title: Google Maps API 2 MapView Not Updating
body: <p>I'm displaying a Google Maps API v2 MapView in an Android app, but it's curiously not updating properly in a consistent fashion. I'm using the GPS to update the map position (tried both LocationManager and LocationClient) and although the map moves to the position, about fifty percent of the time either the street name layer fails to update or there's a fuzzy/blurry section that fails to update--until I do a manual drag (scroll) of the map.  Then the entire map updates instantly. I've stripped out a lot of the processing in the app to see if I was somehow preventing a refresh, but it didn't make a difference.</p>
  
  <p>I inserted a mapView.invalidate() call in onCameraChange but that oddly seemed to make the problem occur more readily (although still not 100% of the time).</p>
  
  <p>I am implementing all of the Activity callbacks as required by MapView.</p>
  
  <p>Has anyone encountered a problem like this with Google Map API v2 on Android? If so, did you identify the cause and how did you solve it?</p>
