title: What is difference between media.session.MediaController and android.widget.MediaController?
body: <p>I am using "android.widget.MediaController" for VideoView. Not sure when to use "android.media.session.MediaController" and what the difference is between them. Any idea? </p>

  videoView.setMediaController(mediaController);
  videoView.start();
  </code></pre>
