Exoplayer shows Runtimeexception in android

After lots of research i found VideoView is not able to play all video formats due to codec,frame size,etc. So i found alternative of using Exoplayer Library in my project. Is it possible that i can run all type of videos using exoplayer. By implementing small part i am getting following error. I have already added exoplayer library. i have not added anythigng to UI.

Try using the single parameter constructor of the MediaCodecAudioTrackRenderer.

TrackRenderer audiorenderer = new MediaCodecAudioTrackRenderer(samplesource)

Also, you're forgetting to pass the surface to the video renderer. Look at step 4 of the main steps that the developer guide of Android gives you.

// 1. Instantiate the player.
player = ExoPlayer.Factory.newInstance(RENDERER_COUNT);

// 2. Construct renderers.
MediaCodecVideoTrackRenderer videoRenderer = …
MediaCodecAudioTrackRenderer audioRenderer = ...

// 3. Inject the renderers through prepare.
player.prepare(videoRenderer, audioRenderer);

// 4. Pass the surface to the video renderer.
player.sendMessage(videoRenderer, MediaCodecVideoTrackRenderer.MSG_SET_SURFACE,
        surface);

// 5. Start playback.
player.setPlayWhenReady(true);

(Source: http://developer.android.com/guide/topics/media/exoplayer.html)

I would also recommend to instantiate the player in the onResume() or the surfaceCreated(). The onCreate() is used for the setup of the global state of an Activity. (Source: http://developer.android.com/reference/android/app/Activity.html#ActivityLifecycle)
