Hello, I'm running into the exact same issue you are, I need a way to figure out when the user finishes moving the map around so I can fetch fresh data from a XML source. This is really easy to do using the Maps API for Javascript, but the Android Maps API doesn't have anything like it.
I've been researching for a few hours and this solution you posted here is the only one I've found to this problem, this sounds like a bit of a hack though since you'd probably have to use an additional Overlay that can handle the event on the MapView, it sucks that there isn't something more elegant. The alternative I found is to use a WebView that can handle the Javascript version instead of a MapActivity... which may work for my purposes, but no clue if it's what you're looking for.
