Is it possible to make different Firebase Database for Release and Debug mode in a single project/app?

Question

Here we are working on the project that uses the Firebase Realtime Database. Is it possible to make different Firebase Database for Release and Debug mode in single Android app?

Project:(App with release/debug mode)

1. Debug Mode(Test Environment) - Firebase Database 1
2. Release Mode(Production Environment) - Firebase Database 2

What is the best idea to solve this Test/Production environment for Firebase Database?

Answer 1

There is only a single database in a project at the moment. So either you'll need to model debug and release data into the same database or you'll need a separate project for each.

Many of these scenarios are covered in this blog post: Organizing your Firebase-enabled Android app builds.

Answer 2

Rather than using google-services.json to drive initialisation of Firebase (assuming that's what you're currently doing?), I'd suggest dynamically creating FirebaseApp using something like following

    String apiKey;
    String databaseUrl;

    if (useDebugDatabase) {
        apiKey = "xxxxxx";
        databaseUrl = "<debug firebase database url>";
    } else {
        apiKey = "xxxxxx"
        databaseUrl = "<release firebase database url>";
    }


    FirebaseOptions firebaseOptions = new FirebaseOptions.Builder()
            .setApiKey(apiKey)
            .setApplicationId(context.getString(R.string.google_app_id))
            .setDatabaseUrl(databaseUrl)
            .build();
    FirebaseApp firebaseApp = FirebaseApp.initializeApp(context, firebaseOptions, "MyApp");

    FirebaseDatabase database = FirebaseDatabase.getInstance(firebaseApp);
