 private boolean reqAudioFocus() {
        boolean gotFocus = false;
        int audioFocus = am.requestAudioFocus(this, AudioManager.STREAM_MUSIC,
                AudioManager.AUDIOFOCUS_GAIN);
        if (audioFocus == AudioManager.AUDIOFOCUS_REQUEST_GRANTED) {
            gotFocus = true;
        } else {
            gotFocus = false;
        }
        return gotFocus;
    }

 if (reqAudioFocus()) {

            mPlayer.prepareAsync();
        }

public void onAudioFocusChange(int focusChange) {

        if (focusChange == AudioManager.AUDIOFOCUS_LOSS) {
            am.abandonAudioFocus(this);
            mPlayer.stop();


        }

    }

"am" - AudioManager.

AudioManager.OnAudioFocusChangeListener
