title: VideoView triggers OnPreparedListener too early for HLS
body: <p>I want to show user some ProgressDialog while he waits for VideoView to start play HLS. I try to use OnPreparedListener for this, but he triggers to early (after player downloaded m3u8 file, not when video started).</p>
  
  <pre><code>VideoView player = (VideoView) findViewById(R.id.player);
  String httpLiveUrl = "http://example.com/playlist.m3u8";
  
  player.setVideoURI(Uri.parse(httpLiveUrl));
  player.setMediaController(new MediaController(this));
  player.requestFocus();
  
  player.setOnPreparedListener(new OnPreparedListener() {
  public void onPrepared(MediaPlayer mp) {
      progress.dismiss();
  }
  });
  
  progress.show();
  player.start();
  </code></pre>
  
  <p>I didn't find another suitable listner... May be anyone knows sloution?</p>
