    public void onConfigurationChanged(Configuration newConfig) {

    super.onConfigurationChanged(newConfig);
          if(newConfig.orientation == Configuration.ORIENTATION_LANDSCAPE){
           this.getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
           WindowManager.LayoutParams.FLAG_FULLSCREEN);       surfaceView.setLayoutParams(lp11);
          } else {       final WindowManager.LayoutParams attrs = getWindow().getAttributes();
      attrs.flags &= (~WindowManager.LayoutParams.FLAG_FULLSCREEN);
      getWindow().setAttributes(attrs);      }
    }
