How to define android:label for different productFlavors in build.gradle

Question

Is there a way to specify different app label (name) for different productFlavors in build.gradle? For example something like this:

productFlavors {
    stage {
        app name with "-stage" suffix
    }
    preprod {
        app name with "-preprod" suffix
    }
    prod {
        app name without any  suffix
    }
}

A friend of mine suggested a very nice solution based on injecting build variables into the manifest. It even allows to use localized app labels. So here it is:

1) Specify android:label in AndroidManifest.xml as follows:

android:label="${appLabel}"

2) Specify a default value in app level build.gradle:

manifestPlaceholders = [appLabel:"@string/appName"]

3) Override the value for needed product flavours:

productFlavors {
    stage {
        manifestPlaceholders = [appLabel:"@string/appNameStage"]
    }
    preprod {
        manifestPlaceholders = [appLabel:"@string/appNamePreprod"]
    }
    prod {
        // Just let it use a default value
    }
}

4) Add string resources which you are referring to (appName, appNameStage, appNamePreprod). Localize them if needed.
