    TODO: Before you release your application, you need a Google Maps API key. 

    To do this, you can either add your release key credentials to your existing 
    key, or create a new key. 

    Note that this file specifies the API key for the release build target. 
    If you have previously set up a key for the debug target with the debug signing certificate, 
    you will also need to set up a key for your release certificate. 

    Follow the directions here: 

    https://developers.google.com/maps/documentation/android/signup 

    Once you have your key (it starts with "AIza"), replace the "google_maps_key" 
    string in this file.
