Answer 1

You should use Product Flavors.

For example:

android {
    ...


    defaultConfig {
        minSdkVersion 8
        versionCode 10
    }


    productFlavors {
        dev {
            resValue "string", "google_maps_api_key", "DEV_API_KEY"
         }

        prod {
            resValue "string", "google_maps_api_key", "PROD_API_KEY"
         }
    }
}

You cannot both have the widget in your layout and set the API key in Java.

If you dynamically create the MapView via its constructor, you can supply the API key that way from Java code, but then you will need to dynamically add it to your layout.

That being said, I'd deal with the problem via your build process (e.g., based on debug/production build, copy the right XML file into the right directory).

You have to create google maps object dynamically. Your layout will contaion only parent layout for creating object.

Answer 4

This works for me.

This variant of MapView constructor is documented here: https://developers.google.com/maps/documentation/android/reference/com/google/android/maps/MapView

@Override
protected void onCreate(Bundle arg0) {
    super.onCreate(arg0);
    String mapApiKey = <your choice logic here>
    mMapView = new MapView(this, mapApiKey);
    setContentView(mMapView);
