Launch ACTION_VIEW Intent to play mp4

Work on the exercise "Display Video thumbnail in ListView", override the method onListItemClick() to Launch ACTION_VIEW Intent to play the mp4 of the clicked item.

We can use the code below to play the Uri of "video/mp4" by launching ACTION_VIEW Intent.

Intent intent = new Intent();
intent.setAction(Intent.ACTION_VIEW);
intent.setDataAndType(intentUri, "video/mp4");
startActivity(intent);

 @Override
 protected void onListItemClick(ListView l, View v,
   int position, long id) {
  // TODO Auto-generated method stub
  //super.onListItemClick(l, v, position, id);
  
  String uriString = l.getItemAtPosition(position).toString();
  Uri intentUri = Uri.parse(uriString);
    
     Intent intent = new Intent();
     intent.setAction(Intent.ACTION_VIEW);
     intent.setDataAndType(intentUri, "video/mp4");
     startActivity(intent);
  
 }
