I cannot figure out the origin of the ConcurrentModificationException
. In my activity
I'm calling
updateMapOverlay()
. I'm also calling updateMapOverlay()
inside another Thread (a TimerTask
) that is invoked on regular intervals. I'm taking the appropriate locks when invoking updateMapOverlay()
from both the threads. Is this problem being caused because I'm invoking updateMapOverlay
from inside a non-UI thread (i.e., TimerTask
). Has anyone else faced a similar issue ?
private void updateMapOverlay() {
this.itemizedOverlay.refreshItems(createOverlayItemsList());
List<Overlay> overlays = mapView.getOverlays();
overlays.clear();
overlays.add(cotItemizedOverlay);
this.mapview.invalidate();
}
Thanks.
