I'm trying to determine when Google Maps has finished downloading new tiles after a zoom change or panning. I’ve read the discussion about testing for the center coverage tile, but that doesn’t tell me if other map tiles are still being downloaded. I need to know when the last tile has been downloaded so I can call invalidate. The problem is that when ACTION_UP motion event is called from the “fake” Click Receiver overlay, I started downloading my PNG overlays at the same time the new Google Map tiles start downloading. If my overlays are downloaded first, as new Google Map tiles arrive, my overlays get removed or the whole map blinks. Since the Google Map tiles are larger than my overlays this occasionally happens, especially in a 1xRTT environment. If the Google Map tiles finish first then everything is fine. I’m using an XML layout to define my mapView. I’ve tried programmatically adding the mapView to a View without luck. There must be some way to deterministically know when to interact/overlay images on a Google Map background.
