How to use two Firebase database in Android Studio?

To use two Firebase databases in Android Studio, you need to perform the following steps:

2. Add the Firebase SDK to your Android Studio project by downloading the google-services.json file for each Firebase project and adding it to your app directory.
3. Initialize Firebase in your app by calling the FirebaseApp.initializeApp(Context) method in your Application class or the main activity.
4. Create two separate instances of the FirebaseDatabase class, one for each Firebase project, by calling the FirebaseDatabase.getInstance() method and passing the relevant Firebase options.
5. Use the Firebase references to access and modify the data in the corresponding Firebase databases.

For example, to access the data from the default Firebase database, you can use the following code:

FirebaseDatabase database = FirebaseDatabase.getInstance();
DatabaseReference myRef = database.getReference("path/to/data");

To access the data from the second Firebase database, you need to create a separate instance of the FirebaseDatabase class and use the corresponding reference:

FirebaseOptions options = new FirebaseOptions.Builder()

FirebaseApp.initializeApp(context, options, "second_database");

FirebaseDatabase secondDatabase = FirebaseDatabase.getInstance(FirebaseApp.getInstance("second_database"));
DatabaseReference mySecondRef = secondDatabase.getReference("path/to/data");

In this way, you can use two Firebase databases in your Android Studio app and easily manage and store your app data.
