.
each and every time. I suppose I could open the database in the main
Activity thread and close that in onDestroy and pass it to the AsyncTask
each time.

 As soon as their work is done. All else being equal, choose a model where
 you do not keep your own threads hanging out forever (e.g., use AsyncTask
 rather than forking your own threads).

  Part of me is wondering if I even need to bother
  destroying the threads - won't the OS do that automatically when it
  needs to?

 No, it will not, except by terminating the process, which may not happen
 for quite some time after your activity is destroyed. This yet another
 reason to use AsyncTask rather than forking your own threads -- threads
 *Android* forks *Android* is responsible to clean up.

 Moreover, please bear in mind that your activity may be in a stopped state
 for an extended period of time (a.k.a., days). Your goal, while stopped,
 should be to avoid doing anything much. This is yet another reason to
 design your application to avoid forking your own threads that hang around
 indefinitely, but rather do your background work in short discrete chunks
 in AsyncTasks.

  One of the threads has an open database connection. I
  imagine that should be handled more gracefully. The question is when
  should I do this?

 As soon as your work is done.

  When an Activity starts, there is a way for you to tell if you have
  saved state.

 In your case, if getLastNonConfigurationInstance() is not null, you have
 saved state, in the form of the object returned from
 getLastNonConfigurationInstance().

  When the Activity ends, I wish there was some reliable
  way to determine whether the Activity is going to restart right away
  or if its being destroyed for good.

 Call isFinishing().

Re: [android-developers] Re: Avoid restarting background threads on orientation change

I took your advice and refactored my code to replace any long living
background threads with AsyncTasks. Wow!!! I cannot begin to tell you how
much it simplified my code. Thank you so much for the very valuable advice.

 IMHO, that's a premature optimization. Moreover, it does not preclude the
 use of AsyncTask:

  I suppose I could open the database in the main

  each time.

 Likewise, if you use an HttpClient with a ThreadSafeConnectionManager, you
 can do the same thing for your HTTP connections:

[android-developers] Re: Clarification on loading local images with WebView

[Jeff]

Thanks Mark. I could use some advice on the best approach to this
problem

The image that I am trying to display is very large and I want to
preserve its detail. So I am including it in the apk in the assets/
directory. My app almost exclusively uses WebView to display content.
I am trying to figure out the best way to show this large image from
one of the html pages loaded by my WebView.

1. Should I load it with my WebView? I thought I could use img tags
with urls like file:///android_asset/myimage.png. But this does not
seem to work.

2. Can I start a new Activity with an Intent that shows the image in
the default image viewer? This might be nice if it allows zooming and
scrolling. In this case, what is the URI I should use to an image in
my assets directory?

3. I can write my own Activity to load the image from my assets
directory. Does ImageView support zooming and scrolling?

Any advice on which of these approaches makes the most sense? Or is
there another approach that I am overlooking all together?

thanks,
Jeff

  A) should what I am doing above work (because its not)

 Since you are loading the Web page from the Internet, I imagine WebView
 will block local file access. This is not significantly different than
 regular Web browsers, last I checked. Otherwise, Javascript could
 rummage around the local file system, grab data, and send it hither and
 proverbially yon.

  B) If it only works on some versions of the platform - which versions?
  How should this be addressed when I can't guarantee what version of
  the platform users are running?

 Try creating a ContentProvider to serve the image, and see if you have
 better luck with a content:// URL.

Not directly, but you can use the 2D graphics API (e.g., Canvas and

[android-developers] Re: HTC Incredible - images not showing up in Gallery

[Jeff]

I have heard of some issues with the sdcard storage on the
incredible.  It's has the 8gb internal and the optional external.
This has caused some other applications problems because they look for
the sdcard (specifically the ny subway map app which stores the files
there).  I am not sure if the sdcard and internal storage are getting
confused inside the apps.

On May 9, 2:48 am, Martiño martino.figue...@gmail.com wrote:
 Hello,

 I'm making an alternative camera App. As you might expect my App
 involves taking pictures and saving them to the sdcard.

 On most phones (and the Emulator) everything works fine, pictures
 appear in the built-in Gallery App straight away.

 However on the HTC incredible images only appear when the user
 restarts the device. (I'm talking about an HTC Incredible phone with
 an sdcard, I know some of them shipped with internal storage only, but
 this is not the issue I'm talking about)

 The code I'm currently trying goes like this:

        public static boolean savePicture(Bitmap bitmap, int quality,
 String label, Context context) {

                 ContentResolver resolver = context.getContentResolver();

                 // Save the name and description of an image in a 
 ContentValues map.
                 ContentValues values = new ContentValues(3);

                 values.put(MediaStore.MediaColumns.MIME_TYPE, image/jpeg);
                 values.put(MediaStore.MediaColumns.TITLE, label + .jpg);

                 // Add a new record without the bitmap
                 Uri uri = resolver.insert(Media.EXTERNAL_CONTENT_URI, values);

                 // Get a handle to the file for that record, and save the 
 data into
 it.
                 try {
                         OutputStream outStream = 
 resolver.openOutputStream(uri);
                         bitmap.compress(Bitmap.CompressFormat.JPEG, quality, 
 outStream);
                         outStream.close();
                         context.sendBroadcast(new
 Intent(Intent.ACTION_MEDIA_SCANNER_SCAN_FILE, uri));
                 } catch (Exception e) {
                         return false;
                 }
                 return true;
         }

 I've also tried MediaScannerConnection.scanFIle() with no luck.

 I wonder is the problem is due to the HTC incredible being originally
 designed to operate with internal storage only, maybe the Gallery App
 has issues with media stored on the sdcard.

 Turns out it was not the webview, it was my provider : When browsing

 server so that its a lot lighter to download on their network.
 When I tried over wifi everything came back to normal.

 In the end I implemented a regular binary file download from my

[android-developers] shouldOverrideUrlLoading not getting called for file:///android_asset links

[Jeff]

I am using WebView to display web content in my app. Since I want to
keep all content in my webview and not launch the browser, I override
shouldOverrideUrlLoading and call loadUrl().  One of the pages has an
image that is very large, so I want to put it in the assets
directory.

When the user clicks on a link that starts with http:// everything
works fine. When they click on a link that starts with file:///android_asset,
shouldOverrideUrlLoading never gets called so my app never calls
loadUrl - hence nothing happens.

Anyone know why this is?

has a rather large PNG image. The image is large and detailed on
purpose because the idea is to use it as a map and allow users to zoom
in to see the detail.

Unfortunately, when the image is displayed with WebView, the quality
is horrific. I am assuming that WebView is attempting to do some image
optimization to reduce the size of the graphic.

Is there anyway to prevent it from doing this? I don't want the image
to lose any of its quality.

Thanks,
Jeff

[android-developers] Re: Stopping or Killing a Thread

[Jeff]

I don't know if this will help with your symptoms, but I'm just making
sure that the thread gets interrupted and the thread stops before the
surfaceDestroyed method returns.

If you interrupt a thread, the thread needs to expect the interrupt.

assuming that you are extending Thread (untested code)

public BallDropThread extends Thread{
//override run
public void run(){
while(!this.interrupted()){
//stuff to do
}
}
}
//then your surface destroy can look like this

public void surfaceDestroyed(SurfaceHolder holder) {
thread.interrupt(); //says that the thread should stop
try{
thread.join(); //make this thread wait for the other 
thread to
finish before returning
}catch(InterruptedException ie){
//handle the case if the thread.join is interrupt
//don't know if this will ever happen, if it can... 
throw a runtime
exception?, or reinterrupt?
Thread.currentThread().interrupt(); //reinterrupt 
because thrown
exception cleared interrupt and hope it's handled elsewhere
}
}

hope it helps
-Jeff

 The problem I am continuing to have is that SurfaceCreated gets called
 instead of onCreate when the app restarts. I was using the join()
 method which I thought terminates the thread but SurfaceCreated still
 gets called first.

 Is there a way to call onCreate from SurfaceCreated?

 Another solution I tried to just set the thread to a paused state (ie.
 setRunnable(false) ), and when the app restarts simply
 setRunnable(true) to run the thread again, but all I get is a black
 screen when I do this... All the settings, variables and graphics are
 loaded but nothing happens.

[android-developers] force WebView to wait for images

[Jeff]

When loading a page with WebView, images seem to appear one at a time
as they are downloaded or loaded from the cache. This gives the user
more of a browser type of experience instead of an app type of
experience.

Is there a way to make WebView wait until all images are ready on a
page before displaying the entire page?

Thanks,
Jeff

Thanks Mark.

Strange - I didn't get your response yesterday. I also didn't see the post
ever appear on the discussion list. Thanks for answering it twice!

 As I wrote when you asked this yesterday:

 At least for your initial page, you can make it invisible to start, then
 use a WebViewClient and onPageFinished() to find out when the page is
 fully-loaded, then make it visible. I've used this in conjunction with a
 custom RotateAnimation progress indicator, for example.

[android-developers] WebView wait for images

[Jeff]

When using WebView to load a page that has a number of images, the
images seem to appear one a time as they are available. This happens
even if the images are cached. This tends to give the user more of a
browser type of experience rather than an app type of experience.

Does anyone know if there is a way to make WebView wait until all of
the images are rendered before displaying the entire page?

Thanks!

[android-developers] BUG in SQLite? Cannot use Long Integers in Cache Database

[Jeff]

Has anyone been able to get Long Integers to work with a SQLite DB on
Android?

In particular, I am noticing some odd behavior with Webkit's Cache
Database. The expires column is always 0. After doing some testing,
I realized that SQLite will accept a value in the expires column up
to (2^31 - 1). Anything higher than this, and the value is always 0.

The cache database uses Date.getTime() to populate this field. Since
this is a long, the value is always 0.

Is this a bug in the Cache Database or the SQLite implementation?

Re: [android-developers] BUG in SQLite? Cannot use Long Integers in Cache Database

[Jeff Thorn]

I spent 2 days trying to figure this out, and wouldn't you know it...2
minutes after posting to the group, I think I have figured out what I was
doing wrong.

In order to check my work, I was exporting the database to my local computer
and opening it with SQLite Administrator. The values were appearing as 0
because the affinity of this column in the database was set as INTEGER. So
it while is appeared that these values were getting stored as 0, in
actuality they were just getting displayed as 0 in SQLite Administrator.

The true value of these fields are indeed getting stored properly. I just
had to CAST(expires as NUMERIC) in order to view them.

Sorry for the false alarm.

 Here is a list of data types that are allowed in SQLite 3:
 http://www.sqlite.org/datatype3.html

 Note that there is no official long data type.  It would be classified as
 INTEGER or REAL.  For actual long data types that don't seem to be stored
 well in SQLite you might do better to store as TEXT and do a conversion
 outside of SQLite.

 I am by no means a database expert though, perhaps someone with more SQLite
 experience will chime in with a better explanation.

[android-developers] Contacts is missing a very important function

[Jeff]

On 1.5 at least, which I have not confirmed on subsequent releases, it
is not possible to search or see company name.  This doesn't seem to
be available via gmail on the web either.  I don't understand why
contacts should only be viewable and searchable by first and last
name, ONLY.  This is a must have function, especially for anyone using
these products for business.

Also, the contacts lookup feature doesn't really work as it should,
certainly not like other features.  You should be able to do a search
for a contact, pick a contact and if it is the wrong one use the back
button to get back to your search. In most applications the back
button gets you back to your previous page.  When looking up contacts
you get back to nothing.

[android-developers] WebView HTML5 Cache Manifest

Unless I am doing something wrong, it does not appear that WebView
supports the HTML5 cache manifest. Does anyone know if there are plans
to implement this in the SDK anytime soon?

[android-developers] adp1 doesn't connect via usb

[Jeff Caldwell]

I have an ADP1. When I connect it via a USB cable to either a Debian or an
Ubuntu machine, there is no allow notification icon nor does lsusb show
the ADP1 as a connected device. I tried a factory reset, which did not alter
the behavior.


Any ideas?

[android-developers] Re: CONTEXT_LOST GLSurfaceView

[Jeff Boody]

See 2.6 Power Management in the EGL specification:
http://www.khronos.org/registry/egl/specs/eglspec.1.4.20090908.pdf

The error EGL CONTEXT LOST will be returned if a power management
event has occurred.

I think the EGL_CONTEXT_LOST error is handled automatically by
GLSurfaceView.

If your application starts rendering again when comming out of stand-
by then I think it is ok.
