Multiple google-services.json Per Product Flavour

I think this is a variation on other questions that have been posed on this subject.

I have two product flavors. I deploy my app in different environments, each of which talk to different Firebase projects. As such, for each flavor I need to be able to target a specific environment (dev, test, production, etc.)

Is there a way, I can make build variants of a flavor that select the appropriate google-services.json file without introducing new product flavors? Maybe I am approaching this problem in the wrong way...

Solution

  • The only way I was able to do this was to bypass use of google-services.json and create FirebaseApp instance dynamically e.g.

        if (<is dev>) {
        apiKey = <dev api key>;
        databaseUrl = <dev database url>;
    } else if (<is test> {
        apiKey = <>;
        databaseUrl = <>;
    } else // production {
        apiKey = <>;
        databaseUrl = <>;
    }


    FirebaseOptions firebaseOptions = new FirebaseOptions.Builder()
            .setApiKey(apiKey)
            .setApplicationId(context.getString(R.string.google_app_id))
            .setDatabaseUrl(databaseUrl)
            .build();

    return FirebaseApp.initializeApp(context, firebaseOptions, "MyApp");
