问题
I have an application based on the MapActivity. The application drops ItemizedOverlay items on the map as you start to move about. It has been running with no problems until I dropped it into a Nexus 2.2 phone.
I'm running into a weird problem where sometimes when I zoom in/out too fast, or pan too fast, the MapView will go "white" and my Overlay items will get shoved into the upper left hand corner.
The only error I've seen in my log is:
E/PixelConverter( 4881): Setting singular matrix Matrix{[0.0, 0.0, 152.0][0.0, 0.0, 347.0][0.0, 0.0, 1.0]}
My Map keys are working fine. I have internet permissions setup on the phone too.
I'm scratching my head over this one.
