That was rich.

I'm not sure why you're upset over such an obvious spam.  Certainly I 
wouldn't worry about it gaining any competitive edge; the whole piece was a 
giant advertisement for why one should *not* use his services. 

If you know this joker, it's more fun to give them advice than to report 
them.  Tell him, for example, that before putting forward a claim of 
"having a good command over english language" that one might wish to learn 
English.

This guy you're worried about is more pathetic than dangerous.  Tell him so.

Re: [android-developers] Layout Height

[Raghav Sood]

1) This is not, strictly speaking, a custom layout.
2) Use wrap_content. That way the layout will scale to the size of your
content. Or use fill_parent, if you want to take up the entire screen, even
if you don't need it.

Thanks

[android-developers] Layout Height

[Siva Prakash]

Hi

I have created custom layout

http://schemas.android.com/apk/res/android";
android:orientation="horizontal"
android:layout_width="fill_parent"
android:layout_height="15dip"
android:gravity="center_vertical"






Here I mention height as a constant value if I put it in small screen
mobile then it will take same space which will be huge . Is there any way
for me to specify the height in percentage or shared?
I tried "weight" that also didnt help me.

You can be pretty sure none of these are removed in ICS.

Generate randomly and use a different one for every encryption.
Then store it with the message and use it initialize the cipher

I came to the same conclusion and already changed all my code catching
checked exceptions.

cipher_algorithm is "AES/CBC/PKCS5Padding"

How should I be generating the IV?

It works on the ICS Emulator.  Had it been a Galaxy Nexus, I would be
more worried, but since it's a Droid X, it has to be something half-
baked at this point, unless it's a Motorola employee testing a build.

with the caveat that i am still in get-going and do not have my
first .apk build up yet it seems rather obvious to me how to do it as
this would be an intermediate level work in Java - if Kyra were here I
would be she would allow passing by reference here

remoteOrBackGroundService(this);

or something like that then on the other end in Java it would
obviously be save this as the type of the class that you are trying to
broadcast from

you have to be really diligent about not creating a circular reference
but compilers by their task should be able to spot those and look for
them in a build as they report circular constructor chains readily

I am still in get-going but those xml files and the way they are using
them sure look like application initialization to me

if they are then you only live once as far as they are concerned.

what they are calling Binders is actually RPC ~ you can do it that way
but is sorta clumsy - not really badly so if you are willing to
construct enough String to pass whatever need be

do not fall for using statics though as that is not the ideal way due
to the way the machine dumps when the user shakes the phone around

what you do is check for nulls and handle so that you do not get
bitten like the other poster who is going to nail the wall on 14 

it's really simple in java - you can ship me some (sterilized) class
names and method names and I can write it for you in Java screwing off
while I wake up and make coffee ~ will trade some GUI stuff for it
with you as I am nimrod on GUI stuff - I do hardcore backend =
gui.equals("fear") returns true in all case, even with the phone shut

I see. ACA 4.x has handleSilentException() which (I think) might work.
You might want to just wrap with RuntimeException instead of
returning null, that way the cause won't be masked.

Anyway, it's either one of NoSuchAlgorithmException, NoSuchPaddingException
InvalidKeyException or InvalidAlgorithmParameterException. It is very
unlikely that they removed an algorithm or padding from ICS,
so that leaves an invalid key or IV. Since your IV seems to be a constant
(bad idea, BTW), that leaves the key. What is R.string.lvl_cipher_algorithm?

If it doesn't repeat, it might be just a broken emulator-based ROM or something.

I just change my code to rethrow the GSE as a RuntimeException which
is caught and reported by ACRA.  So hopefuly, after I update the app,
I will get another report from the same user.

[android-developers] Re: Ice Cream Sandwich -- possible Crypto incompatibility

[Zsolt Vasvari]

I don't know how really.  ACRA seems to only show the last exception,
and unless I propogate the checked exception, I don't seem to be able
to force ACRA to just report the first one.

Answered one of my questions. I changed my simulated device to 164 ppi
and got the 1.0 density. Sorry, this should have been obvious.

[android-developers] Density confusion

[Kim]

I am testing our app on a Galaxy Tab 7 and a Kindle Fire. They both
have the same number of pixels and screen size, but the various views
on the Fire are two thirds the size of the same ones on the Tab.
I put in a couple of lines of code to capture the screen metrics and
find that the Tab is returning 1.5 for density and scaled density and
the Fire is returning 1.0. Also, for densityDpi, the Tab is returning
240 and the Fire is returning 160. This explains the different sized
views, but I don't understand why.
By the way, a simulator set up with 1024x600 pixes and 169 ppi looks
like the Tab.

I do see that the Fire reports back about 165 dpi, x and y, vs about
169 from the Tab. Are they just on either side of the border of Large
and Medium?
If so, is there a way to load the layout-large xml even though the
Fire is on the Medium side?

[android-developers] Ice Cream Sandwich -- possible Crypto incompatibility

[Zsolt Vasvari]

I got the following ACRA crash report:

USER_COMMENT=Working with widget.
ANDROID_VERSION=4.0.1
APP_VERSION_NAME=1.7.0.2008
BRAND=verizon
PHONE_MODEL=DROIDX

So this guy appears to be running Ice Cream Sandwich on a Droid X.
That's my first huh...

The crash seems to come from my LVL code:

private static Cipher createCipher(Context context, SecretKeySpec
secret, boolean encrypt) {
Cipher cipher = null;

try {
cipher =
Cipher.getInstance(fixText(context.getText(R.string.lvl_cipher_algorithm)).toString());
cipher.init((encrypt ? Cipher.ENCRYPT_MODE :
Cipher.DECRYPT_MODE), secret, new IvParameterSpec(IV));
}
catch (GeneralSecurityException e) {
ErrorReporterFactory.getInstance().reportException(e);
}

return cipher;
}

If I get a GeneralSecurityException, I report it, but then I return
NULL which causes an NPE later on, which I saw in the crash report --
instead of the GeneralSecurityException.

Anyway, other than somebody from Google, probably nobody could answer
that, but why would this code suddenly throw a
GeneralSecurityException on ICS when it works fine on HC and earler.
I am afraid, once ICS hits, I will be deluged with unhappy users and 1-
star ratings.

[android-developers] Re: Very weird NPE in onPrepareDialog

[Zsolt Vasvari]

If prepareCongratulationsDialog() is only called once, it will be
merged by ProGuard, so the NPE will be in
prepareCongratulationsDialog() itself somewhere. The line number is
useless.

[android-developers] Very weird NPE in onPrepareDialog

[Emanuel Moecklin]

I get reports of NullPointerExceptions in onPrepareDialog in line 860
(method call to prepareCongratulationsDialog(dialog)):
@Override
protected void onPrepareDialog(int id, Dialog dialog) {
super.onPrepareDialog(id, dialog);
switch (id) {
case DIALOG_CONGRATULATIONS:
prepareCongratulationsDialog(dialog); // line 860
break;
case DIALOG_...:
// some code
}
}

private void prepareCongratulationsDialog(Dialog dialog) {
// some code
};

The dialog is a managed dialog opened using
showDialog(DIALOG_CONGRATULATIONS)

The stack trace looks like this:
java.lang.NullPointerException
at com.company.app.MyActivity.onPrepareDialog(MyActivity.java:860)
at android.app.Activity.onPrepareDialog(Activity.java:2505)
at android.app.Activity.showDialog(Activity.java:2555)
at android.app.Activity.showDialog(Activity.java:2514)
...

I normally can't reproduce the problem (only once so far) and it seems
to happen on arbitrary devices and Android versions but once it occurs
it seems to have a certain persistency (I normally get several crash
reports from the same devices).
How could that line possibly cause an NPE? Even if dialog were null
(which it isn't, I had a productive version that tested against dialog
being null and that didn't help), at least
prepareCongratulationsDialog should be called.
In that case the stack trace would show the line of code in
prepareCongratulationsDialog causing the NPE (tested that as well just
to make sure).
I tried to put a try catch around the method call. What happened is
that the app didn't crash and the dialog appeared but "unprepared"
meaning with all the %1$s etc. placeholders that the onPrepareDialog
is supposed to replace.

If the method prepareCongratulationsDialog itself isn't crashing how
could line 860 possibly cause an NPE?
Could the fact that I'm using ProGuard be related to these crashes?

Any help is very much appreciated.

Re: [android-developers] Re: Capture Video + Circular Buffer for Video on Android

Does gstreamer natively work with circular buffers? In my searches for
circular buffers I have yet to see any references to gstreamer come up.

Is there a particular class within gstreamer I should try to look into?

[android-developers] Re: Multiple Apps and Content Providers, How to ?

[BelvCompSvs]

there are some other things you may not have thought about yet

go to the developer doomawhichythingy at

http://developer.android.com/videos/index.html#v=WGIU2JX1U5Y

and run the video titled

Evading Pirates and Stopping Vampires

about half of which I was already working on and had re-coding of the
LVL entry point for the app well underway like changing the salts for
aes and looking for "chokepoints" that would make an ideas attack
vector and as the speakers were working i had a near-brilliant insight
on how exactly to approach the market correctly

suffice it to say we do not want a legit customer who is trying
getting a block on every app load

standard engineering ~ the correct approach to "licensing" actually
involves a softer approach - you do what you mention in that last post
and these speakers on the google team confirm your approach

[android-developers] Activity can not receive the same intent second time while the app which this activity belongs to launched from another app.

[Cimo Huang]

Dear Android Developers:

I got an issue that activity can not receive the same intent second
time while the app which this activity belongs to  launched from
another app.

I have an app2 launched from app1. Then in app1, start activity B from
the main activity A with  startActivity
The launch mode of B is "Single top"


  

  
  
  


Then I search in B, first time I search, the onCreate in B is called.
Search again, this time B doesn't response the

search inetent, no matter onCreate and onNewIntent, they both haven't
been called. It seems like B is not at the top of

the visiable stack, but I don't know why and how it can be that.
How can I do to make B receive the Search intent in second time?  Here
I can't sdd flag for the search intent and can't

change B's launch mode or add paremeters like "
android:clearTaskOnLaunch="true" " in manifest.
Is there any way to solve this issue? What's the root cause of this
issue. Can you please provide me some suggestion?

Thanks a lot in advance.

Check the documentation, it has an ExpandableListView example.
Get that working.
Then replace the view it returns with a TabView and see if it works.

Java 7 is not officially supported, AFAIK. People on SO have been reporting
this, so I guess it's known :)

SHA256 is the new default in Java 7 jarsigner, so you need to specify the
-digestalg option to use SHA1, as you've found.Don't know if 
even supports specifying the digest algorithm, so you might want to create
an unsigned package and call jarsigner directly from your build script.
Or just use Java 6 and save yourself some trouble :)

Probably a bad idea. A new app will have no apparent connection to
the existing one, and will have 0 users/0 rating. Try to change their
 mind :)

You have basically two choices:

* a full featured paid 'pro' app -- easy. You might have to think of
a way to migrate any data from the free app, and ask people
to uninstall the free app, or make sure they can co-exist
peacfully

* in the current free app, check it the pro stub/license app
is installed, and enable pro functionality if it is. You need
to check if both are signed with the same key too, otherwise
anyone can make an app with that package. Downsides:
people need to have two apps installed, and one of them
does nothing (you can make it a 'shell' that just starts the
original/free app).

due to the type of internet interlocutor i find funny - I flat have no

whether [N] { in-case she reads this } is getting 419's that appear to
be from ->my<- account

I am a straight and at least have the courtesy to go to those places
where that is done rather than bothering innocents

it is my opinion that there is a "vast" cabal who .

how ^exactly^ do you propose we shield our own activity here . ?

we could probably use the work strengthening the security model for

[android-developers] Re: Handster

[Ali Chousein]

Yes it is worthwhile. Cisco chose one of my apps from Handster to
distribute in their app store for example. Based on my experience it's
a serious site.

[android-developers] Google+ and NFC

[Dominik]

can someone (probably from the Google-Guys) explain, why NFC support
has been disabled for the Android Google+ app? With earlier versions
of the Google+ client, a tag with an NDEF-Record of type
TNF_WELL_KNOWN and the type RTD_TEXT ("T") was automatically read in
and pasted into the "post message" form. This no longer works.

Or has the type of NDEF messages changes which are known by the Google
+ app?

Thanks for your help
Dominik

PS I have Google+ build-version 2.1.1.219805 installed

How would we determine what version this was?

They aren't compressed so that they can be mmapped when starting the
process, instead of having to decompress and copy the entire resource block
to RAM.  You really do not want that file compressed.

One thing to look at is that you are building against a the min SDK version
at which the platform switched to UTF-8 for resource strings.

[android-developers] OpenGL on android

[John Goche]

Hello,

I am new to OpenGL and would like to write some
code in it for Android. I wonder whether there are
any significant differences in the android implementation
compared to JOGL http://jogamp.org/jogl/doc/HowToBuild.html
(which also has a quite involved setup process).

I ask because I was thinking of developing in JOGL in order to
speed up the process and then when the project is ready port
the code to android (which has a slower emulator compile,
load, and test development cycle).

Also, would I find a .OBJ (Wavefront) parser anywhere on
android or must I implement/import my own? I ask because
I would require one to read my model into OpenGL/Java.

Comments and suggestions on how to proceed welcome,

Thanks,

John Goche

[android-developers] setting permission...

[Nishit Soni]

I am developing a project which utilizes oauth (client side).
I am unable to retrieve the request tokens.
The error shown in the catlog (eclipse) is : "communication with the
service provider failed : the target server failed to respond"

I think it is because of no permission being set in the manifest
file..
Can anyone suggest how and which can I set permission for this
problem..?

Thanks..

[android-developers] sound spectrum analyzer

[ron simon]

Hi Dev. Team,
I want to create a spectral analyser but I'am new in this field . For
writing a content from a music file in an array I used this

try {
File file = new File(mFileName,
array_spinner[Getposition()]);
 file.createNewFile();
 InputStream  is = new FileInputStream (file);
 BufferedInputStream bis = new BufferedInputStream
(is);
 DataInputStream dis = new DataInputStream
(bis);

while (dis.available() > 0)
{
dis.read(buffer,byteOffset,byteCount);
}
 dis.close();

 //write buffer into a text file

After that I wrote this buffer in a txt file for reading.

Text.setTxtDatei("test",buffer);

The problem is that the content is allways the same for every music
file.So it can not be the buffer of the stream.
So the question is how to get the buffer into the txt file ?

Yours,
Ron

[android-developers] FragmentMap + ActionBar Tab

[m3n0R]

I have a problem I've been trying insert a MapView into a ActionBar
Tab, but I wasn't able to solve the problem even googling...

Here is the Main Activity:

@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
//setContentView(R.layout.action_bar_tabs);
FragmentManager fm = getSupportFragmentManager();
fm.beginTransaction().add(android.R.id.content,
GigLoader.GigLoaderListFragment.newInstance()).commit();

 
getSupportActionBar().setNavigationMode(ActionBar.NAVIGATION_MODE_TABS);

ActionBar.Tab tab1 =
getSupportActionBar().newTab().setText("Geo").setTabListener(this);
ActionBar.Tab tab2 =
getSupportActionBar().newTab().setText("Lista").setTabListener(this);
getSupportActionBar().addTab(tab1);
getSupportActionBar().addTab(tab2);
}

@Override
public void onTabSelected(Tab tab, FragmentTransaction ft) {
if (tab.getPosition() == 0) {
fm.beginTransaction().add(android.R.id.content,
GigLoader.GigLoaderListFragment.newInstance()).commit();
}
else {
fm.beginTransaction().add(android.R.id.content,
GeoGigLoader.GeoGigMapFragment.newInstance()).commit();
}

}

And here the code of the GeoGigLoader:

public class GeoGigLoader extends FragmentMapActivity {

@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
}

public static final class GeoGigMapFragment extends Fragment {

static GeoGigMapFragment newInstance() {
GeoGigMapFragment map = new GeoGigMapFragment();
return map;
}

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup
container, Bundle savedInstanceState) {
View view =
getActivity().getLayoutInflater().inflate(R.layout.map_gigs,
container, false);
MapView mapView = (MapView)view.findViewById(R.id.map_view);
mapView.setBuiltInZoomControls(true);
return view;
}

}

@Override
protected boolean isRouteDisplayed() {
return false;
}
}

FragmentMapActivity is a library from actionbarsherlock.com, and this
one extends from a MapActivity, so it should work...

The error I get, is the next one:

FATAL EXCEPTION: main E/AndroidRuntime(954):
android.view.InflateException: Binary XML file line #2: Error
inflating class com.google.android.maps.MapView E/AndroidRuntime(954):

AndroidRuntime(954): at
android.view.LayoutInflater.createViewFromTag(LayoutInflater.java:565)

Anybody knows what's happening? Thx!!!

[android-developers] Programmatic gallery scroll on a timer?

[noobler]

Hi,

I need to implement a gallery which scrolls one item at a time, and
which can do 'autoscroll': i.e. every couple of seconds, it
automatically scrolls to the next item.
I extended Gallery, overriding onFling to ignore the fling event and
instead simulate a DPAD arrow left or right in order to move a single
item at a time:

@Override
public boolean onFling(MotionEvent e1, MotionEvent e2, float
velocityX, float velocityY) {
  int kEvent;
  if(isScrollingLeft(e1, e2)){ //Check if scrolling left
kEvent = KeyEvent.KEYCODE_DPAD_LEFT;
  }
  else{ //Otherwise scrolling right
kEvent = KeyEvent.KEYCODE_DPAD_RIGHT;
  }
  onKeyDown(kEvent, null);

  return true;
}

This works well.
For the auto scroll, I create a handler and postDelayed a runnable
which simulates the same DPAD key press in the same way:

handler.postDelayed(new Runnable() {
public void run() {
onKeyDown(KeyEvent.KEYCODE_DPAD_RIGHT, null);
}
}, AUTO_SCROLL_INTERVAL);

but this doesn't do anything!! I know the runnable gets executed as
expected at the correct interval, since I logged it and confirmed
this, but the onKeyDown does not cause the gallery to scroll or switch
items.
Why would this work in one method and not another?
I looked into the Gallery code for clues, but found nothing! It seems
as though it should work.
Please, I'm stumped... any ideas?

Thanks

[android-developers] Problem when I add a header to the list of a PreferenceActivity on Honeycomb

[Julien Del Rio]

Hi everybody,

I work on the Honeycomb version.

I add an header to the list in my PreferenceActivity using
getListView().addHeaderView(header).

But now, I think there is a problemn on the index of the list. When I
click on a line, the onPreferenceTreeClick return the previous line.

Do you have an idea for managing this problem ?

If you can reproduce the problem, it seems like a fine issue for
b.android.com, perhaps with a side post to the adt-dev Google Group
about why they aren't compressed by default.

Regardless, my apologies to the OP for my error.

No, sorry, Ms. Hackborn has indicated that nesting fragments in
fragments is not supported. There's a StackOverflow post or two on

[android-developers] Re: Multiple Apps and Content Providers, How to ?

[swebb99]

Right I've had a read around in-app purchasing and I think its the way
to go.

My thinking is I release the initial version of the code probably
without in-app code, just get it out there. Then I do an update when
ready which add in-app purchasing. The extra logic to be bought will
already be in the app just not enabled. When the customer makes a
purchase the extra logic is enabled. Whenever I do updates another
extra bit of functionality maybe provided which may require a purchase
and the purchase screen will have extra entries. Should all work quiet
well I think.

Thanks

[android-developers] Looking for a partner

[Alexander Turda]

I started working on an app and I could really use some help.

All I need is a person with at least 1 released app.
Also,I need that person to be able to work at least 2 hours per day.


The app I'm working right now is unique,I mean there isn't any app like 
this one.
If the partnership goes ok,then I have plans for future...(do I have ideeas 
for future apps? Heck I do!)

Now I would actually need a person to setup an xml reader,and to play a 
little bit with some settings on a listview. I can't do those cause I'm 
working on a service,so a person that knows how to work with that,would be 
awesome.

If you think you can handle all that I wrote above,feel free to contact me! 
(also,please send me the apk or the link to the app you made!)

[android-developers] Re: localization bloats my app - is there an alternative approach?

[Kevin TeslaCoil Software]

Actually in a normal build the resources.arsc file isn't zip
compressed with the other files are and it can be quite large.
Manually running aapt can compress it (and does by default), but then
you get really weird force closes on some froyo devices. I've been
meaning to ask about why this is.

But my advice is not to split the APK and translations. It will create
a lot more work for you and confusion or bugs for users. And phone's
storage space is just getting large.

[android-developers] Fragment within a fragment?

[Doug Gordon]

So Fragment A is instantiated, inflates its view, and goes on its merry 
way. Can Fragment A later instantiate a Fragment B and add it to one of 
Fragment A's own child views, thus creating a sort of fragment within a 
fragment?


I can't think of a reason why not, but still don't have a really good 
grasp on how fragments are implemented and managed. Thanks.

 int pr = (pix << 16) & 0x00ff; 
 int pix1 = (pix & 0xff00ff00) | pr | pb;

Try swapping the red and blue channels:
 int p*r* = (pix >> 16) & 0xff; 
 int p*b* = (pix << 16) & 0x00ff; 
 int pix1 = (pix & 0xff00ff00) | pr | pb;

[android-developers] Problems when signing APKs with Java 7.

[BoD]

Hi!

I just spent a few hours on a signature problem when building our project 
with ant on a machine that has (Oracle's) Java 7 installed.
When trying to install this apk, I have this error: 
Failure [INSTALL_PARSE_FAILED_NO_CERTIFICATES]

After looking inside the MANIFEST.MF file inside the apk, I noticed that 
the digests are in the form:
SHA-256-Digest: tXIm+feek/QDGP6yrxtgWDHyfl+XaND6lXbsY9gjZrA=
Whereas when building with Java 6, they have the form:
SHA1-Digest: lPHIYoqZ+2OpY0LPumyDkUdNdoc=

I then saw in the (Java 7) jarsign documentation the -digestalg options 
(http://download.oracle.com/javase/7/docs/technotes/tools/windows/jarsigner.html).
When signing manually the apk with jarsign (instead of using the ant 
build), and passing -digestalg SHA1, I no longer have the problem.

I was wondering if this was a known issue, and if yes, is there anyway to 
fix it in an 'ant friendly' way?

Thanks a lot!

[android-developers] International / UTF-8 bug in java.util.zip

[Lathe26]

I have found the following bug in Android.  Where do I report it?

There is a bug in java.util.zip (likely in the ZipEntry class) where
the name of the ZipEntry is not properly encoded in the ZIP file.
This bug affects any UTF-8 characters that are not in the ASCII
range.  An example character is the '©' character, which is Unicode
codepoint 0x00A9 or in UTF-8 is 0xC2 0xA9.

The effect of this bug is that file names that contain non-ASCII are
read back with corrupt file names by other ZIP file reading programs
(ex: PKWare's PKZip or WinRar).  Thus, file names that contain
international characters or special symbols are being corrupted.

What is happening is as follows:
1.  By default, ZIP files contain file names that use the IBM 437
character set for historical reasons.  To use the modern UTF-8
encoding of the Unicode character set, a flag needs to be set in the
zip file.  This flag has been supported since ZIP file format version
6.3.2 which was released in September 2007.
2.  Android writes file names in UTF-8 format but does NOT set this
flag.
3.  What appears to be happening is that the flag field is a 16-bit
field that is stored in little-endian format.  The flag to be set for
UTF-8 support is bit 11.  Instead, bit 3 is being set.  Bit 3 is
documented by PKWare to mean "...fields crc-32, compressed size and
uncompressed size are set to zero...".  However, since the crc-32 and
size fields are not 0, I am guessing that the Android code is _trying_
to set bit 11 but is doing it in incorrect big-endian format and thus
accidentally setting bit 3.

For debugging / testing purposes, I used a hex editor to properly set
bit 11 in the zip file.  This enables other ZIP file reader programs
to properly decode the file names.  I have 2 example ZIP files, before
and after this hex edit, that demonstrate this bug that I can make
available.

Note: do not rely on Microsoft Windows 7 built-in zip reader program
for testing purposes to properly decode the file names since
Microsoft's implementation is known to have several zip-related bugs.

Re: [android-developers] Speed up dalvikvm calls

[New Developer]

Thanks Daniel

Iam trying to call it every 5ms  But I would settle for as fast as possible.

I have tried so somehow buffer, thus trying to do all the I/O first and 
then just view
but this has failed hopelessly I can only load 15 frames into memory and 
then get an OutOfMemory


Do you by any chance know how to find the bandwidth of the Xoom and Sony 
S bus what is it capable of
If I have to call every 20ms  but get a smoother flowing video playback 
that would be fine.


It's just right now I read every 327  or 327000  frames
frame is not incremented by 1 but by 327  this works for the timing it 
now takes 15 sec to play a 15 sec video
BUT you are skipping so much that it is obviously  jerky and does not 
flow.  Would love to

increment frame by 10, but then then the handle cycle to be faster.

any ideas ?

thanks in advance

How often is this code called? Do you know, that retriever does I/O to

Are you trying to have it running every 5ms?

Do you appreciate that 1280 x 720 x 4B = 3.5MiB and if you want that
every 5ms, then your I/O bus and memory bus would have to have
bandwidth of 700MiB (assuming processing takes zero time in the 5ms
slot, which obviously it doesn't).

That is a big ask for any mobile phone.

[android-developers] Please Help with GPS Provider Switch

[Tommy Hartz]

 

Hey,

 

Right now when trying to get a user location I start with the GPS Provider.
I have a timer set for 30 seconds, If a location is not found in 30 seconds
the timer goes off and stops that location request. When that happens I move
to the Passive Provider. After 30 seconds if a location is not found I stop
the location request and move to the Network Provider.

 

My issue is that when the network provider gets called it never does
anything. If I start with the network provider it goes off just fine and
returns a location back to me. Below is the code I am trying to use:

 

gpsTimer.schedule(new TimerTask(){

  @Override

  public void run() {



startPassive();





  }

}, 3);



currentTimer = "GPS";

 
locationManager.requestLocationUpdates(LocationManager.GPS_PROVIDER, 0, 0,
locationListener);

 

private void startPassive(){



locationManager.removeUpdates(locationListener);



//Now we want to try for a Passive Fix

currentTimer = "Passive";

passiveTimer.schedule(new TimerTask(){

 

  @Override

  public void run() {

startNetwork();

  }

  

}, 3);

Looper.prepare();

Looper.myLooper().quit();

 
locationManager.requestLocationUpdates(LocationManager.PASSIVE_PROVIDER, 0,
0, locationListener);

 

private void startNetwork(){

locationManager.removeUpdates(locationListener);

currentTimer = "Network";

Looper.prepare();

Looper.myLooper().quit();

 
locationManager.requestLocationUpdates(LocationManager.NETWORK_PROVIDER, 0,
0, locationListener);

 

any help or suggestions would be greatly appreciated. Thank so much in
advance.

Guess you could be right, Perhaps shifting all the sensor code to the newer

Re: [android-developers] Sensor events are received, but not working.

[Mark Murphy]

It might be a combined bitfield, since they have a TYPE_ALL. Beyond
that, no clue.

So, you added 1.5MB of space with 12 languages. That's around 100KB
apiece. Since this stuff should be compressed in the APK, that's
probably close to 1MB of strings per language.

Hence, the solution would appear to be: make a less wordy app... :-)

Seriously, how big are your string.xml files?

[android-developers] In-App purchase and a Paid entry (2 separate listings on android market)

[androidmediadeveloper]

Anyone encounter a situation where you had to place an app, with in-
app purchasing to pro as well as yet another "paid" entry on the
Android Market ?

We currently have a free app with an upgrade to pro option available
via in-app billing, and the product team wants to create more
"discoverability" for the app by asking for another entry in the
market as a "paid" app.

Any suggestions ? Can this be done with some sort of a stub apk ?
Also, how to treat situations where the free app might already exist
on the device.

Thanks !

Thanks for the suggestions there Kostya, we're going with a issue
refund after purchase approach in lieu of anything in the platform.

Re: [android-developers] Speed up dalvikvm calls

[New Developer]

Thanks to all

It is a video player   I'm using the MediaMetadataRetriever  so that I 
can load and if necessary stop and edit a bitmap


I've tried (obviously unsuccessfully to read the bitmap and make it 
smaller  (for the purpose of memory)
the original video is 1280 x 720  I was trying to save this as a  320 x 
180 bitmap  so as to use up less memory


mBitmap  = 
Bitmap.createScaledBitmap(retriever.getFrameAtTime(frame*1000) ,  320 , 
180 , false);

Item.setImageBitmap(mBitmap);//1280 x 720
mHandler.postDelayed(buffering, 5);
The quality drops radically  which is NOT good,


As it is I'm reloading into the same variable mBitmap the same size each 
time just basically a different set of pixels
What is the best way to setup the mBitmap variable that I keep using the 
same variable and the same memory  ?
I feel that this is deleting the old bitmap from memory then loading the 
new one.

So like a accordion   add,delete,add,delete,add,delete


Is there a way to expand the memory that this application  can use ?  
obviously there is going to be a limit (other apps running and the total 
memory found on the tablet)


Thanks  again to all

Short answer: no.

Longer answer: this probably means that your app isn't written well
enough (or you just need a lot of memory..)

[android-developers] My camera preview height is smaller than the pictures height

[saex]

When i am showing the camera preview i can see a height,  and when i
make the photo, the photo shows more height than the preview. I mean
that i can see objects than i can't see on the preview.

How can i solve it?

THese are the parameters of my camera:

public void surfaceChanged(SurfaceHolder holder, int format, int
w, int h) {
if (mPreviewRunning) { //stopPreview() will crash if 
preview is not
running
camera.stopPreview();
}
Camera.Parameters p = camera.getParameters();
p.setPreviewSize(w, h);
p.setPictureSize(1024, 768);
camera.setParameters(p);
try {
camera.setPreviewDisplay(holder);
} catch (IOException e) {e.printStackTrace();}
camera.startPreview();
mPreviewRunning = true;
}

There should be a TURBO option in the phone somewhere.

But honestly you creating 1.8MB of garbage (dereferenced objects) 3
times within each second, so your GC runs like crazy.

Things to look at:

 - Avoid repeated string concatenation
 - Pre-size your collection data structures
 - Keep caches of frequently-used values rather
   than reallocating them
 - Eliminate references to objects promptly when
   you no longer need them.

[android-developers] localization bloats my app - is there an alternative approach?

[mot12]

My app was about 1.5M, after adding 12 languages I am now looking at
3M because of the multiple string.xml files in the resources. Yes,
they are big but it only became a problem after adding all these
languages. And I want to add more languages...

Does anybody have an idea of how to localize with more awareness to
bloat?

These are the strategies I can think of. They all require some serious
work to put into practice:

1) Split the apk
- Create several language apks to reduce bloat.
- Make the existing apk people paid for just a license apk.
- The individual language apks are free in the market but will not
work without installation of the main apk.
Contra: one has to maintain several apk files

2) Download additional resources
- The apk contains only enough translations to instruct users to
download full language packages of their choice.
- The language packages downloaded onto the SD card (simple xml files)
- The app loads the xml file and creates its own table of resource
strings which is used instead of R.string.
Contra: This adds to the load time of the app if the string.xml is
really big.

Any other ideas?

Thanks for your input,
Martin

Re: [android-developers] After adding JAR file , getting error "Conversion to Dalvik format failed with error 1"

[Kristopher Micinski]

Try rebuilding your project, do a "clean" in eclipse or "ant clean" at
the terminal.  This usually fixes it.

[android-developers] keywords

[bob]

Here is my top-secret business strategy:

Look at my top-performing apps in Android Market.

See what keywords they use.

Create more stuff with those keywords.

However, I can't find the keywords for my apps.  Are there no explicit
keywords for Android Market?
