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.

Usage
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:
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 for Firebase Realtime Database
implementation 'com.firebaseui:firebase-ui-database:8.0.2'
// FirebaseUI for Cloud Firestore
implementation 'com.firebaseui:firebase-ui-firestore:8.0.2'
// FirebaseUI for Firebase Auth
implementation 'com.firebaseui:firebase-ui-auth:8.0.2'
// FirebaseUI for Cloud Storage
implementation 'com.firebaseui:firebase-ui-storage:8.0.2'
}
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.
Upgrading
If you are using an old version of FirebaseUI and upgrading, please see the appropriate migration guide:
- Upgrade from 7.2.0 to 8.x.x
- Upgrade from 6.4.0 to 7.x.x
- Upgrade from 5.1.0 to 6.x.x
- Upgrade from 4.3.2 to 5.x.x
- Upgrade from 3.3.1 to 4.x.x
- Upgrade from 2.3.0 to 3.x.x
- Upgrade from 1.2.0 to 2.x.x
Dependencies
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-firestore
|--- com.google.firebase:firebase-firestore
firebase-ui-storage
|--- com.google.firebase:firebase-storage
You can see the specific dependencies associated with each release on the Releases page.
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. Here are some examples listing all of the critical dependencies:
Auth
implementation "com.google.firebase:firebase-auth:$X.Y.Z"
implementation "com.google.android.gms:play-services-auth:$X.Y.Z"
implementation "androidx.lifecycle:lifecycle-extensions:$X.Y.Z"
implementation "androidx.browser:browser:$X.Y.Z"
implementation "androidx.cardview:cardview:$X.Y.Z"
implementation "androidx.constraintlayout:constraintlayout:$X.Y.Z"
implementation "androidx.legacy:legacy-support-v4:$X.Y.Z"
implementation "com.google.android.material:material:$X.Y.Z"
Firestore
implementation "com.google.firebase:firebase-firestore:$X.Y.Z"
implementation "androidx.legacy:legacy-support-v4:$X.Y.Z"
implementation "androidx.recyclerview:recyclerview:$X.Y.Z"
Realtime Database
implementation "com.google.firebase:firebase-database:$X.Y.Z"
implementation "androidx.legacy:legacy-support-v4:$X.Y.Z"
implementation "androidx.recyclerview:recyclerview:$X.Y.Z"
Storage
implementation "com.google.firebase:firebase-storage:$X.Y.Z"
implementation "androidx.legacy:legacy-support-v4:$X.Y.Z"
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.
A note on importing the project using Android Studio: Using 'Project from
Version Control' will not automatically link the project with Gradle
(issue #1349).
When doing so and opening any build.gradle.kts
file, an error shows up:
Project 'FirebaseUI-Android' isn't linked with Gradle
. To resolve this
issue, please git checkout
the project manually and import with Import from external model
.
Snapshot builds
Like to live on the cutting edge? Want to try the next release of FirebaseUI before anyone else? FirebaseUI hosts "snapshot" builds on oss.jfrog.org.
Just add the following to your build.gradle
:
repositories {
maven { url "https://oss.jfrog.org/artifactory/oss-snapshot-local" }
}
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:
https://oss.jfrog.org/webapp/#/artifacts/browse/tree/General/oss-snapshot-local/com/firebaseui
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!

Installing locally
You can download FirebaseUI and install it locally by cloning this repository and running:
./gradlew :library:prepareArtifacts publishToMavenLocal
Contributor License Agreements
We'd love to accept your sample apps and patches! Before we can take them, we have to jump a couple of legal hurdles.
Please fill out either the individual or corporate Contributor License Agreement (CLA).
- If you are an individual writing original source code and you're sure you own the intellectual property, then you'll need to sign an individual CLA.
- If you work for a company that wants to allow you to contribute your work, then you'll need to sign a corporate CLA.
Follow either of the two links above to access the appropriate CLA and instructions for how to sign and return it. Once we receive it, we'll be able to accept your pull requests.
Contribution process
- Submit an issue describing your proposed change to the repo in question.
- The repo owner will respond to your issue promptly.
- If your proposed change is accepted, and you haven't already done so, sign a Contributor License Agreement (see details above).
- Fork the desired repo, develop, and then test your code changes on the latest dev branch.
- Ensure that your code adheres to the existing style of the library to which you are contributing.
- Ensure that your code has an appropriate set of unit tests which all pass.
- Submit a pull request targeting the latest dev branch.
