Google Map doesn't appear on Android device

I am able to display my Google Map properly in my MapView when I sign my application with my debug keystore. When I try and sign it with a release ke开发者_Go百科ystore, the map appears but as blank tiles, no map tiles.

How can I get my release build to show the maps?

Double check your API keys.. if all looks fine and its still not working sign the app with a new key and corresponding new API key :-).

Your maps API key is matched with the keystore used to sign you app. Before signing your app with your release keystore, go over to http://code.google.com/android/maps-api-signup.html and generate a new API key.
