Adding items to Android Maps Overlay does not immediately show on map. How do I fix?

Question

Hello,

I can't figure out how to tell my Map to redraw its overlays once I've updated them. Can someone enlighten me?

Currently the user has to touch the screen before the map is redrawn.

Thanks!

Answer 1

Try calling populate() on the overlay that contains the pins.

Answer 2

I think you must call invalidate() from an UI thread or postInvalidate() from an non-UI thread on the MapView object you are using.
