title: Pause/resume mediaPlayer on notification sound
body: <p>It's easy to detect when phone calls come in (via phoneStateListener), but what about other notification sounds, such as email or sms?  </p>
  
  <p>On some devices, these notification sounds mute but don't pause any currently running mediaPlayer instances, which is annoying for the user.  Ideally, I'd like to listen for notifications that play sound, pause playback for the duration, and then resume playback afterwards.</p>
