I am getting the following exception:
12-24 00:29:25.922: ERROR/AndroidRuntime(267): Uncaught handler:

com.google.android.maps.MapView.onDraw(MapView.java:454)
I believe this is whats happening:
I have a MapView with a few Map Overlays (simple markers),
occasionally the locations of the markers change so I clear the map
overlays using: "map.getOverlays().clear()" and insert new marker
overlays onto the map.
However, if I happen to be moving the map, or zooming the map when the
update occurs I get the above ConcurrentModificationException.
I tried synchronizing on the map overlay list, like:
synchronized (map.getOverlays()) {
// clear and update overlays
}
However I still get the above exception.
Can someone explain the correct way to clear overlays on a map and to
repopulate them without encountering ConcurrentModification
Exceptions.
Oh and I am calling: "map.postInvalidate()" to "refresh" the map and
display the changes made to the overlays. Is this the correct way to
"repaint" a map?
Thanks
