No.

 I have several applications on the market place, today someone has posted a
 comment saying the application contains spyware, which is complete rubbish
 and not true, how can you prevent this kind of thing?

You can mark it as spam. That doesn't remove it, but it (probably)
won't display
at the top with the new Market client.

[android-developers] LocationManager using Network provider returns stale locations

2011-07-28 Thread Davy

Hi,

I have the following scenario

t1 : sitting at home - wifi connected - location manager using network 
provider returns the correct location (home)
t2 : I get in my car, use the location manager now with gps provider - 
returns correct locations throughout the trip (100km)
t3 : arrive at work - wifi connected - location manager again using network 
provider returns the location from t1, and not the current location. 
timestamp on the location resource object coming from the location manager 
is an up-to-date timestamp.

distance / time between t1 and t3 is 100km / 1hour

Is there some kind of caching mechanism that I need to be aware of, and can 
it be invalidated ? 

How can I force the locationmanager (using network provider) to always 
return an up-to-date location ? Both in t1 and t3, the phone is connected to 
a WiFi base station that is known to Google (capable of being correctly 
resolved into an address). between t1 and t3 the Wifi radio is on, but 
obviously not connected to a basestation, and the locationmanager is using 
the gps provider.

Also, sometimes, even when connected to a WiFi basestation, the 
locationmanager doesn't return a location (using a 30 second timeout). In 
all cases, the WiFi base stations can be resolved to an address.

Any ideas ?

Re: [android-developers] Re: google map marker

Android cannot give you an error of lines not supported.

Did you try modifying the code to work with your project or did you just
blindly copy paste? Did you change the variables and the XML files to the
ones you have in your project?

There are thousands of tutorials for this on the Internet. Google it.

Thanks

[android-developers] Re: How to get web data into TextViews?

2011-07-28 Thread endyk

hello Droid,


you can use this method to get return string from server


private InputStream OpenHttpConnection(String urlString)

InputStream in = null;
int response = -1;

URL url = new URL(urlString);
URLConnection conn = url.openConnection();

if (!(conn instanceof HttpURLConnection))

try{
HttpURLConnection httpConn = (HttpURLConnection) conn;
httpConn.setAllowUserInteraction(false);
httpConn.setInstanceFollowRedirects(true);
httpConn.setRequestMethod(GET);
httpConn.connect();

response = httpConn.getResponseCode();
if (response == HttpURLConnection.HTTP_OK) {
in =
httpConn.getInputStream();
}
}
catch (Exception ex)
{
throw new IOException(Error connecting);
}
return in;
}

private String DownloadText(String URL)

inputBuffer = new char[BUFFER_SIZE];
}
in.close();
} catch (IOException e) {

try call this function in your main code, where str is return string

[android-developers] Date Picker using xml layout - problem in android app

2011-07-28 Thread Sivasankar K

i have some problems in using the date picker from xml layout.

in my app when the user clicks a text view a custom dialog box opens. In the
layout of the custom dialog box i am showing a date picker which i have
place in my xml file. When it appears in the app i want a particular date to
be viewed, for example as 01 Jan 1950. Every time it opens it is showing the
present date only.

In my dialog box i have a set and cancel buttons. The Cancel button cancels
the dialog box where as when i click the Set button i want the current date
to be stored to a String.

In another activity of my app in a custom dialog box i want to show a date
picker only with the year columns, i dont need the date and month columns.
How to get it, please help me friends

[android-developers]Proximity Alerts in LocationManager not working as expected.

2011-07-28 Thread deepak subramanian

Hi everyone,

I have an application which needs to call a new screen if it comes within
the proximity of a few locations. So I am using the addProximityAlerts()
function as follows: But this does not work at all. My code is shown below

*public void setupLocationMonitoring(Intent newIntent) {

for (int i = 0; i  locations.size(); i++) {
newIntent.putExtra(widgetId, i);
newIntent.setAction(IntentAction);
PendingIntent intent1= PendingIntent.getBroadcast(HaiMap.this,
i, newIntent, PendingIntent.FLAG_CANCEL_CURRENT);
double lati=(double) (locations.get(i).getLatitudeE6()) / 1E6;
double longi =(double) (locations.get(i).getLongitudeE6()) /
1e6;
lm.addProximityAlert(lati,longi,200,0, intent1);
}
}
*
The Manifest entry for the broadbase receiver which is supposed to receive
the intents is as follows;
*
  receiver android:name=com.deepak.sample.receiver.MyBroadCastReceiver
intent-filter
action
android:name=com.deepak.sample.view.HaiMap.intentWiki/action
/intent-filter
  /receiver*


I am trying to create proximity alerts for a few locations with the
following code. I have searched for some time but there is no good answer to
this question anywhere on the web.

Deepak

[android-developers] Game made with andengine has weird crashes.

Hi,

I have made two versions of my desktop game on android using andengine. One
uses a normal image background and the other has augmented reality as the
background.

The links to both the games are:

https://market.android.com/details?id=com.raghavsood.speedball
https://market.android.com/details?id=com.raghavsood.speedballar

One common problem in both the games is that sometimes the moving ball
disappears. This in itself does not cause a crash or anything like that but
spoils the game as the ball is kind of the point.

The next few problems are related only to the augmented reality one (link 2)

1) When the game is started sometimes it displays the ACRA toast saying my
app has crashed but then continues straight on and opens the game which
works fine.

2) Sometimes the game crashes on pressing the back button, opening it after
pressing the home button.

The two stacktraces below appear in both the problems.

The description of your problem kind of sounds like a catch-22.
Someone needs to tell a ListView something, yet they don't know what
that ListView is.  Does that sound problematic to you?

At some point, the thing in your system that has updates for a list
needs to notify the list itself.  Usually, one would do this through
the Adapter that backs the list.  You'll need some sort of bridge
between the two, perhaps a listener type interface or a broadcast.

[android-developers] Call Background Service from Intent

2011-07-28 Thread Sivaprakash

Hi

I have written an intent for Camera device, which will basically listen for
snaps. If any new photo taken it will trigger my intent. I want to call a
background service (which I have implemented already) from the intent to
upload the file. How can bridge these two? Any samples or explanations would
be appreciated.

Thanks

 You are making too many assumptions, but have fun with it.
 I actually write all of my C code in a giant main() function and
 I never ever check return codes. I am that good. I pass around
 NULL pointers like crazy, but it's OK, because I'm a lucky guy.
 Satisfied?

No, I'm not, because you're not using logic to address to issue at
hand.

  If you are that kind of engineer (and I would argue that you are not
  actually an engineer), then don't use Java.

 Java is old. And because it's 'enterprise', it won't change much.
 Checked exceptions is not the only problem with it. So yes,
 when possible, I use more modern alternatives.

Go on.  I'm listening.  Please don't just say do your own research
or smart people write about this.

  The whole point is, that with checked exceptions you are forced to
  handle or re-throw/declare them even if you don't what to do that
  *in that particular part* of your code. Nobody is saying 'we will
  ignore all exceptions and keep our fingers crossed'.

  Truthfully, how often do you really NEED to ignore checked
  exceptions?  It does come up, but not enough for me to get upset that
  I have to do it.  For me, it's a few extra lines of code in a few
  places.

 Again, I never said ignore. I said 'don't handle in that particular place'.
 A few extra lines of code multiplied by a hundred places makes for
 a lot code bloat. Don't you just love it when you have to handle
 IOException when calling close()?

Please answer my question above.  How often?  In my experience (16
years) it's not common enough to complain about.  There are cases,
yes, but only on shutdown/termination.  I don't obsess on those
cases.  I do them one and be done with it.  It takes at most 1 minute
out of my day.  If you can't spare that 1 minute, then don't use Java.

 We can go on forever, but there's not much point. Have fun with
 your exceptions.

Please make a case for your alternative.  I'm listening.  Please make
it relevant to Android development, considering the forum in which
we're participating.  If you have an axe to grind against Java as a
language, I suggest you do it elsewhere.

[android-developers] How can we keep a particular application on the top always

2011-07-28 Thread Ankit

Hi ,
I want to keep my application ( Application A ) on the top always in
Android.  Application A is not a full screen  application, it is a
floating window or dialog theme based application. The Application A
can launch other application.\ from its own UI portion also other
applications can be launched from background from Home screen
shortcut / Application Launcher screen.
How can we do it?

Also the application which are in the background with Application A on
top should work normally. e.g. it can Launch other activities (of it
own own or some other application), dialog etc.

Second doubt/ requirement  is -  Activity Y is below Activity X,
Activity X is below Activity A (of Application A) . Activity X has a
close/exit button which would finish its own activity X. Now when that
button is pressed the activity get closed but leaves a black screen
below activity A.

Why does this happen (i think may be because it requires the Back
stack to be rearranged)  and is their a turn around way of being able
to do this.

If any  application in the background  launches another activity/
application then also my application ( Application A ) should come at
the top of the launched activity/application.

Thanks ,
Ankit

 Can anyone help me ?

At the end of your build, is there something not working?  I think
what you're seeing is just a warning and not a significant error.

 I have implemented similar feature on desktop applications using

 I was planning to use the same on Android but am not sure if openvpn

   I am implementing a UDP application on Android.

   start downloading/retrieving webpage. The receive(...) function won't
   return any data until the browser stop its downloading. I did a
   measurement that the receive(...) function returns data after almost
   700 milliseconds. It seems that all the packets to our application are
   hold until the browser is done with its network activity.

   I am looking for the solution to still receive data over the network
   even there is other application sends or receive data over network at
   the same time. It would be better if the solution can make our
   application have higher priority in using the network.

Re: [android-developers] Re: Update activity UI from service using observer pattern

2011-07-28 Thread Vadym Khondar

I finally figured out the issue.

For those who might encounter the same not to lose their time.

The answer on my initial question is really YES, observer pattern
works in decribed scenario with local binding to service which runs
AsyncTasks.

My problem happened because ListView calls getView() for each row
twice when its layout_height=wrap_content.
That is why really I've updated not the view that was shown.

It took near 2 weeks to understand that problem is not in code! Phew!

Tutorials I've found (including with help of this email list) do not
explicitly state possible issue (and actually, I think, won't work
just like mine if one changes layout_height) however they are of great
help to understand how to work with ListView in android correctly to
make use of its optimizations.

Anyways, struggling with this simple problem I investigated
implementation of ProgressBar, TextView, wrote several test apps,
decompiled AndroidMarket app and read lots of stuff :)

Re: [android-developers] Re: google map marker

I am not telling you to blindly copy paste. On the contrary I am telling you
not to copy paste anything blindly. If you had bothered to read my mail
properly you would have noticed that I asked you if you had changed the code
given by Abhishek to be usable with your project. That is changed the
variable names, changed the R.class references to what you are using. I also
pointed out that if you Google this problem you will get many tutorials that
clearly explain what you are trying to achieve.

 You are making too many assumptions, but have fun with it.
 I actually write all of my C code in a giant main() function and
 I never ever check return codes. I am that good. I pass around
 NULL pointers like crazy, but it's OK, because I'm a lucky guy.
 Satisfied?

 No, I'm not, because you're not using logic to address to issue at
 hand.


Well, neither are you. You are assuming something I never said,
and are building your 'case' from there. As you see, this doesn't
work.


 Again, I never said ignore. I said 'don't handle in that particular place'.
 A few extra lines of code multiplied by a hundred places makes for
 a lot code bloat. Don't you just love it when you have to handle
 IOException when calling close()?

 Please answer my question above.  How often?  In my experience (16
 years) it's not common enough to complain about.

Pretty darn often. Every time you need to deal with file IO, connect to a
database, or call a network service. Consider a simple data access
interface. You might have a file implementation and a database
implementation with the same interface. You can't exactly declare it
to throw IOException *and* SQLException, but still want to make
people handle the exceptions your implementation throws. So you
invent a checked DataAccessException and declare it in your interface.
You feel pretty satisfied about your abstraction. Then you implement
it, wrapping your IOExceptions and SQLExceptions in the shiny new
DataAccessException. People use your classes and need to handle
errors at some point. But what does DataAccessException mean? Not
much. So, they dig in, get the cause and go from there. Neither
compiler checking, nor your design by contract have made people's
life easier.

Or say you need to implement a third party interface. Your
implementation needs to use a file, but the interface doesn't declare
an exception. You need to stick to the original interface's contract!
So what do you do: log and swallow the exception? wrap in up in a
RuntimeException? declare all interface methods to throw
Exception? None of those are too good. And just the time spent
considering it is wasted.

You say there is value in checked exception: they force lazy
programmer's to deal with errors; they make your contracts
explicit; the compiler can check them for you. OK, maybe.
But the problems they produce: breaking encapsulation, forcing
people to write boilerplate code when they don't need to, making
it hard to evolve your design, proliferating endless hierarchies/chains
of Exceptions far outweigh the benefits.

 There are cases,
 yes, but only on shutdown/termination.  I don't obsess on those
 cases.  I do them one and be done with it.  It takes at most 1 minute
 out of my day.  If you can't spare that 1 minute, then don't use Java.

See above.
It's about writing less boilerplate code and being more productive.
Multiply your one minute by the number of times you've had to deal
with checked exceptions when you didn't really need or intend to,
just because the language forces you to (in your long Java career),
add in  the time spent considering whether an Exception should be
checked or unchecked; even the time spent in this thread, and you
will see that you have wasted a lot of time.


 We can go on forever, but there's not much point. Have fun with
 your exceptions.

 Please make a case for your alternative.  I'm listening.  Please make
 it relevant to Android development, considering the forum in which
 we're participating.  If you have an axe to grind against Java as a
 language, I suggest you do it elsewhere.


I don't have an axe to grind. Java is a good language. Lots of good
ideas in it. As for Android, it's a good fit for mobile development:
it's widespread, it's fairly high level, but it still lets you get close to
the metal when you need to (via JNI, which is a pain, but still); it has
garbage collection. It is perfect: no. Is there any chance that the
flaws will be fixed: no. Or it will take 5 to 10 years of going through
JSR/JCP, corporate struggles and some lawsuits. Fortunately,
people are building some really good things upon the JVM, so
there are alternatives. To make the relevance to Android development

[android-developers] How to set style attribute for progress bar programmatically?

Hi all,

The default ProgressBar is white in color, which will not be visible on

below:

 ProgressBar android:id=*@+id/progress_bar*

android:layout_width=*wrap_content*

android:layout_height=*wrap_content*

android:layout_centerInParent=*true*

style=*?android:attr/progressBarStyleInverse* /



But I need to set the style attribute in my java code after this line.

ProgressBar progressbar = *new* ProgressBar(context);



Please help.

You cannot change styles via Java code. You will need to examine what

those individually.

[android-developers] Problem with Layout with WEIGHT and VISIBILITY params

2011-07-28 Thread Paolo

Hi there!

I have a LinearLayout composed by 4 RelativeLayout. Every
RelativeLayout has the weight params set in order to fill all the
screen. All layouts are set as fill_parent for W and H.

+ LinearLayout
   + Relative 1 weight = 4 (visible)
   + Relative 2 weight = 5 (gone)
   + Relative 3 weight = 5 (visible)
   + Relative 4 weight = 5 (visible)

I want to animate the Relative 3 and 4 and then hide them, so I set
VISIBILITY.GONE when the animation ends. At this point I'd like to
show the Relative 2, which was gone before, so I set it to VISIBLE
So I get:

+ LinearLayout
   + Relative 1 weight = 4 (visible)
   + Relative 2 weight = 5 (visible)
   + Relative 3 weight = 5 (gone)
   + Relative 4 weight = 5 (gone)

I expected that the dimensions didn't changed and that the Relative 2
substituted all the space covered by the others (3 and 4). Instead the
Relative 1 changes its own height... I guess it depends on the weight
params how to avoid it?

Please help me... it's quite urgent!

[android-developers] Re: button id causes app to crash

2011-07-28 Thread DB12

I tried several different id names and none of them worked, but I just
tried my app on a different computer and it worked fine with three
button id's in the dialog (which is what crashed the emulator on my
other one ).  I will try to recreate the problem on the original
computer and post the full log

 You want to just post the full stack trace you get? Particularly the part
 including and after the Caused by line.

 is there a limit to the amount of buttons you can have in a custom dialog?



 No and this does not indicate that would be the problem. Did you try a
 different id other than random?

[android-developers] Openssl for Android (libssl.so and libcrypto.so)

2011-07-28 Thread rickrvo

Hi,

http://android.git.kernel.org/?p=platform/external/openssl.git;a=summary
this is the project that I'm using to try to create a libssl.so
compatible with Qt necessitas target:Android

Since I can't find a already compiled libssl and libcrypto to direct
download... and adb pulling those files from a Android's /system/lib
folder fixes the incompatible libssl.so and libssl.a erros when I -
lssl in the .pro file on my project, but I still get erros like:

as I think it has to do with this similar issue as Ó.Egilsson on his
last post: 
http://groups.google.com/group/android-ndk/browse_thread/thread/74cef4a7d6fec819/cce69b1d4e4dda49
which there errors are supposed to go away if the correct libs are
linked... (as the same code runs perfectly on a linux version of the
application)

So can some one please help me out how to compile these libs? I don't
have a clue on what configurations I need to change in order to make a
successful build... I get stuck in step 3) and 4) of the read me
file...

3) Run:

 ./import_openssl.sh import openssl-*.tar.gz

4) If there are any errors, then modify openssl.config,
openssl.version
   and patches in patches/ as appropriate.  You might want to use:

 ./import_openssl.sh regenerate patches/*.patch

   Repeat step 3.

as well as I don't know what the commands on step 5) and 6) are...
they aren't recognized by my console ( commands m and mm)

Is it possible to find the best-matching resource Programmatically at

For example I have some device that have screen properties that makes
perfect match for layout-normal-mdpi. How can I, at run time, read

normal screen size and for the density mdpi as perfect match. How can
I read this matching at runtime ?

[android-developers] Alert dialog shown but not visible

2011-07-28 Thread Fina Perez

I have an activity where I start the built-in camera using
onActivityResult. After taking a picture, I go back to my application
and show a pop up asking to the user if he wants to take more pictures
or no. It works fine, but after taking the picture, when I press the
save button on the built-in camera app, and inmediatly I press the
home button, If I go back to my application, my activity is visible
but not active and the popup that should be visible is there but I
cannot see it. If I press the back button and cancel the pop up, my
activity is active again, but I dont want to allow the user cancelling
the pop up, so I set my dialog not cancelable. Now, when this extrange
behavior occurs, I cannot use my app, I just have to kill it...

The question is, how can I force to the dialog being always on the top
if it is shown? Cause seems like it is behind the activity, waiting
for the user to interact with it...

Thanks!

I saw this in one of the AndEngine demos.  It's why I'd initially
turned away from it.

In my case, what fixed it was pulling the most recent AndEngine code
via the Mercurial plugin in Eclipse.  Then I built it all from there,
and it ran flawlessly.  So maybe you have the same downloaded version
I'd started with

Hope this helps.

Re: [android-developers] Game made with andengine has weird crashes.

Thanks Jim. the problem comes with three different button press opening app
combinations but it never takes place every single time on a combination.

1) Back button pressed- Crash
2) Home button pressed. Another app opened. Open my app again-crash
3) Home button pressed. Open app - crash

Sometimes the app crashes when you open it.

In all cases except 1 the app shows the crash toast but works fine (in 1 you
exit it anyways). Sometime though my ball sprite disappears.(And no it does
not move of the screen. It simply vanishes.)

Any help?

There us a discussion for this on the AndEngine forums but nothing useful so
far.

 I've had this happen before, typically when refactoring resources and such. 
 Try to Clean your project and then rebuild it, what is happening here 
most likely is that R.java is not getting re-generated correctly so it is 
using the wrong identifier mapping for your button id.   Another example of 
this type of behavior is when you see the wrong images being loaded right 
after you do some renaming of image resources.

2011-07-28 Thread rickrvo


Nevermind step 3) and 4)

I fixed it. If anyone gets this error follow 
http://www.openssl.org/news/secadv_20101116-2.txt
and manually patch the ssl/t1_lib.c accordingly to your openssl
version.

Now the only thing that I can't overcome is the m and mm commands... :\

[android-developers] Error in http request. Status:0

2011-07-28 Thread Shruthi Varma

Hi All,

I am getting this error (Error in http request. Status:0) when I am
trying to load a url in webview in my application.

Here is my code:


webView.getSettings().setJavaScriptEnabled(true);

webView.loadUrl(webUrl);

webView.setWebChromeClient(new WebChromeClient() {

public void onProgressChanged(WebView view, int progress) {

progressbar.setProgress(progress);

progressbar.setVisibility(View.

VISIBLE);

if(progress == 100)

progressbar.setVisibility(View.

INVISIBLE);

}

});

webView.setWebViewClient(new HelloWebViewClient());

webView.getSettings().setBuiltInZoomControls(true);

webView.getSettings().setUseWideViewPort(true);

webView.getSettings().setLoadWithOverviewMode(true);




What am I supposed to do? Please help.

Regards,
Shruthi.

[android-developers] Static Initializers - interdependencies

2011-07-28 Thread RLScott

What happens if I have two classes, each with some static variables,
and some initializer in one class references a static variable in
another class?

the beginning of class A:

  public static ByteBuffer audioInByteBuffer =
ByteBuffer.allocateDirect(Main.bytesPerBlock);

and in the beginning of class Main:

  public static int samplesPerBlock=1024;

Is it possible for the static initializers of class A to run before
the static initializers of class Main, so that Main.bytesPerBlock is
not defined at the time it is used in the initializer of
audioInByteBuffer?

[android-developers] WebView text selection and persistent highlighting dilemma

2011-07-28 Thread IcedNet

Hello All,

I am working on a non-trivial epub format book reader project in 3.1+,
implementing it within a WebView.

I am stymied at the text selection/highlight phase (luckily ? I have
many more operations to polish up and implement).

I can , of course highlight text and use the Clipboard manager in it's
intended role (copy/paste, et al).
The problem is twofold when I attempt to enable persistent text
highlighting within the WebView itself:

1) the ClipboardManager does not (currently) seem well-suited for this
-- I have implemented the OnPrimaryClipChangedListener to capture the
clipboard text and process it within my WebView,  but, being that I
cannot override the System Clipboard ActionBar menu, I receive the
text as would any app, only upon clicking Copy etc...  and the menu,
though nice, is not ours.  I have seen the results of polling the
ClipboardManager.hasPrimaryClip() for it's text as well so I believe
that path is doom-laden  :)

2) I have attempted to use the ActionMode pattern, but overriding
onDragEvent() within my WebView is non-responsive (as in it never
fires) and gives me the dreaded Miss a drag as we are waiting for
WebCore's response for touch down. -- as I am trying to control page
turning/navigation within the WebView (javascript disables ontouch
events) for the obvious reason that it is a book reader, not a
webpage.

As an aside, I notice that Google's flagship Books app, though
pretty, also does not allow highlighting/text selection... with the
splitting of images between pages, we were thinking it might be a
WebView implementation as well  -- just a slight beg for source
code...  only slight, really  :)

If it is not clear from the above, I am wondering how to get control
of the ClipboardManager, or barring that (which I assume I cannot do
as it is a System service), maybe someone can point me in the
direction of a workaround for webcore so cruelly denying Java the
ability to control the world.  I am open to taking complete control of
motion events if need be, but that is so demanding for such a
seemingly simple task as this...  I mean, really, Amazon does what we
want to do in Kindle for Droid...  :)

Thanks for your time!

Peace,
Dan

Read the documentation for this widget. If there is no indication that you
can remove those columns, use another widget that allows for single-value
editing or make your own. It's not that hard.

[android-developers] Installation: Separated Client and Service

2011-07-28 Thread Glen Cook

Hello,

We have an application that consists of a UI and a download-service
that downloads content.

In the future, we would like to:
  1. Share our download-service with other applications
  2. Offer various branded and customised versions of the client
[Would appear as separate downloads in the Android store]

We would like all clients running on the phone to share the download-
service. Android is designed to facilitate thisBUT

If we create 2 package files. How do we handle installations?

Scenario 1: New User
  A new user (without the download-service) installs the client from
the Android market. How do we seamlessly accomplish the install?
(Avoid them installing each package separately)

Scenario 2:
  A user with the download-service already installed downloads another
client. How do we detect that the service is already installed?

Does anyone have any suggestions to simplify the installation process?

Thanks,
Glen

[android-developers] getExternalFilesDir() on Acer Iconia Tab A500

I am getting some error reports that indicate that getExternalFilesDir() 
is returning null on A500 with 3.1. Anyone having similar issues?
From what I understand, external storage on the A500 is simulated, 
so it can't really be unmounted. Plus I'm checking this, and the 
environment is as below:

getDataDirectory=/data
getDownloadCacheDirectory=/cache
getExternalStorageAndroidDataDir=/mnt/sdcard/Android/data
getExternalStorageDirectory=/mnt/sdcard
getExternalStorageState=mounted
getRootDirectory=/system
getSecondVolumeStorageDirectory=/mnt/external_sd

getSecureDataDirectory=/data
getSystemSecureDirectory=/data/system
getThirdVolumeStorageDirectory=/mnt/usb_storage
getThirdVolumeStorageState=removed
isEncryptedFilesystemEnabled=false
isExternalStorageEmulated=true
isExternalStorageRemovable=false


BTW, getThirdVolumeStorageDirectory()? That's doesn't 
seem to be in the API.

I fixed it. If anyone gets this error follow 
http://www.openssl.org/news/secadv_20101116-2.txt
and manually patch the ssl/t1_lib.c accordingly to your openssl
version.

Now the only thing that I can't overcome is the m and mm commands... :

as in:

5) Cleanup before building with:

 m -j16 clean-libcrypto clean-libssl clean-openssl clean-ssltest

6) Build openssl from the external/openssl directory with:

 mm -j16 snod  adb sync system

   If there are build errors, then patches/*.mk, openssl.config, or
   android-config.mk may need updating.

 background shown behind the XML view.  It seems to be like a base
 context menu background or something, but I cannot for the life of me
 figure out how to get rid of it, as it really makes things look bad.

 I figured if I set the window to wrap_content that it would just
 shrink down to the size of the XML and be fine, but it is still
 slightly bigger on the Y, and stretches all the way across the screen
 on the X.  Even if I set the size to exact pixel values, or ones based
 on the pixel width/height of the screen, you can still see the black
 background, and if I do that it also does this weird graphical glitch
 on the side that makes it look even worse.

 If somebody knows of a simple solution to this I'd be really grateful
 to hear it.  Ideally I'd like to fix it without ruining the current
 setup, since it works perfect with older versions, but I'll do
 whatever has to be done to get it done right.

 Thank you.

Doug, may I point you to the JPA API, made by Gavin King and approved by the
JCP, it's based on unchecked exceptions.

Also you can read Clean Code, A Handbook of Agile Software Craftmanship by
Robert C. Martin he talks about the bennefits of using unchecked exceptions
over checked.

I agree with you, this flame war is losing sense, also the original poster
dissapeared years ago.

[android-developers] Re: How to add header in ListFragment?

You can supply your own XML including a ListView. From the
documentation of ListFragment:

ListFragment has a default layout that consists of a single list
view. However, if you desire, you can customize the fragment layout by
returning your own view hierarchy from onCreateView(LayoutInflater,
ViewGroup, Bundle). To do this, your view hierarchy must contain a
ListView object with the id @android:id/list (or list if it's in
code)

This is quite similar to how you do for a ListActivity.

Another option is to skip the ListFragment and use a ListView directly
instead. You only need to use ListFragment if the same list (and
related logic) should be displayed in two different activities.

 Going with A means that I have to initialize every fragment and load

 these fragments to load only when needed - when the user selects their
 tab that is.

 Going with B means that I load the fragments into separate Activities
 for each tab. But I'd like the fragment to be able to reach the
 original parent Activity, not just some shell Activity that hosts
 them in a tab content.

 Am I missing something? Is there a way to manage fragments with

[android-developers] Re: changing listview content in separate thread issue

Doug,

I currently do send a broadcast that notifies that data has been
changed which in the receiver I notify the ListView/Adapter but
obviously that didn't work since I still get the
IllegalStateException.  I'm guessing that it's critical that the
listview be immediately notified and the broadcast doesn't satisfy
that immediate notification requirement.

 The description of your problem kind of sounds like a catch-22.
 Someone needs to tell a ListView something, yet they don't know what
 that ListView is.  Does that sound problematic to you?

 At some point, the thing in your system that has updates for a list
 needs to notify the list itself.  Usually, one would do this through
 the Adapter that backs the list.  You'll need some sort of bridge
 between the two, perhaps a listener type interface or a broadcast.

[android-developers] Re: Curious NPE

You and William F. misunderstood Nikolay: he did NOT say don't use
exceptions; they are a bad idea. He said it was the DISTINCTION
between 'checked' and 'unchecked' exceptions that is botched. He is
not alone in this claim, he is in good company. Even the deservedly
famous Java expert, author and teacher Bruce Eckel says something very
similar, saying, It has been an experiment, which no language since
has chosen to duplicate.

He goes on to explain why the idea looks good in small examples, but
in larger programs it introduces more problems than it solves
(Thinking in Java 3rd ed, chapter 9). But by no means is he against
using exceptions. He is only against the misuse of them that the
distinction encourages, e.g., subverting the exception handling
mechanism by writing 'spurious' code to suppress exceptions.

 No, I'm not, because you're not using logic to address to issue at

   If you are that kind of engineer (and I would argue that you are not

  Java is old. And because it's 'enterprise', it won't change much.
  Checked exceptions is not the only problem with it. So yes,
  when possible, I use more modern alternatives.

 Go on.  I'm listening.  Please don't just say do your own research
 or smart people write about this.

   The whole point is, that with checked exceptions you are forced to
   handle or re-throw/declare them even if you don't what to do that
   *in that particular part* of your code. Nobody is saying 'we will
   ignore all exceptions and keep our fingers crossed'.

   Truthfully, how often do you really NEED to ignore checked
   exceptions?  It does come up, but not enough for me to get upset that
   I have to do it.  For me, it's a few extra lines of code in a few
   places.

  Again, I never said ignore. I said 'don't handle in that particular place'.
  A few extra lines of code multiplied by a hundred places makes for
  a lot code bloat. Don't you just love it when you have to handle
  IOException when calling close()?

 Please answer my question above.  How often?  In my experience (16
 years) it's not common enough to complain about.  There are cases,
 yes, but only on shutdown/termination.  I don't obsess on those
 cases.  I do them one and be done with it.  It takes at most 1 minute
 out of my day.  If you can't spare that 1 minute, then don't use Java.

  We can go on forever, but there's not much point. Have fun with
  your exceptions.

 Please make a case for your alternative.  I'm listening.  Please make
 it relevant to Android development, considering the forum in which
 we're participating.  If you have an axe to grind against Java as a
 language, I suggest you do it elsewhere.

I uploaded a really simple project, in case someone wants to test it
on their devices :D

 Thank you all,

 and setting windowSoftInputModem stateHidden solves the problem. I'm
 still wondering why we should explicitly set this value, is this a
 bug?

 Kind regards,

  I'm able to replicate a unusual issue with EditText. But it doesn't
  happen on all devices.

  Let's say you have the following layout:

  ?xml version=1.0 encoding=utf-8?
  RelativeLayout xmlns:android=http://schemas.android.com/apk/res/
  android
          android:layout_width=fill_parent
  android:layout_height=fill_parent
     !-- ScrollView, GridView, etc also causes this. --
      ListView
          android:id=@+id/listView1
          android:layout_width=match_parent
          android:layout_height=wrap_content
          android:layout_alignParentTop=true/ListView
      EditText
          android:id=@+id/editText1
          android:layout_width=wrap_content
          android:layout_height=wrap_content
          android:layout_alignParentBottom=true
          android:text=EditText/EditText
  /RelativeLayout

  When your activity is created and displayed the first time,
  softKeyboard will be shown even if user doesn't select the EditText
  field.

  I haven't reported this issue on Android trouble ticket system, since
  I think this is an issue on manufacturer implementation (may be)

  Devices we have:
  Sonyericsson Xperia x10 (with Cyanogen 6) - Issue doesn't appear.
  Motorola Milestone - Issue doesn't appear.
  HTC Desire - Issue happens on it.
  LG GX2 (T-Mobile) - Issue happens on it.

  The recipe to replicate this seems to be, having a ViewGroup above
  any EditText, will cause in certain devices, soft keyboard to appear,
  when entering on an Activity.

  I just would like to know if other ppl is able to replicate it, on
  which devices, and if possible, what's the workaround.

[android-developers] How do we get Google's attention regarding the problems around randomly sorting comments in the Android Market?

2011-07-28 Thread BenMc

I think the randomly sorted comments in the Android Market are about
the worst thing that can happen to devs and users.

Right now, comments are showing up on apps across the board that date
back months.  Many times they are negative, 1-star reviews, that refer
to a long out-dated version of the application.  We work HARD to
create great apps and update them based on customer feedback and
Market comments.  But now, all that is in vain as the fruits of our
labors are blatantly ignored in the comment system.

Your Dev Console may still show all the great reviews that come in for
your recently updated app - but since only a random subset of old
reviews show up at the top on your App in the New Market and Web
Market now, it's as if the update never happened.  It's like all the
hard work that was put it didn't matter because it's showing
complaints from really old versions of the app.

There are some simple solutions.

1) Show 3 random comments from the date of the most recent update.

2) Show them in reverse chronological order as they were.

3) Or come up with a far more sophisticated, logical, approach to
displaying comments.  For example, if you have 80% 5-Star ratings, the
top 2 comments should be 2 random 5-star ratings, and if you have 10%
4-Star ratings, the last one should be a 4-star.  At least it would be
reflective of your actual ratings.

4) LOTS of other great ideas are out there.

The question is tho, if others are on the same page as me, how do we
get this issue fixed by Google for the good of Users and Devs alike?

 Hello All,

 get it done As fast as possible wihtout losing the image sizing and
 crispness I had been trying to resolve this problem for last
 couple of days and I am running always to gotchias (The final
 destination of the Image I want it to be in the SDCARD)

 1. I tried writing directly an image to the SD-CARD and it took about
 about 180 msec
 2. I tried writing to internal cache memory first (160msec) and then
 copying using the FileChannel the image to SDCARD (4msec)

 Does anyone know what would be even faster?
 If there is no faster way to do this, that is fine, but I just want to
 make sure that I visited all of the possible ways.

 Thank you all for your help ahead of time.

 Thank you and Best Regards,

2011-07-28 Thread Kostya Vasilyev

Your timings don't seem that bad - 180 ms for approximately 3 MB image 
(you didn't write anything about compression) is about 16 MB / sec.


I'd recommend you run some kind of compression on the image data. It 
doesn't have to be anything fancy that gets you the minimum possible 
image size, but rather the opposite - something that can reduce the file 
size, while taking less time than it will save on I/O.
