Answer 1

There was problem with the above code which i solved by introducing

   GestureOverlayView gestures = (GestureOverlayView) findViewById(R.id.gestures);
        gestures.setGestureStrokeAngleThreshold( 90.0f);

As the default value of the angle threashold is 40.0f because of which simple vertical gestures would be skipped so changed it to 90.0f, so finally setting the GestureStrokeAngleThreshold to a value closer to 90.0f works fine
