Audio focus on my app when tv is running in google tv

Question

I need my app to get the audio focus when tv is ruuing a channel and my app is launched and loose focus when it goes to background. I tried it but not working in google tv. I tried mAudioManager.requestAudioFocus(this,AudioManager.STREAM_MUSIC,AudioManager.AUDIOFOCUS_GAIN); It working in device.i.e music stopped as app launched. but not worked in google tv with any parameters. Steps for audio focus are:

1.In MainApp

 AudioManager  mAudioManager = (AudioManager) getSystemService(Context.AUDIO_SERVICE);
requestFocus();

In onresume()

protected void onResume() {
    super.onResume();
    requestFocus();
}

3.in onStop()

    protected void onStop(){
        abandonFocus();
        super.onStop();

        Log.e("APPLICATION", "APPLICATION onStop");
    }

4.in onDestroy()

public void onDestroy(){
    super.onDestroy();
    //Log.e("APPLICATION", "APPLICATION onDestroy");
    abandonFocus();
}

5.Methods for AudioFocus.

/** Requests audio focus. Returns whether request was successful or not. */
        public boolean requestFocus() {
         return  AudioManager.AUDIOFOCUS_REQUEST_GRANTED ==
                mAudioManager.requestAudioFocus(this, AudioManager.STREAM_DTMF, AudioManager.AUDIOFOCUS_GAIN);


        }



        /** Abandons audio focus. Returns whether request was successful or not. */
        public boolean abandonFocus() {
            return AudioManager.AUDIOFOCUS_REQUEST_GRANTED == mAudioManager.abandonAudioFocus(this);
        }



        /**
         * Called by AudioManager on audio focus changes. We implement this by calling our
         * MusicFocusable appropriately to relay the message.
         */
        public void onAudioFocusChange(int focusChange) {

            switch (focusChange) {
                case AudioManager.AUDIOFOCUS_GAIN:
                    Log.e("AUDIOFOCUS","AUDIOFOCUS_GAIN");
                    break;
                case AudioManager.AUDIOFOCUS_LOSS:Log.e("AUDIOFOCUS","AUDIOFOCUS_LOSS");
                case AudioManager.AUDIOFOCUS_LOSS_TRANSIENT:Log.e("AUDIOFOCUS","AUDIOFOCUS_LOSS_TRANSIENT");

                    break;
                case AudioManager.AUDIOFOCUS_LOSS_TRANSIENT_CAN_DUCK:Log.e("AUDIOFOCUS","AUDIOFOCUS_LOSS_TRANSIENT_CAN_DUCK");
                    break;
                 default:
            }
        }

I tried it out here and gaining/receiving audio focus works on Google TV. The issue might be that the app that was running before your app is not releasing audio focus.

Audio focus does work on Google TV but not all applications respect audio focus. I wrote a blog post about how to utilize Audio Focus properly (http://android-developers.blogspot.com/2013/08/respecting-audio-focus.html) but there is no solution for applications that ignore it or do not use audio focus.
