I have created a MyLocationOverlay to display the current GPS location on a MapView

it looks something like



When I start my app it works fine and I can see the blue dot of my location. However if I leave the app running for a period of time the the blue dot eventually disappears.

Does anyone know why this is happening?

*edit* The only way I can get the dot to re-appear is to send new GPS coordinates in.

I have the same issue (can't see blue dot). Please, write the best practices here, if you will find a way to resolve this problem.
Thanks.

did you write the draw fucntion of the overlay...?

Yep. No problem with my own Draw function. But I want to show the big native attracted blue dot.

The same code shows blue dot on G1 device and doesn't show in emulator...

m_myLocationOverlay = new MyLocationOverlay(this, mapView);
mapView.getOverlays().add(m_myLocationOverlay);
m_myLocationOverlay.enableMyLocation();
m_myLocationOverlay.enableCompass();
