Answer 1

Check out OnPreparedListener . Call start() from inside that event, since then the file will be ready to be played.

Answer 2

You haven't called videoPlay() method from any of the method, Call videoPlay() method from onCreate() after findViewById() of video view.

and remove View v from videoPlay() method,i think it's useless.
