Instead of relying on google-services.json and associated gradle plugin you can dynamically create FirebaseApp using something like following (I have this in dagger module)

    FirebaseOptions firebaseOptions = new FirebaseOptions.Builder()
            .setApiKey(apiKey)
            .setApplicationId(someApplicationId)
            .setDatabaseUrl(databaseUrl)
            .setStorageBucket(storageBucket)
            .build();

    firebaseApp = FirebaseApp.initializeApp(context, firebaseOptions, "MyApp");
