In my actual project I need to draw a MapView with a given running/walking/cycling path on top of it.
I don't need the current position so I added an overlay just for the path (no MyLocationOverlay). The path is painted but I don't see the Map in the emulator - only the grey tiles. The apiKey is set in the layout (MapView) and INTERNET permission is set in the Manifest.
So I'm wondering if I need more. Is it the emulator simply not working well (I do have 3G and 2 bars in the emulator) or do I need something else? Do I need to build an additional overlay or add additional permissions (xxxLOCATION) to the Manifest.
Many thanks in advance hjw
