title: OnAudioFocusChangeListener does not get executed when native player is paused
body: <p>I have this strange issue when if I play song with custom app player, it works fine when I receive calls OnAudioFocusChangeListener gets called which in turn deos all the appropriate things to lower the players volume. However when  have started a native android player and paused it and than started our app player it see not to do the same but just send a call notification only, no audio focus event. What could possibly cause it?</p>
  
  <p>Here are the steps:</p>
  
  <ul>
  <li>Start android native player</li>
  <li>pause it</li>
  <li>start our app player</li>
  <li>call this handset</li>
  <li>music does not pause within our player because we don't receive OnAudioFocusChangeListener but only CallStateListener gets called. </li>
  </ul>
  
  <p>Is it possible that OS does not send lower volume notification b/c Native OS player is paused?</p>
  
  <p>Thank you</p>
