Cannot create org.webrtc.voiceengine.WebRtcAudioManager on Android

I have a functional implementation of native (C++) WebRTC in Windows, which I'm trying to get working on every other platform now. Currently, I'm attacking Android.
When I call webrtc::CreatePeerConnectionFactory, it cannot create the java class org.webrtc.voiceengine.WebRtcAudioManager. I get the following result (followed by a crash!):

This what that failing Java line looks like:
audioManager =
(AudioManager) ContextUtils.getApplicationContext().getSystemService(Context.AUDIO_SERVICE);
I'm using WebRTC M103 (branch-heads/5060).
I've linked to libwebrtc.a, dynamically loaded libjingle_peerconnection_so.so, and bundled libwebrtc.jar. All of those seemed to be required dependencies, and advanced the ball for me one-by-one as I added them into the equation.

Fixed! This is what I was missing:
I was calling webrtc::JVM::Initialize prior to webrtc::CreatePeerConnectionFactory (which is one of many Droid specific requirements they don't bother mention in any docs...). But, I missed the fact there is an overload which takes the Droid app context (i.e. static void Initialize(JavaVM* jvm, jobject context);). That is to say, I was only passing the jvm pointer when initializing.
After a mini adventure (for which I'll omit the details) to get the context reference on C side, and not have it go "stale" (when the Java GC would delete it), I passed that along to the initialization. That, in turn, allowed that (original issue) of the Java invocation of ContextUtils.getApplicationContext() to work!

m3u8 file not playing in Android Emulator

I am trying to playback a m3u8 file in Android Emulator.
http://devimages.apple.com/iphone/samples/bipbop/bipbopall.m3u8
It's not able to playback the video but audio is heard.
I get the following error E/OMXNodeInstance( 39): OMX_GetExtensionIndex failed.
I traced the calls and I see that the video decoder is not instantiated properly,
I find that OMXNodeInstance::enableGraphicBuffers is getting called and that calls,
OMX_ERRORTYPE err = OMX_GetExtensionIndex(...,const_cast<OMX_STRING>("OMX.google.android.index.enableAndroidNativeBuffers"),...);
which is then calling OMX_ERRORTYPE SoftOMXComponent::getExtensionIndex,
but there is no implementation for this function.
It just returns UndefinedError (code below)
OMX_ERRORTYPE SoftOMXComponent::getExtensionIndex(const char *name, OMX_INDEXTYPE *index)
{
return OMX_ErrorUndefined;
}
Can somebody please help me to overcome this GetExtentionIndex failure.

Try to run it in real device, as I know emulators with some specific sdk's(like 3.1) crash playing m3u8 file. And if didn't resolve the issue maybe you can use some 3rd paty plugins like Vitamio http://vitamio.org/

This is a very interesting question. From your logs, I would like to quote this portion
E/OMXNodeInstance( 39): OMX_GetExtensionIndex failed
V/OMXNodeInstance( 39): enableGraphicBuffers at 301 OMX_GetExtensionIndex returned 2147487745
These 2 error messages are received during initNativeWindow call of the ACodec as part of it's transition from LOADED to IDLE state. From an OMX perspective, as part of the LOADED to IDLE transition, ACodec::LoadedState::onConfigureComponent is invoked. As part of this function, initNativeWindow is invoked.
In initNativeWindow, there are two distinct conditions. The first case is when the user has provided a nativeWindow or rather a Surface or SurfaceTexture to the codec to write it's output into. The other case is when the user hasn't provided a Surface to the MediaPlayer engine.
V/ACodec ( 39): onStart
V/ACodec ( 39): [OMX.google.h264.decoder] Now Loaded->Idle
From these logs, it can be observed that the return code of initNativeWindow is ok which is only possible if the control branched to the case where mNativeNativeWindow is NULL as observed here. The return code for the false case is not caught by the ACodec which means that the component transitioned to IDLE state successfully.
In a nutshell, the issue is mainly arising due to a Surface not being provided to the MediaPlayer.
Some Suggestions:
Since you are employing NuPlayer, I would recommend you to check if NuPlayer::setVideoSurfaceTexture is called and whether a non-NULL object is passed from NuPlayer to downstream components.
From a MediaPlayer perspective, you should set a surface as part of the setSurface call.
In general, you need to provide a sink for the video decoder chain.

E/OMXNodeInstance( 39): OMX_GetExtensionIndex failed
V/OMXNodeInstance( 39): enableGraphicBuffers at 301 OMX_GetExtensionIndex returned 2147487745
the call to OMX_GetExtensionIndex lands into SoftOMXComponent(here) which is just a stubbed function and always returns OMX_ErrorUndefined which leads to failing of enableGraphicBuffers

native_window_set_buffers_geometry failed

I am trying to develop a surveillance application in OMAP 4460(Blaze Tablet-in ICS) acting as client device rendering the surveillance feed from a remote source. To begin with, surveillance feed is streamed remotely from the camera and port forwarded as RTP packets which are received and rendered in OMAP 4460 through a customized RTP stack. While rendering, I am getting the following error from the decoder, saying that "Surface Texture has been abandoned and native_window _set_buffers_geometry failed", more frequently.
Following is the log captured:

My English is not good.
Check SurfaceTexture pointer.
If you define sp<.....> in function, sp<.....> is abandoned with end of function.

Can't play mp4 video in my Android app

I very want to play mp4 video in my android app. I even wrote a bit of code for it:
String sourceUrl = "http://tvstream.cn.ru/storage/1kanal/20120530/"
+ "1kanal-20120530-01-14-00-20120530-03-16-00.mp4";
final VideoView videoView = (VideoView) findViewById(R.id.videoView);
getWindow().setFormat(PixelFormat.TRANSLUCENT);
final MediaController mediaController = new MediaController(this);
mediaController.setMediaPlayer(videoView);
videoView.setMediaController(mediaController);
videoView.setVideoURI(Uri.parse(sourceUrl));
videoView.setOnPreparedListener(new OnPreparedListener() {
public void onPrepared(MediaPlayer mp) {
videoView.requestFocus();
videoView.start();
mediaController.show();
}
});
But nothing works :( When I launch my app in emulator (Android 2.3.3) I've got weird stacktrace with some common error codes:
After few hours off googling and experiments I decided to try to launch my app on real device and watch logcat:

As I know, Android supports playback of video decoded with h264 (http://developer.android.com/guide/appendix/media-formats.html). So, can anyone tell me what I do wrong.

Probably your file is using an unsupported profile, notice that official media formats page only lists Baseline Profile as supported for H.264 AVC.
Try transcoding the video specifying Baseline Profile as suggested in this stackoverflow question, i.e. if your container is MP4 run:
ffmpeg -i yourfile.mp4 -c:v libx264 -profile:v baseline -level 1 yourfile_BaselineProfile.mp4
If this works it's not a issue in your code, you just have to use supported formats.

Try this
File clip=new File(Environment.getExternalStorageDirectory(),
"test.mp4");
if (clip.exists()) {
video=(VideoView)findViewById(R.id.video);
video.setVideoPath(clip.getAbsolutePath());
ctlr=new MediaController(this);
ctlr.setMediaPlayer(video);
video.setMediaController(ctlr);
video.requestFocus();
video.start();

VideoView classes does not allow playing MP4 file format videos. Please go through this link for Android Media Formats. Try checking your video with Daroon Player

Bluetooth connection lost issue

This is not really something I'm developing, more like something I'm trying to debug. For some reason my HTC Desire HD keeps disconnecting from my car's bluetooth. It worked fine on phone's original rom, then I upgraded to Gingerbread (HTC rom) and it started to disconnect. I'm not sure what happened next (possibly I've installed something? mb the car's computer was reset as I had a service?) but it actually started to work after a few months and all was good until I upgraded again to 2.3.5 (HTC official upgrade). The phone connects to my car without any issues, then looses the connection within a minute and will not reconnect until the phone or the car's restarted. Here's some log data that I was able to collect in case someone might be familiar with how the bluetooth works on android:
