Google Maps v2 is not showing in the signed APK - Solution

You maybe tried the Google Map v2 sample from GitHub with an debug key and everything looks fine. But after exporting the App as a signed APK, the map is not showing anymore.
The reason is, that Google need different certificates, one for the app that uses the debug key and one for the app that uses the release key.
Make a new SHA-1 certificate with keytool and your release key and add a new line to your API Key in the API Console.

And if you like to use the Google Map v2 Android API for other Apps with different package names, this is possible too. Add a new line for every package name together with the SHA1-certificate.
