title: Android knowing if music is playing in specific instance of MediaPlayer
body: <p>I'd like to know if my Specific MediaPlayer instance is playing sound/music.
  MediaPlayer has the <em>isPlaying</em> method but it returns true even if the player is buffering and not playing.</p>
  
  <p>Any idea how to know if MediaPlayer <strong>really</strong> plays sound?</p>
  
  <p>Thanks.</p>
