I'm pretty sure you need a different maps API key when you release an android application.

I quote:

Keep in mind that each Maps API Key is uniquely associated with a specific signing certificate. That means that:

•When you are getting started on developing, you can register using the debug certificate created by the SDK tools.

•When you are ready to publish your application, you need to register again using the certificate with which you will sign your application for release. You must then update your MapView elements so that they reference the release API Key, rather than the debug Key, and then sign your application with your release certificate.
