FirebaseUI for Android — UI Bindings for Firebase

FirebaseOpensource.com Actions Status

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:

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!
