ANR keyDispatchingTimedOut - AIR for Android

ANR keyDispatchingTimedOut - AIR for Android - android

In an Adobe AIR application compiled for Android I am getting ANR errors with the cause keyDispatchingTimedOut. The workflow is as follows:
Sounds are playing, an embedded SWF is playing.
User presses a button - sounds/SWF stop playing
Application waits 3 seconds
Application makes some asynchronous calls to a server
Application handles the result, and pushes a new view to the viewstack.
New view appears
Between 5-10% of the time, after a few seconds, the ANR occurs.
Nothing in the error report really stands out. Any help would be massively appreciated. This is driving me crazy!
I have attached the ANR error report:

EGL14.eglMakeCurrent freezes my game

I followed this tutorial in order to capture a video of my game, and it's working. I tested on several devices, and it's working. But it fails with a Nexus 7 (2012). The game freezes.
Debugging the library, I found that the call to EGL14.eglMakeCurrent in line 143 of this file is causing it.
Why EGL14.eglMakeCurrent call may block the execution?
EDIT: There is nothing in logcat when game freezes. I can only get this information from adb bugreport:

Finally I found the problem. There is a bug in Tegra drivers that causes a deadlock when using shared contexts. More info:

Android ANR WaitingInMainSignalCatcherLoop

I'm having a very hard time debugging an Android ANR problem.
This is what I get in logcat:

Does anyone know what can usually cause these sorts of errors? I can't pinpoint it to any particular line of code but it does seem to happen on starting the app sometimes.
Thanks

query all contacts in ContentResolver resolved in ANR

I encountered in an annoying bug, that happens only on Nexus 4. Everytime, when I'm going through all the contacts of the device I'm getting ANR. Obviously, first thing that I did is to go through the traces.txt in order to find if there were deadlock or starvation and there weren't.
Here is how I'm using the ContentResolver:
Cursor c = cr.query(ContactsContract.Data.CONTENT_URI, PROJECTION_NAMES, WHERE_NAMES, new String[] { contact.getPhoneBookId() }, null);

Nasty ANR caused by MediaCodec.dequeInputBuffer

I have witnessed and have received reports of a rare but particularly nasty ANR in my app that causes the app to be completely useless unless it's uninstalled and reinstalled, not even Force Stopping the app (which is supposed to shutdown the entire process) can get the app out of the ANR.
I haven't been able to get anything out of the ANR reports, but this one has some useful information. It appears MediaCodec.dequeueInputBuffer is not returning. It is being given a timeout of 200000 microseconds. This is happening in a synchronized block of code off the main thread, in which all operations involving the MediaCodec and MediaExtractor objects take place. The main thread is waiting for the lock to enter a code block containing a call to MediaExtractor.seekTo().
The whole code for SoundTouchPlayable and MediaCodecAudioDecoder can bet found at https://github.com/svenoaks/SoundTouch-Android/tree/master/src/com/smp/soundtouchandroid
The lockup in the non-main thread is happening in MediaCodecAudioDecoder line 181.
I'm not really sure what, if anything, I can do about this. What can I do?

EDIT 1:
ANRs are triggered by either of the following conditions.
No response to an input event (such as key press or screen touch events) within 5 seconds.
A BroadcastReceiver hasn't finished executing within 10 seconds.
Since your timeout is set to a sub-second value, it's not likely to be the direct source of your problem. The problem is more likely to be a result of the synchronization blocks. If you have code running on the main thread that's being delayed due to thread synchronization, that could easily trigger one of the ANR conditions.
I'll take a look at your actual code a bit later tonight if nobody else has already determined the problem.
EDIT 2:
Looking at the ANR dump in the question and the code, the issue appears to be caused by lock-contention on decodeLock when trying to do a seek. The thread holding the lock is a native thread gotten to by the path SoundTouchPlayable.run()->SoundTouchPlayable.playFile()->MediaCodecAudioDecoder.decodeChunk()->MediaCodecAudioDecoder.advanceInput().
To arrive at that, I looked for "waiting" in the ANR dump. Those that are on Object.wait aren't a problem; they're just waiting for more messages. The only one that's different is waiting to lock <0x422cfb18> (a java.lang.Object) held by tid=20. Then it's just a matter of looking to see which threads has tid=20.
I suggest determining how/why those two different threads could be running at the same time. Then working out a plan to keep them from do so or if it's OK that they run at the same time, changing the synchronization locks to allow it.
To address the fact that you have to do an uninstall to recover, consider that a simple force-stop might be leaving some process running. An uninstall will be more aggressive about finding and killing all processes running under that user id (each app has its own).
