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:

    string in this file.
    <string name="google_maps_key" templateMergeStrategy="preserve" translatable="false">
