Answer 1

Try the following:

 Uri video = Uri.parse(url); MediaController mediaController = new MediaController(this); mediaController.setAnchorView(VideoViewplayer); VideoViewplayer.requestFocus(); VideoViewplayer.setMediaController(mediaController); VideoViewplayer.setVideoURI(video); VideoViewplayer.setOnPreparedListener(new OnPreparedListener() { @Override public void onPrepared(MediaPlayer arg0) { VideoViewplayer.start(); } });
