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.

A compatible FirebaseUI client is also available for iOS.


FirebaseUI has separate modules for using Firebase Realtime Database, Cloud Firestore, Firebase Auth, and Cloud Storage. To get started, see the individual instructions for each module:


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 for Firebase Realtime Database
    implementation 'com.firebaseui:firebase-ui-database:4.1.0'

    // FirebaseUI for Cloud Firestore
    implementation 'com.firebaseui:firebase-ui-firestore:4.1.0'

    // FirebaseUI for Firebase Auth
    implementation 'com.firebaseui:firebase-ui-auth:4.1.0'

    // FirebaseUI for Cloud Storage
    implementation 'com.firebaseui:firebase-ui-storage:4.1.0'

If you're including the firebase-ui-auth dependency, there's a little more setup required.

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


If you are using an old version of FirebaseUI and upgrading, please see the appropriate migration guide:


Compatibility with Firebase / Google Play Services libraries

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





As of version 15.0.0, Firebase and Google Play services libraries have independent, semantic versions. This means that FirebaseUI has independent dependencies on each of the libraries above. For best results, your app should depend on a version of each dependency with the same major version number as the version used by FirebaseUI.

As of version 4.1.0, FirebaseUI has the following dependency versions:

Library Version
firebase-auth 16.0.1
play-services-auth 15.0.1
firebase-database 16.0.1
firebase-firestore 17.0.1
firebase-storage 16.0.1

Upgrading dependencies

If you would like to use a newer version of one of FirebaseUI's transitive dependencies, such as Firebase, Play services, or the Android support libraries, you need to add explicit implementation declarations in your build.gradle for all of FirebaseUI's dependencies at the version you want to use. For example if you want to use Play services/Firebase version FOO and support libraries version BAR add the following extra lines for each FirebaseUI module you're using:


implementation "$FOO"
implementation "$FOO"

implementation "$BAR"
implementation "$BAR"
implementation "$BAR"


implementation "$FOO"

implementation "$BAR"
implementation "$BAR"

Realtime Database

implementation "$FOO"

implementation "$BAR"
implementation "$BAR"


implementation "$FOO"

implementation "$BAR"
implementation "$BAR"


Starting version 25.4.0, support libraries are now available through Google's Maven repository, so ensure that you have that added to your project's repositories.

Open the build.gradle file for your project and modify it as following,

allprojects {
    repositories {

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.

Before you can run the sample app, you must create a project in the Firebase console. Add an Android app to the project, and copy the generated google-services.json file into the app/ directory. Also enable anonymous authentication for the Firebase project, since some components of the sample app requires it.

If you encounter a version incompatibility error between Android Studio and Gradle while trying to run the sample app, try disabling the Instant Run feature of Android Studio. Alternatively, update Android Studio and Gradle to their latest versions.

Snapshot builds

Like to live on the cutting edge? Want to try the next release of FirebaseUI before anyone else? As of version 3.2.2 FirebaseUI hosts "snapshot" builds on

Just add the following to your build.gradle:

repositories {
  maven { url "" }

Then you can depend on snapshot versions:

implementation 'com.firebaseui:firebase-ui-auth:x.y.z-SNAPSHOT'

You can see which SNAPSHOT builds are avaiable here:

Snapshot builds come with absolutely no guarantees and we will close any issues asking to troubleshoot a snapshot report unless they identify a bug that should block the release launch. Experiment at your own risk!
