Android Firebase Realtime DataBase Quick setup


Example

  1. Complete the Installation and setup part to connect your app to Firebase.
    This will create the project in Firebase.

  2. Add the dependency for Firebase Realtime Database to your module-level build.gradle file:

compile 'com.google.firebase:firebase-database:10.2.1'
  1. Configure Firebase Database Rules

Now you are ready to work with the Realtime Database in Android.

For example you write a Hello World message to the database under the message key.

// Write a message to the database
FirebaseDatabase database = FirebaseDatabase.getInstance();
DatabaseReference myRef = database.getReference("message");

myRef.setValue("Hello, World!");
