title: Callback on VideoView progress
body: <p>I'm looking for a way to get a callback when a <code>VideoView</code> is playing, indicating the video progress. Something like described <a href="http://code.google.com/p/android/issues/detail?id=145" rel="nofollow">here</a>, but for a <code>VideoView</code>. Polling the current progress every fixed duration seems a bad solution…</p>
  
  <p>Is there any listener existing for this that I missed?</p>
