title: Android Video View - can't play this video
body: <p>I have few tutorial screens in my app, and on some Samsung device, I get this error when trying to play it:</p>
  
  <pre><code>Can't play this video
  </code></pre>
  
  <p>The said video is in the app's package, and not on some external source like SD card, so I don't know whats the problem... The video is in <code>.mp4</code> format, here is how I play it</p>
  
  <pre><code>    vvTutorial = (VideoView) v.findViewById(R.id.vvTutorial);
      Uri myUri = Uri.parse("android.resource://" + getActivity().getPackageName() + "/" + R.raw.video_tut_4);
      vvTutorial.setMediaController(null);
      vvTutorial.setVideoURI(myUri);
      vvTutorial.start();
      vvTutorial.setOnPreparedListener(new OnPreparedListener() {
  
          @Override
          public void onPrepared(MediaPlayer mp) {
              mp.setLooping(true);
          }
      });
  </code></pre>
  
  <p>Whats wrong, why is it giving this error only on this device, but not on the others I've tested?</p>
