Your 'playVideoByMediaPlayer' method doesn't show the video because it has no visible surface to display it on: "new SurfaceView()" does not cause a Surface to be shown on screen, just like "new Button()" would not cause a button to appear on the screen. You have to make the view part of your layout. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Android Developers" group.
