Usage

FirebaseUI consists of different modules tailored for various Firebase services including Firebase Realtime Database, Cloud Firestore, Firebase Auth, and Cloud Storage. To start using FirebaseUI, explore the individual instructions for each module:

• FirebaseUI Auth
• FirebaseUI Firestore
• FirebaseUI Database
• FirebaseUI Storage

Installation

FirebaseUI libraries are divided based on the Firebase services they target. You don’t need to include Firebase SDKs separately, as each FirebaseUI library encompasses these dependencies. To add FirebaseUI to your app, include the following lines in your build.gradle file:

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'
}

Upgrading

If you are upgrading from an older version of FirebaseUI, refer to the appropriate migration guide available on the documentation site.

Dependencies

Compatibility with Firebase & Google Play Services Libraries

FirebaseUI libraries rely on the following Firebase SDKs:

• firebase-ui-auth — com.google.firebase:firebase-auth and 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

Upgrading Dependencies

To use a newer version of FirebaseUI’s transitive dependencies, you will need to add explicit declarations for all of them in your build.gradle. Here’s how you’d go about it:

// Auth
implementation 'com.google.firebase:firebase-auth:$X.Y.Z'
implementation 'com.google.android.gms:play-services-auth:$X.Y.Z'
// Firestore
implementation 'com.google.firebase:firebase-firestore:$X.Y.Z'

Sample App

A sample app is available in the app directory to demonstrate FirebaseUI features. To run it, create a project in the Firebase console, add your app, and copy the google-services.json file into your app directory. Be sure to enable anonymous authentication as it’s necessary for some components of the sample app.

Snapshot Builds

If you’re eager to try the cutting-edge features of FirebaseUI, snapshot builds are available. Add the following to your build.gradle:

repositories {
    maven {
        url 'https://oss.jfrog.org/artifactory/oss-snapshot-local'
    }
}

Contributing

Installing Locally

You can install FirebaseUI locally by cloning the repository and running the following command:

sh gradlew :library:prepareArtifacts publishToMavenLocal

License Agreements

To contribute solutions to FirebaseUI, you will need to sign a Contributor License Agreement (CLA). Instructions for signing CLA based on your status (individual or corporate) can be found in the project documentation.

Process

The normal contribution process consists of submitting an issue, checking for acceptance from the repo owner, making required changes, and ensuring adherence to coding style and unit tests before submitting a pull request to the latest dev branch.

Troubleshooting

While setting up FirebaseUI, you may encounter some issues, such as version incompatibility between Android Studio and Gradle, or importing the project via Android Studio. In case you do face compatibility errors, you can try disabling InstantRun or ensure your software is updated to the latest version. Remember that using “Project from Version Control” may not automatically connect your project with Gradle—import it from external models instead.
