body: <p>I am trying to play video song in my app with video-view. But I get nothing except a black screen, and display error 'can't play video'.It seems there are no errors as such in the code except log cat errors which I have never heard of.</p>
  
  <pre><code>VideoView videoView =(VideoView)findViewById(R.id.video_view_ex);
  
      MediaController mediaController= new MediaController(this);
      mediaController.setAnchorView(videoView);
  
      Uri uri= Uri.parse(Environment.getExternalStorageDirectory().getPath()+"/Memory Card/Video/Na Na Na Na -DJ 9dip.mp4");
      videoView.setMediaController(mediaController);
      videoView.setVideoURI(uri);
      videoView.requestFocus();
      videoView.start();
  </code></pre>
