If you want to have your application full-screen, to have removed even the window title & everything else, you have to add the following to your activity creation code: protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); // make window full screen requestWindowFeature(Window.FEATURE_NO_TITLE); getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN); .. do your usual initialization stuff }
