How to configure dynamic app_id programmatically for Google Play game services?

Question

In my project I need to configure app_id at runtime, but for now I have found only one way, with Manifest.

<meta-data android:name="com.google.android.gms.games.APP_ID" android:value="@string/app_id"/>

Can I do it progammatically? Maybe in nearest releases?

If you are using Android Studio for you application programming than you can achieve it by declaring you app_id string resource in app Gradle file.

Declare it in:

android {
    defaultConfig {
            applicationId "<YOUR PACKAGE>"
            .....
            resValue "string" "app_id" getApplicationId()
    }
}

and now you'll easily find the string resource R.string.app_id, which is automatically generated for you.
