            getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
                    WindowManager.LayoutParams.FLAG_FULLSCREEN);
        }
    }
}

this is my code. two thing i want to add here one is rotation option and second is after rotation start video from the same position from here it runs. Basically i want to run a video using a url. but like youtube there is no rotation icon. It has only three icon in the VideoView app. One is pause/play one is forward and one is backword.
