because the videoview does not show me anything

This is the code but it does not show me anything but the app closes

VideoView video;

@Override
protected void onCreate(Bundle savedInstanceState)
{
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    video = (VideoView)findViewById(R.id.pantallaVideo);
    video.setMediaController(new MediaController(this));
    video.setVideoPath("http://192.168.15.214/PruebaConexion/S01E01.mkv");
    video.start();
}

The error you give me is the following

  

MediaPlayer: setDataSource: IOException!   uri = link

and this other error

  

dalvikvm: Could not find class 'android.os.PersistableBundle',   referenced from method   com.example.erick.reproducingvideo.MainActivity.access $ super

PS: I have the server in my computer and the video is in mkv format
