WindowManager wm1 = (WindowManager)SmallPlay.this.getSystemService(Context.WINDOW_SERVICE);

wm = (WindowManager)getApplicationContext().getSystemService("window");

videoview vv==new videoview(getApplicationContext);
  wmParams = newWindowManager.LayoutParams();

  wmParams.format = 1;
  
  wmParams.flags = 40;
  wmParams.width = 300;
  wmParams.height = 200;
