Steps:

Setup the Firebase Auth REST SDK

1. Add the JitPack repository to your root build file

allprojects {
  repositories {
    ...
    maven { url 'https://jitpack.io' }
  }
}

2. Add the dependency in your app module build file

dependencies {
  implementation "com.github.anotherdev:firebase-auth-rest:x.y.z"
}

Where x.y.z = latest Firebase Auth REST SDK on

Example project: firebase-auth-rest

Steps:

1. Replace com.google.firebase.auth.FirebaseAuth with com.anotherdev.firebase.auth.common.FirebaseAuth.

FirebaseApp app = FirebaseApp.getInstance();
com.anotherdev.firebase.auth.common.FirebaseAuth auth = FirebaseAuthRest.getInstance(app);

2. Sign in anonymously function:

auth.signInAnonymously().subscribe();

3. Facebook Login function:

com.facebook.login.LoginResult fb;
String token = fb.getAccessToken().getToken();
// https://console.firebase.google.com/u/0/project/<your-app>/authentication/providers -> click on Facebook
String oAuthRedirectUri = "https://<your-app>.firebaseapp.com/__/auth/handler";
AuthCredential credential = com.anotherdev.firebase.auth.provider.FacebookAuthProvider.getCredential(token, oAuthRedirectUri);
auth.signInWithCredential(credential).subscribe();

4. Google Sign-In function:

GoogleSignInClient google;
startActivityForResult(google.getSignInIntent(), REQ_GOOGLE_SIGN_IN);

@Override
protected void onActivityResult(int requestCode, int resultCode, @Nullable Intent data) {
    super.onActivityResult(requestCode, resultCode, data);
    GoogleSignInAccount acc = GoogleSignIn.getSignedInAccountFromIntent(data).getResult();
    AuthCredential credential = com.anotherdev.firebase.auth.provider.GoogleAuthProvider.getCredential(acc.getIdToken());
    auth.signInWithCredential(credential).subscribe();
}

5. Listen to user login/logout:

auth.authStateChanges()
    .doOnNext(auth -> Log.i("FAR", "user auth state changed!"))
    .subscribe();

6. Logout function:

auth.signOut();
