Answer 1

-If you have internet over proxy you will get grids . -Use the default debug keystore for generating API key and try .

Answer 2

Are you sure your API key is correct? When the API key doesn't match, it shows the grid instead of the map.

Running the app from Eclipse directly on the emulator / an actual phone requires a different key then when you build the .apk file first and run that on a device.
