Hey Igor, I am trying to subclass the Overlay class so that I can pull tiles (generated from MapTiler) from a website and put them on top of Google Maps that are showing. I am tryng to do this in Android. Could you provide some sample code that might help? Any and all help is appreciated. Thanks, Todd
