Hi Christoph, thanks for your suggestion, but from playing with your library demonstrator you seem to be have the same problem I identified with my solution: since the only event available from the framework is when the user lifts his finger from the touchscreen (MotionEvent.ACTION_UP), the area used for retrieving the markers may be different than the area which is shown after the scrolling animation stops.
To test this I compiled your demonstrator with the createOverlayWithLazyLoading() method, zoomed in a bit and made quick horizontal swipes. When I did this, no markers would show up because the decelaration animation would move beyond the area calculated at the moment I lifted my finger (or, in the emulator, my mouse). I couldn't confirm that this was really the case because I couldn't find the source code for the library anywhere, even though your project is listed as being GPL2. So I'm back to square one: I need to know how to get an event when the map deceleration animation finishes. Right now, I don't think that this is available from the framework. If that's the case, then I'll open a bug report with the official repository.
