                    pDialog.dismiss();

                    System.out.println("Video Play Error :" + e.toString());
                    finish();
                }

Answer 1

The media player work is done asynchronously from your code. If the media failed to setup, then the fail will occur after the code finished your method. At the same time, onPreparedListener wasn't called since the media did't enter in a PREPARED state. So try to add an OnErrorListener:

videoview.setOnErrorListener(new MediaPlayer.OnErrorListener(){
    public boolean onError(MediaPlayer mp, int what, int extra) {
        // inform the user something went wrong
        mProgressDialog.dismiss();
        return true;
    }
});

If this doesn't work check what callback you're getting for your media player / videoview.
