FirebaseUI for Android — UI Bindings for Firebase

FirebaseUI is an open-source library for Android that allows you to quickly connect common UI elements to Firebase APIs like the Realtime Database or Firebase Authentication.

A compatible FirebaseUI client is also available for iOS.

Installation

FirebaseUI is published as a collection of libraries separated by the Firebase API they target. Each FirebaseUI library has a transitive dependency on the appropriate Firebase SDK so there is no need to include those separately in your app.

In your app/build.gradle file add a dependency on one of the FirebaseUI libraries.

dependencies {
    // FirebaseUI Database only
    compile 'com.firebaseui:firebase-ui-database:1.0.1'

    // FirebaseUI Auth only
    compile 'com.firebaseui:firebase-ui-auth:1.0.1'

    // FirebaseUI Storage only
    compile 'com.firebaseui:firebase-ui-storage:1.0.1'

    // Single target that includes all FirebaseUI libraries above
    compile 'com.firebaseui:firebase-ui:1.0.1'
}

After the project is synchronized, we're ready to start using Firebase functionality in our app.

Compatibility with Firebase / Google Play Services Libraries

FirebaseUI libraries have the following transitive dependencies on the Firebase SDK:

firebase-ui-auth
|--- com.google.firebase:firebase-auth
|--- com.google.android.gms:play-services-auth

firebase-ui-database
|--- com.google.firebase:firebase-database

firebase-ui-storage
|--- com.google.firebase:firebase-storage

Each version of FirebaseUI has dependency on a fixed version of these libraries, defined as the variable firebase_version in common/constants.gradle. If you are using any dependencies in your app of the form compile 'com.google.firebase:firebase-*:x.y.z' or compile 'com.google.android.gms:play-services-*:x.y.z' you need to make sure that you use the same version that your chosen version of FirebaseUI requires.

For convenience, here are some examples:

FirebaseUI Version	Firebase/Play Services Version
1.0.1	10.0.0
1.0.0	9.8.0
0.6.2	9.8.0
0.6.1	9.6.1
0.6.0	9.6.0
0.5.3	9.4.0
0.4.4	9.4.0
0.4.3	9.2.1
0.4.2	9.2.0
0.4.1	9.0.2
0.4.0	9.0.0

Usage

Sample App

There is a sample app in the app/ directory that demonstrates most of the features of FirebaseUI. Load the project in Android Studio and run it on your Android device to see a demonstration.
