Manage Google Maps API Key with Gradle in Android Studio

I know Gradle is powerful and I would like to manage the API keys for development/produciton of Google Maps

Currently I always need to manually comment one line and uncomment the other to make it work. Is there a way to do it automatically in Gradle with some custom release configuration ?

<!-- MapView v2 API -->
<uses-library android:name="com.google.android.maps" />
<meta-data android:name="com.google.android.maps.v2.API_KEY" android:value="[MY_DEV_KEY]" />
<!-- PROD
<meta-data android:name="com.google.android.maps.v2.API_KEY" android:value="[MY_PROD_KEY]" />
-->

Answer

Since you are using gradle you can do the following:

build.gradle

android {
  .. .. ...
    buildTypes {
       debug {
          resValue "string", "google_maps_api_key", "[YOUR DEV KEY]"
       }
       release {
           resValue "string", "google_maps_api_key", "[YOUR PROD KEY]"
       }
    }
  }

And in your AndroidManifest.xml

<meta-data
            android:name="com.google.android.maps.v2.API_KEY"
            android:value="@string/google_maps_api_key"/>

This way you only have one AndroidManifest.xml and you set value based on your build type. Hope this helps.
