Android Audio Focus notes

Every app that plays audio must get the audio session before playing the audio 

for this the code is as below 

private void requestAudioFocusAndStartPlayer(boolean isResume)

{

    abandonAudioFocus();

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

    if(mAudioManager  != null)

    {

        int result = mAudioManager.requestAudioFocus(this,AudioManager.STREAM_MUSIC, AudioManager.AUDIOFOCUS_GAIN);

        if(result != AudioManager.AUDIOFOCUS_REQUEST_GRANTED)

        {

            Log.i(TAG,"Audio Focus request not granted result:"+result);

            stopPlayer();

        }

        else

        {

            if(isResume) {

                resumePlayer();

            }

            else

            {

                startPlayer();

            }

        }

    }

}
