Thought I'd write this up quickly, since I ran into it not too long ago, and then I saw someone asking about it recently online... If you're implementing some gesture recognition in your Android app, one of the first things you'll notice after you get it basically working, is that there's an annoying and mysterious delay between the time that you finish drawing the gesture, and the time that the processing of that gesture begins (i.e. when GestureOverLayView.onGesturePerformed gets called).

This is caused by the so-called "fade offset". If you're showing the gesture on the screen, then during this time period, the drawn gesture fades away. However, if you're not showing it, it's just a waste of time.

To eliminate this lag (the default duration of which is 400 milliseconds), call the following methods on your GestureOverlayView:

setFadeEnabled(false) setFadeOffset(0)

or use the equivalent android:fadeOffset and android:fadeEnabled properties in your view's layout XML.
