Add Firebase to your Android project

Prerequisites

  • Install or update Android Studio to its latest version.

  • Make sure that your project meets these requirements (note that some products might have stricter requirements):

    • Targets API level 21 (Lollipop) or higher
    • Uses Android 5.0 or higher
    • Uses Jetpack (AndroidX), which includes meeting these version requirements:
      • com.android.tools.build:gradle v7.3.0 or later
      • compileSdkVersion 28 or later

  • Set up a physical device or use an emulator to run your app.
    Note that Firebase SDKs with a dependency on Google Play services require the device or emulator to have Google Play services installed.

  • Sign into Firebase using your Google account.

If you don't already have an Android project and just want to try out a Firebase product, you can download one of our quickstart samples.


You can connect your Android app to Firebase using one of the following options:

  • Option 1: (recommended) Use the Firebase console setup workflow.
  • Option 2: Use the Android Studio Firebase Assistant (may require additional configuration).


Option 1: Add Firebase using the Firebase console

Adding Firebase to your app involves tasks both in the Firebase console and in your open Android project (for example, you download Firebase config files from the console, then move them into your Android project).

Step 1: Create a Firebase project

Before you can add Firebase to your Android app, you need to create a Firebase project to connect to your Android app. Visit Understand Firebase Projects to learn more about Firebase projects.

Step 2: Register your app with Firebase

To use Firebase in your Android app, you need to register your app with your Firebase project. Registering your app is often called "adding" your app to your project.

  1. Go to the Firebase console.

  2. In the center of the project overview page, click the Android icon () or Add app to launch the setup workflow.

  3. Enter your app's package name in the Android package name field.

  4. (Optional) Enter other app information: App nickname and Debug signing certificate SHA-1.

  5. Click Register app.

Step 3: Add a Firebase configuration file

  1. Download and then add the Firebase Android configuration file (google-services.json) to your app:

    1. Click Download google-services.json to obtain your Firebase Android config file.

    2. Move your config file into the module (app-level) root directory of your app.

  2. To make the values in your google-services.json config file accessible to Firebase SDKs, you need the Google services Gradle plugin (google-services).

    1. In your root-level (project-level) Gradle file (<project>/build.gradle.kts or <project>/build.gradle), add the Google services plugin as a dependency:

      Kotlin 

      plugins {
  id("com.android.application") version "7.3.0" apply false
  // ...

  // Add the dependency for the Google services Gradle plugin
  id("com.google.gms.google-services") version "4.4.2" apply false
}

      Groovy 

      plugins {
  id 'com.android.application' version '7.3.0' apply false
  // ...

  // Add the dependency for the Google services Gradle plugin
  id 'com.google.gms.google-services' version '4.4.2' apply false
}

    2. In your module (app-level) Gradle file (usually <project>/<app-module>/build.gradle.kts or <project>/<app-module>/build.gradle), add the Google services plugin:

      Kotlin 

      plugins {
  id("com.android.application")

  // Add the Google services Gradle plugin
  id("com.google.gms.google-services")
  // ...
}

      Groovy 

      plugins {
  id 'com.android.application'

  // Add the Google services Gradle plugin
  id 'com.google.gms.google-services'
  // ...
}

Step 4: Add Firebase SDKs to your app

  1. In your module (app-level) Gradle file (usually <project>/<app-module>/build.gradle.kts or <project>/<app-module>/build.gradle), add the dependencies for the Firebase products that you want to use in your app. We recommend using the Firebase Android BoM to control library versioning.

    Analytics enabled 

    dependencies {
  // ...

  // Import the Firebase BoM
  implementation(platform("com.google.firebase:firebase-bom:33.5.1"))

  // When using the BoM, you don't specify versions in Firebase library dependencies

  // Add the dependency for the Firebase SDK for Google Analytics
  implementation("com.google.firebase:firebase-analytics")

  // TODO: Add the dependencies for any other Firebase products you want to use
  // See https://firebase.google.com/docs/android/setup#available-libraries
  // For example, add the dependencies for Firebase Authentication and Cloud Firestore
  implementation("com.google.firebase:firebase-auth")
  implementation("com.google.firebase:firebase-firestore")
}

    By using the Firebase Android BoM, your app will always use compatible versions of Firebase Android libraries.

    Looking for a Kotlin-specific library module? Starting in October 2023 (Firebase BoM 32.5.0), both Kotlin and Java developers can depend on the main library module (for details, see the FAQ about this initiative).

    Analytics not enabled 

    dependencies {
  // ...

  // Import the Firebase BoM
  implementation(platform("com.google.firebase:firebase-bom:33.5.1"))

  // When using the BoM, you don't specify versions in Firebase library dependencies

  // TODO: Add the dependencies for Firebase products you want to use
  // See https://firebase.google.com/docs/android/setup#available-libraries
  // For example, add the dependencies for Firebase Authentication and Cloud Firestore
  implementation("com.google.firebase:firebase-auth")
  implementation("com.google.firebase:firebase-firestore")
}

    By using the Firebase Android BoM, your app will always use compatible versions of Firebase Android libraries.

    Looking for a Kotlin-specific library module? Starting in October 2023 (Firebase BoM 32.5.0), both Kotlin and Java developers can depend on the main library module (for details, see the FAQ about this initiative).

  2. After adding the dependencies for the products you want to use, sync your Android project with Gradle files.

That's it! You can skip ahead to check out the recommended next steps.

If you're having trouble getting set up, though, visit the Android troubleshooting & FAQ.


Option 2: Add Firebase using the Firebase Assistant

The Firebase Assistant registers your app with a Firebase project and adds the necessary Firebase files, plugins, and dependencies to your Android project — all from within Android Studio!

  1. Open your Android project in Android Studio, then make sure that you're using the latest versions of Android Studio and the Firebase Assistant:

    • Windows / Linux: Help > Check for updates
    • macOS: Android Studio > Check for updates

  2. Open the Firebase Assistant: Tools > Firebase.

  3. In the Assistant pane, choose a Firebase product to add to your app. Expand its section, then click the tutorial link (for example, Analytics > Log an Analytics event).

    1. Click Connect to Firebase to connect your Android project with Firebase.

    2. Click the button to add a desired Firebase product (for example, Add Analytics to your app).

  4. Sync your app to ensure that all dependencies have the necessary versions.

  5. In the Assistant pane, follow the remaining setup instructions for your selected Firebase product.

  6. Add as many other Firebase products as you'd like via the Firebase Assistant!

That's it! Make sure to check out the recommended next steps.

If you're having trouble getting set up, though, visit the Android troubleshooting & FAQ.
