Firebase Authentication API Email/Password Android

I am attempting to write an app for android that uses Firebase Authentication via Email/Password. It is enabled. However the tutorial, and the code in Github for the examples are showing:

private FirebaseAuth mAuth;

dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
testCompile 'junit:junit:4.12'

compile 'com.android.support:appcompat-v7:23.4.0'
compile 'com.android.support:cardview-v7:23.4.0'
compile 'com.android.support:design:23.4.0'
compile 'com.google.firebase:firebase-core:9.0.2'



}


apply plugin: 'com.google.gms.google-services'

However, I get an error as if the "FirebaseAuth" doesn't exist. However the latest documentation says otherwise.

Github sample code

enter image description here

Any help would be greatly appreciated.

According to documentation in the firebase web page you should create a Firebase object using the URL from your firebase and from there create usernames with passwords or log them in. The code you showed used this FirebaseAuth for that.

Here is the code to create a new user:

Firebase ref = new Firebase("https://<YOUR-FIREBASE-APP>.firebaseio.com");
ref.createUser("[email protected]", "correcthorsebatterystaple", new Firebase.ValueResultHandler<Map<String, Object>>() {
    @Override
    public void onSuccess(Map<String, Object> result) {
        System.out.println("Successfully created user account with uid: " + result.get("uid"));
    }
    @Override
    public void onError(FirebaseError firebaseError) {
        // there was an error
    }
});

Here is the code to log him in:

Firebase ref = new Firebase("https://<YOUR-FIREBASE-APP>.firebaseio.com");
ref.authWithPassword("[email protected]", "correcthorsebatterystaple", new Firebase.AuthResultHandler() {
    @Override
    public void onAuthenticated(AuthData authData) {
        System.out.println("User ID: " + authData.getUid() + ", Provider: " + authData.getProvider());
    }
    @Override
    public void onAuthenticationError(FirebaseError firebaseError) {
        // there was an error
    }
});

Got all of this info from the quick start guide here: https://www.firebase.com/docs/android/guide/login/password.html#section-logging-in

Hope it helps.

Replace the com.google.firebase:firebase-core:9.0.2' dependency with the com.google.firebase:firebase-auth:9.0.2 dependency. So:

compile 'com.google.firebase:firebase-auth:9.0.2'

instead of

compile 'com.google.firebase:firebase-core:9.0.2' under your dependencies.

I did not find the FirebaseAuth class in the core dependency but I did find it in the auth dependency. Furthermore, if you checkout their dependencies list, they do not add the core dependency, they add the auth dependency instead.
