Also, another issue I'm having, I can detect which points should be drawn in the view, but when I go to draw those points I call a method from the draw() method and I get a concurrent operation error:
02-11 03:47:11.848: ERROR/AndroidRuntime(2213): java.util.ConcurrentModificationException 02-11 03:47:11.848: ERROR/AndroidRuntime(2213): at java.util.AbstractList$SimpleListIterator.next(AbstractList.java:66) 02-11 03:47:11.848: ERROR/AndroidRuntime(2213): at com.google.android.maps.OverlayBundle.draw(OverlayBundle.java:41) 02-11 03:47:11.848: ERROR/AndroidRuntime(2213): at com.google.android.maps.MapView.onDraw(MapView.java:476) It only does this when I call the method from the draw() method, but if I don't do that then I can't get the correct longitude and latitude coordinates, because they wont update unless they're called from draw(), if that makes sense.
