[android-developers] Re: Avoid non-static inner classes in an activity?

After thinking I made a major breakthrough by stopping that thread, I
still find that Activity Instances stack up.

I'll still need to analyze all the inner classes.

[android-developers] PopUpWindow not displaying when tapping on marker

[Nithin]

Hi,

I am displaying google map and on top of that some overlay
items(Markers) are there. When tapping on the markers, I need to
display PopUpWindow. The code is executing but popup is not
displaying.

popUp.showAtLocation(layout, Gravity.TOP, 0, 0);
popUp.setFocusable(true);
popUp.setTouchable(true);
popUp.setOutsideTouchable(false);
popUp.update(0,50, 320, 70);

Here layout is an object of LinearLayout.

I created another android application, in that, I put the above code
and its working perfectly. PopupWindow is displaying.

[android-developers] Re: Avoid non-static inner classes in an activity?

[Nathan]

While my inner classes could be wrong, I have a bigger suspect.

It seems one of my custom views has a background thread that waits for
work requests and communicates back through a handler. When the
activity ends and restarts, the thread is still alive, waiting for a
work request. Since that thread references a Handler, which references
a View which has a context, so the activity stays alive even as a new
one is created.

I believe what I should do is in MyActvity.OnDestroy, propagate the
message down the chain such that the worker thread exists gracefully.

I suppose I should also make it a daemon thread - since it is one, but
that will only help when the process exits and not when there are
other activities or services running.

Re: [android-developers] how to filter the objects (addresses) to display only the onscreen objects on map

Since I just happen to have written code for this recently, I don't mind

[android-developers] Emulator and cellular access

[Demetris]

Hi all,

  I think the Android emulator has the capability to emulate incoming
phone calls but I am wondering if there is a capability to place 
outgoing calls to
existing cellular networks through the appropriate hardware interface. 
Is there any

documentation of such a functionality I look into?

Thanks

I think you're ready to write some code, since I can't really answer
your latest questions without writing code. I hope you're familiar
with Android logging and Eclipse debugging, because they make it so
much easier to see what's going on in your code. Good luck!

[android-developers] Avoid non-static inner classes in an activity?

[Nathan]

Since I seem to have caught two activity references in a heapdump,
where the Activity is set to singleTask.

Romain's advice on avoiding memory leaks includes:

"Avoid non-static inner classes in an activity if you don't control
their life cycle, use a static inner class and make a weak reference
to the activity inside"

What does this mean exactly? I can't find any examples, positive, or
negative for this rule.

I do have some non static inner classes in my activity.

Most of them are anonymous inner classes like this one. I see hundreds
of them in the samples:

button.setOnClickListener(new Button.OnClickListener() {
public void onClick(View v) {
progressHorizontal.incrementSecondaryProgressBy(-1);
// Title progress is in range 0..1
setSecondaryProgress(100 *
progressHorizontal.getSecondaryProgress());
}
});

Are anonymous inner classes okay?

I also see something like this in the samples:

private OnClickListener mStopRepeatingListener = new
OnClickListener() { . . .

Are member variables points to a non static anonymous inner class
okay? I might think so because a member variable's lifecycle is
controlled by the activity's lifecycle.

Or do I assume that all the API samples leak a lot of contexts?

Thanks for any insights

Nathan

[android-developers] Re: ScrollView and programmatically scrolling

[Lance Nanek]

There are past threads on this you can dig up. Basically you have to
give the ScrollView a chance to realize it has had stuff added to it.
For example:
scroll.post(new Runnable() {
public void run() {
scroll.fullScroll(ScrollView.FOCUS_DOWN);
}
});

[android-developers] Re: java.lang.OutOfMemoryError: bitmap size exceeds VM budget

[Nathan]

Are any of those tools helpful with bitmaps?

I've analyzed an HPRof where all the bitmaps are taking up32 bytes.
that would be nice if it were true. I know that bitmaps are not on the
regular heap, so the tools don't seem to find them.

Since the bitmaps are marked as purgeable, they could be taking only
20K bytes, or as much as 256K bytes, so there is a wide range.

[android-developers] SQLiteCursor on that has not been deactivated or closed

[gcstang]

I've followed the try/finally approach but still get this error.

Is there anything else that can be done?

Here is what I have.

MediaDbAdapter mDbHelper = null;
Cursor c = null;
try {
mDbHelper = new MediaDbAdapter(ctxt);
mDbHelper.open();
c = mDbHelper.findByX(data.getX());
if(c != null) {
   //Do an Update on the database
}
else if(c == null) {
  //Do an Insert on the database
}
} finally {
if(c != null) {
c.deactivate();
c.close();
c = null;
}
if(mDbHelper != null && mDbHelper.isOpen()) {
mDbHelper.close();
}
}

[android-developers] Re: I've found a way to stop piracy of my apps

[keyeslabs]

Biggest issues that I've seen for my own apps (and those other brave
souls who use AAL) have been related to legitimate users that somehow
can't validate their purchase.  For example:

1. user buys app on marke using a 2.0-based phone.  validation happens
just fine.
2. user backs up app, flashes rom to as-of-yet unreleased 2.2, and
restores app
3. Upon startup of the app on the newly-flashed phone, AAL properly
detects the missing license.
4. AAL fails validation, since 2.2-based devices can't "see" paid apps
on the market since Google hasn't registered that release in the
market database.

Other fringe scenarios similar to this.  When I deployed AAL into my
apps, I had a few loud complainers that has tapered off now and I
don't really have any serious problems.  I now get a lot of emails
from people in countries that can't buy from Android market.

Overall, AAL seems to be working quite well.

Lately I've been wondering if there's a way that I can offer the user
an "alternative" mechanism for purchasing the pirated app.  For
example, I upload to Android Market, pirates post on download boards,
others download, and then when validation fails offer to let them buy
from PayPal and license things that way.  I don't think that would
break any of the Android Market rules (since the pirated version isn't
being "distributed" by the market -- it's being distributed by a
pirate board), and it sure would open up distribution to markets that
Google doesn't currently serve.

[android-developers] Supplying your own custom sqlite library

[goosedroid]

I need some features of sqlite which are not compiled in the supplied
version: the R*Tree module and histograms used in query optimization
enabled by SQLITE_ENABLE_STAT2.

I would like to know if it is possible to bundle my own version of
sqlite with these things enabled, and still use the existing
android.database.sqlite.* bindings. If so, what are the general steps?

I am not looking to replace the existing version of sqlite on the
phone which all programs use; I just need a local version specific to
my app.

Not an ordinary SDK application. Whether or not GPS is enabled is a
so-called "secure setting" (Settings.Secure), which cannot be modified
by ordinary SDK applications.

You cannot turn GPS on if it is disabled. Think of enabled/disabled as
a lock, controlled by the user, which determines whether or not
applications even have an option to use GPS.

[android-developers] Re: switching GPS on and off

[RichardC]

Hope this is some help, 2 use cases:

Case 1 - starting with the GPS not enabled in the device settings
  User enables the GPS --> GPS is now enabled but not active
  Application uses the GPS --> GPS is now active
  {GPS things happen}
  Application stops using the GPS --> GPS goes back to not active

Case 2 - starting with the GPS not enabled in the device settings
  Application uses the GPS --> GPS does NOT become active
{errors}
  Application stops using the GPS --> no change in GPS state

Thank you for your help Bhavesh. My question might have been vague.
What I am trying to do is get the auto correct text to show above the

shows in EditText but not AutoCompleteTextView.  I am wondering if
what I am trying to do is impossible or if I should attempt a work
around.

[android-developers] Re: switching GPS on and off

[kamiseq]

once again, maybe it is too much sun over here :)

1. gps is on (powered, whatever) when some app tries to obtain
location info
2. gps is off if there is no app looking for location
3. you then said that
"For example, HTC Sense phones have a home screen feature that looks
like an on/off switch for GPS. That, however, controls whether GPS is
enabled."

so there is some other state that gps can be in and it can be
controlled by application. and yes I dont really understand the
difference between on and enabled.

[android-developers] Video plays audio after device sleeps (OS 2.1 only)

[Mark Nuetzmann]

To replicate:

1. Play any video with audio.
2. Put the device to sleep using the hard key (varies by device).

Audio for the selected video will start playing after a few seconds
while the
device is asleep.

I am calling VideoView.pause() in the onPause() of the activity and
VideoView.stopPlayback() in the onStop() of the activity.  This does
not happen prior to the 2.1 SDK from all our testing but in 2.1 it now
appears to happen almost every time.  We have tested this on the moto
DROID and the Google NexusOne.

Any ideas would be VERY welcome.

Re: [android-developers] Two way contact sync

[Dmitri Plotnikov]

There is no conceptual difference between a one-way and a two-way sync.  My
understanding is that most people start the sync by sending local changes to
the server and then get incoming changes.

The DIRTY column on RawContact will tell you what changed locally.  Make
sure you reset the flag after the changes have been successfully sent to the
server.

You can use the Exchange sync as a source of inspiration.  Unfortunately,
it's crazy complex (out of necessity). Still you may dig up some copy/paste
opportunities there, e.g. the "commit" method:

http://android.git.kernel.org/?p=platform/packages/apps/Email.git;a=blob;f=src/com/android/exchange/adapter/ContactsSyncAdapter.java


Cheers,
Dmitri

[android-developers] Should I bother with my own sync adapter?

[Connick]

In my current app I decided to integrate into account management and create
a sync adapter. I'm wondering if it's worth doing this over an alarm manager
approach as I don't believe it's supported below 2.0? Even worse I'm
currently using a 2.2 API to set the sync interval (not possible before ??)
which is definitely a problem! Also the users accounts have no contacts
associated with them so at times my account type shows up in dialogues that
aren't really applicable.

Sounds like I've answered my own question but I'm curious to hear other
perspectives.

Stace

[android-developers] Two way contact sync

Hey,

I'm developing an application that needs a two way sync of its own
custom contacts. I saw the sample code on Android developer website
(talking about AccountManager here and the sample sync adapter code),
but that only syncs from the cloud to the device. Is there a way to do

this?

[android-developers] MarkerClusterer for MapView

[tansaku]

Hi All,

I've just been playing with MarkerClusterer in the Google Maps API.  I
love it.  Fantastic way to handle large numbers of Markers in a map.
An example here:

http://google-maps-utility-library-v3.googlecode.com/svn/tags/markerclusterer/1.0/examples/advanced_example.html

Does anyone know if there are plans to support this kind of thing in
an Android MapView?

Many thanks in advance

[android-developers] setContentView of a Custom View

[Matt M]

Hello,

My current painting activity is built off of FingerPaint.java from the
API Demos. In my xml I declared the custom view, see below. When I
setContentView(view); everything works fine, but the problem is when I
setContentView(paint_layout.xml) it does not work properly.

///PaintActivity///
public class Paint extends PaintActivity implements
ColorPickerDialog.OnColorChangedListener {

 private Paint mPaint;
 private PaintView view;

 @Override
 protected void onCreate(Bundle savedInstanceState) {
 super.onCreate(savedInstanceState);
  view = new PaintView(this);
 setContentView(view);

 //Set mPaint code
 }

 public class PaintView extends View {
 //PaintView code
 }
//Paint code
}

///paint_layout.xml///
http://schemas.android.com/apk/res/
android"
android:id="@+id/paint"
android:layout_width="fill_parent"
android:layout_height="fill_parent">






Can anyone inform me of why exactly? Am I missing an attribute for the
custom layout in the xml?

Thank you!

Matt.

Are you trying to create the dialog/toast on your UI thread? If so,
they won't appear if that thread is busy; you need to launch another
thread for them. Or preferably, move your long-running process (the
one that needs a progress indicator) from the UI thread into the
background, and keep the UI thread for the UI. That'll also help you
avoid app-not-responding errors.

It means "don't do this."  That means "this won't work," or at the very

are very obviously using private APIs in it."

You don't know what that interface may look like.  The standard open-source

they'd like.

Re: [android-developers] Thread Problem

[YuviDroid]

In your thread you probably have something like:

public void run () {
while (true) {
doSomeWork();
}
}

what you need is a boolean var that checks whether to continue 'doing work',
or stop the thread. Like this:

public void run () {
while (!stopThread) {
doSomeWork();
}
}

Then, when you want to stop the thread, set stopThread to true.

Any idea?

And nothing is showed.

If is useful, the application is a widget.

Re: [android-developers] java.lang.OutOfMemoryError: bitmap size exceeds VM budget

[Sebastian Roth]

Yup. We've been running in that case too many times.
Invest in a good tool like Yourkit, use HPROF Heap dumps to find the objects
with the sticky connects to JVM root and prepare to spend nights on trying
again and again..

I recommend writing automated Unit-Tests for that as well. So that you can
call certain activities 100 times and see whether they retain in memory or
not. Very helpful for us.

Also check basics like background pictures can be encoded as JPG instead of
PNG to save some memory...

Re: [android-developers] Re: Making the Java assert statement work

[Frank Weiss]

I think most Java programmers use Exceptions or logging instead of
asserts. The philosophy is that your code should always be able to
gracefully handle any "impossible" condition.

The great advantage of Exceptions is they can be caught and handled by
your code, re-thrown with wrapper Exceptions, and they can propagate
up the call chain. The downside is you need to code them
intelligently. I won't go into all the details here, and a good Java
book would do the topic better justice than I.

Logging usually provides a better time-sequence context for
exceptional conditions.

Additional code quality tools are unit tests and a good IDE with
debugger (I always get a kick out of debugging Java servlets with
Eclipse).

Re: [android-developers] what is the better application to implement XML program

I suppose you are asking for a recommendation for an XML parsing

Which one is better? I think you can understand that means better for
what. So you have to tell us what you're trying to do. Or you can do
some research on the web to understand the pros and cons of the
different XML parsing technologies.

[android-developers] How to interrupt a blocked URLConnect call?

I'm having issue when I'm trying to connect to a url and it takes
longer than expected.  My code tries to close the connection but
sometimes it is blocked by the URLconnection connect call.  The block
happens even before I can get my InputStream.

What are good ways to stop the request fast without waiting for the
timeout set for the connection?

[android-developers] Re: Repackaging Android System Classes in an application

[Greg Giacovelli]

I understand "don't do this"...  trust me I don't want to, but it
doesn't answer the question if it will work in a market app.
The rationale behind it, is that the rendering implementations between
1.5 and newer versions forward have a minor change with a large impact
with regards to Z ordering. Since bug fixes aren't back ported there
needs to be some way to intercept the call and correct it. I
understand it's fragile however it's only meant to support 1.5, which
as much as it gets neglected, still has a decent amount of people
using it. We use a wrapper around WindowSession to correct the Z
ordering on calls to relayout().

Again, trust me, the fragility is known. However a better rationale
is, that when this app, that as you said "will likely break," ...
breaks, it would be assumed that support for the broken version of the
OS would also be dropped ;)

[android-developers] Re: usb driver mytouch slide

[dlugolinski]

All you need to do is open the android_winusb.ini file that is in the
drivers folder of the SDK. then add this to the file

;MyTouch Slide
%SingleAdbInterface%= USB_Install, USB\VID_0BB4&PID_0E03
%CompositeAdbInterface% = USB_Install, USB\VID_0BB4&PID_0E03&MI_01
%SingleBootLoaderInterface% = USB_Install, USB\VID_0BB4&PID_0FFF

then reinstall the driver for your device

The user does that (e.g., via the Settings application). Your code

[kamiseq]

ok, so if I have a widget on my desktop on the phone and gps is switch
off (dispabled) how should I "enable/disable" it. I couldn't find
anything on that.

the other thing is that when I use ddms to fake gps and I send long/
lat-d manually my location listener is telling me that for first time
status is temporary unavailable then it is available but no updates on
positions comes as I click. is it a bug or feature. I need to try this
in my phone.

Don't use custom Parcelables in Intents used with alarms. Whatever you
are putting in the Parcelable is hopefully backed by a database or
other persistent storage. If so, put the key to the data in the Intent
as a primitive extra (e.g., string, integer), and load in the rest of
the data as needed.

Yes, docu sucks big time there, no bock even has examples how to do
this!

Any way to go around this ? If tried to set the ClassLoader like this:

@Override
public void onReceive(final Context context, final Intent intent)
{
intent.setExtrasClassLoader(Alert.class.getClassLoader());




Now i get new exception output (first line):

I've seen mention of this before on this list. IIRC, Android attempts
to de-serialize the Parcelable inside the AlarmManagerService, and it
does not have your class in the OS, just in your process. Hence, the
operation fails.

[android-developers] Unmarshal Parcleable in Broadcast Reviever

[mac-systems]

Hello,

anyone can point me why i get alway a ClassNotFoundException in my
BroadcastReviever using a custom Parcleable ?

I enqueue Alarms, which trigger the BroadcastReciever:

for (int i = 0; i < alertsToEnqueue.size(); i++)
{
final Alert alert = alertsToEnqueue.get(i);
final Intent intent = new Intent(_context,
AlarmBroadcastReciever.class);
intent.putExtra(IntentConstants.ALERT, alert);

intent.setAction(IntentConstants.DE_MACSYSTEMS_WINDROID_ALERT_TRIGGER);
final PendingIntent pendingIntent =
PendingIntent.getBroadcast(_context,
REQUEST_COUNTER.incrementAndGet(),
intent, PendingIntent.FLAG_ONE_SHOT);

alarmManager.setRepeating(AlarmManager.RTC_WAKEUP, now +
INITIAL_DELAY, (10L * 1000L), pendingIntent);

if (Logging.isLoggingEnabled())
{
Log.d(LOG_TAG, "Enqueued Alert " + 
alert.toString());
}
}

[android-developers] Re: bug with notifyDataSetChanged() in ArrayAdapter ?

[Christophe]

Shink, thank you for your answer.

the add() and insert() work as expected.
However it is a lot easier for me to manipulate directly my ArrayList
(it is more flexible and the ArrayAdapter API lack some methods). I
think I will keep my current code with the overrided getCount() method
so I don't have to add to code to keep the ArrayAdapter in sync with
my ArrayList.

Re: [android-developers] Problem in stopping thread

[Olivier Guilyardi]

I personally do that kind of thing:

class MyThread extends Thread {
  private boolean done;

  public void run() {
while (true) {
  synchronized (this) {
if (done) break;
  }

  /* do a small part of the heavy work */
}

/* cleanup, close files, etc.. */
  }

  /* Call release() to stop/cancel */
  public void release() {
synchronized (this) {
  done = true;
}

/* Wait for run() to return */
try { join(); } catch (InterruptedException e) { }
  }
}

[Christophe]

myArrayList is a simple ArrayList :

ArrayList myArrayList = new ArrayList();

which I give to my adapter in my ListActivity :

adapter = new StepItemAdapter(this, myArrayList);
this.setListAdapter(adapter);

Later I add item to my list and try to refresh the view :

myArrayList.add(position, new Step());
adapter.notifyDataSetChanged();

The flg=0x4 is the set of flags on the Intent in the PendingIntent. I
think 0x4 is FLAG_FILL_IN_CATEGORIES.

The 142 alarms is the number of times this alarm was fired, near as I
can tell. The 51759ms running is the aggregate time spent in
onReceive(), again, near as I can tell.

Re: [android-developers] Problem in stopping thread

[Abdul Mateen]

Hi,

Thread.stop() and destroy were risk in the Threading class. the method I use
to stop thread is to use return; statement where I want to stop the thread.

like

new Thread ( new Runnable() {

 public void run(){
if ( condition ) return; // this will stop the thread.
}

}).start();

Re: [android-developers] power manager (Light off) in android

[Richard C. Cox]

Hi Nandan,

  I think it's impossible to do...maybe it's possible on a rooted phone, but 
that's not what I'm after.  Maybe it will be possible in the future, with 
Gingerbread.  It appears to be something that only apps with Google's 
signature can access.

  On that quote you have from my previous message, I was just wondering if 
running the app from the emulator (rather that going through the normal 
install process) somehow was bypassing some important part of the the phones 
security process.  But, it's clear it isn't.  You are testing on a real phone 
and have the same issue.

Regards,

Richard

RE: [android-developers] How to launch browser from wallpaper?

[Ericson, Anders]

Hi,

Doing 
Activity activity = new Activity()
is probably not a good idea.

instead, get the application context from the wallpaper:
getApplicationContext().startActivity(i);

That will probably work better.

[android-developers] Re: bug with notifyDataSetChanged() in ArrayAdapter ?

[Christophe]

by "overriding the default ArrayAdapter" I mean overriding the
getView(), getViewTypeCount() and getItemViewType() methods.
This is the recommended way of changing the ways the items are
displayed according to the javadoc, so I guess it should not cause
problem :

"To use something other than TextViews for the array display, for
instance, ImageViews, or to have some of data besides toString()
results fill the views, override getView(int, View, ViewGroup) to
return the type of view you want."

Anyways, I have tried to remove all my overrided methods and the
problem is still there ...

[android-developers] Re: Android finishActivity()

[UD]

Hi Mike,

Yes I have done similar thing earlier. And it surely works.
You should have missed some entries in Activity, manifest, styles etc
for making the Activity background blur/translucent.

I have created a demo project to demonstrate this. Tell me how can I
send u the project. mail or some web upload?

[android-developers] Misplaced Layout after “home ”-button and/or powersave screen

[MobDev]

Hi, I have an app which also includes a service with a Notification.
Right now I am experiencing the foillowing problem :

* I start my app which will work fine
* after couple of minutes the powersave kicks in and I get a black
screen
* I (or hte user) click the Menu-button to dismiss the black
screen and to unlock the screenlock
* Now my (fullscreen) app will have "moved" like 30-40 pixels
downwards, creating an ugly black border or hole. When I move the
scrollwheel it will move up and down, and when I press the Menu button
(showing my ap''s menu) it will "fix" the view...

or

* I start my app which will work fine
* I press the Home button exiting the app, my service though will
(correctly) keep running
* when selecting my service from the notification-bar I will get
once again : -Now my (fullscreen) app will have "moved" like 30-40
pixels downwards, creating an ugly black border or hole. When I move
the scrollwheel it will move up and down, and when I press the Menu
button (showing my ap''s menu) it will "fix" the view...

Any idea what the problem is ? The app is running on a ADP2 with
Android 1.6 Thanks in advance !

Ok, after some testing I noticed that if I don't run the Activity on
Fullscreen, but just leave the TtileBar away this won't happen...
Still this is no solution to me, I want it to be fullscreen...

then the Backgrounddrawable still was there but the Progress
disapeared.
@Droidsan could you post an example please? I don't quite get what you

[android-developers] Re: ProgressBar.setProgressDrawable bug

[Dave Rowntree]

hi is02
I found the same problem :(
It only occurs setting the ProgressDrawable in code. If you set it in
xml it works ok.

A workaround is to define another (dummy) ProgressBar/SeekBar in your
xml layout (you can define it as invisible), and set that one's
ProgressDrawable in your xml to your drawable (e.g.
android:progressDrawable="my_progress_drawable").

You can then access and use the invisible progressbar's
progressDrawable in code (dummyProgressBar.getProgressDrawable), and
set it as the progressDrawable of any other progressbar/seekbar  (e.g.
myMainProgressBar.setProgressDrawable(myDummyProgressBar.getProgressDrawable).

If you need several alternative progressdrawables for your
progressbar, you can define a dummy invisible progressbar for each
alternative. (adds an overhead to screen layout of course but hey, it
is a workaround).

Putting dummy progressbar's progressdrawables into Drawable objects in
your activity is better than re-acquiring them every time from a dummy
progressbar. e.g.

Drawable progressDrawableDefault;
Drawable progressDrawable2;

progressDrawableDefault = myProgressBar.getProgressDrawable();
progressDrawable2 = dummyProgressBar2.getProgressDrawable();

You can then allocate any of your drawables to your main progressbar.
e.g.
myProgressBar.setProgressDrawable(progressDrawable2);

Do remember though, allocating the same drawable to multiple progress
bars is NOT good. e.g. changes to one ProgressBar.progress affects the
display of ALL progress bars progress sharing the same
progressdrawable resource(hence the need to use dummy progressbars).

Hope this helps.

[android-developers] Re: ProgressBar.setProgressDrawable bug

[droidsan]

When using the progress drawable provided by the Android platform it
should not be possible to change the color dynamically as you cannot
access the GradientDrawable. The resource ID for the GradientDrawable
used as progress indication is defined in com.android.internal.R and
you do not have access to it from your application. Changing colors
dynamically should be possible if you use your own drawable as
progress drawable.

The platform's (horizontal) progress drawable is a clipped
GradientDrawable inside a LayerDrawable (see
http://android.git.kernel.org/?p=platform/frameworks/base.git;a=blob_plain;f=core/res/res/drawable/progress_horizontal.xml;hb=HEAD).
You can use it in your application and replace the progress drawable
with it. However, to get access to the GradientDrawable from Java you
should package the GradientDrawable inside a ScaleDrawable (instead of
packaging it inside of a ClipDrawable). Then you can get access to it
via ScaleDrawable.getDrawable().

Kind regards

Droidsan

Re: [android-developers] java.lang.OutOfMemoryError: bitmap size exceeds VM budget

When you get such an error it's because *your* process is running out

too much memory in your process and blowing past the heap limit (16 MB
or 24 MB depending on the device you're using.)

[android-developers] Re: Playing live stream (RTP) in MediaPlayer

[Jez]

Thanks,

I'll give this a try on the 2.1 (Desire) and see if it'll work - as
I'm slightly suspiscious that
it may have problems with TRUE live video (aka from an encoder) but
will post here with what I find.


Hoping always

[android-developers] Re: Droid Incredible Not Returning Valid DeviceID?

[Maps.Huge.Info (Maps API Guru)]

Have you considered using Settings.Secure.ANDROID_ID instead? It seems
relatively stable and doesn't require additional permissions to use
it.

[android-developers] How to use AudioManager.OnAudioFocusChangeListener in FroYo?

[mort]

I'd like to respond in my music player to other apps (like Maps)
gaining an audio focus.
However, I only found requestAudioFocus to pass a listener. But I
don't want the focus (it's just fine to have music in background), I
just want to be notified if some other app requests it.
Did I miss(understand) something? Or isn't own handling necessary at
all and Android mutes/softens the volume itself? However, esp. for
audio books it might be a good idea to pause instead of just mute the
sound, so having a listener wound be nice anyway...

[android-developers] java.lang.OutOfMemoryError: bitmap size exceeds VM budget

[Amit]

Hi

java.lang.OutOfMemoryError: bitmap size exceeds VM budget
I am getting this message in my log. As I investigated and found out
while loading contact image this error comes.I checked  size of the
image file and it was normal so came to a conclusion that other
processes filling up the memory and hence at the time this image is
being loaded ,VM running low of memory.

My question is that, is there any tool to figure out which process is
responsible for occupying memory so that we can look into the process
for the exact reason.

Thanks,
Amit
