Answer 3

Yes, it is possible for multiple applications to access the same Firebase Database. From Android Studio v2.2 onwards, you can directly link an app to a Firebase database via the Firebase Assistant. Here is how to do so:

• Go to Tools and click on the Firebase option.

• From the Firebase Assistant, select Realtime Database

• Click on the Connect to Firebase button in the Assistant, which will show you a dialog allowing you to select an existing Database or create a new database. Click on Choose an existing Firebase project, select the Database you want to use and click on the Connect to Firebase button in the dialog.

• Your app will automatically get connected and you will be able to access your database.
