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.
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.
In the center of the project overview page, click the Android icon
(plat_android)
or Add app to launch the setup workflow.
Enter your app's package name in the Android package name field.
What's a package name, and where do you find it?
A package
name
uniquely identifies your app on the device and in the Google Play Store.
A package name is often referred to as an application ID.
Find your app's package name in your module (app-level) Gradle file,
usually app/build.gradle (example package name:
com.yourcompany.yourproject).
Be aware that the package name value is case-sensitive, and it cannot be
changed for this Firebase Android app after it's registered with your
Firebase project.
(Optional) Enter an App nickname, which is an internal, convenience
identifier that is only visible to you in the Firebase console.
Click Register app.
Step 3: Add a Firebase configuration file
Download and then add your app's Firebase config file
(google-services.json) to your codebase:
Click Download google-services.json to obtain your app's Firebase
config file.
Move your config file into the module (app-level) root directory of
your app.
What do you need to know about this config file?
The Firebase config file contains unique, but non-secret identifiers for
your project and app. To learn more about this config file, visit
Understand Firebase
Projects.
Make sure the config file name is not appended with additional characters,
like (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).
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"applyfalse// ...// Add the dependency for the Google services Gradle pluginid("com.google.gms.google-services")version"4.4.4"applyfalse}
Groovy
plugins{id'com.android.application'version'7.3.0'applyfalse// ...// Add the dependency for the Google services Gradle pluginid'com.google.gms.google-services'version'4.4.4'applyfalse}
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 pluginid("com.google.gms.google-services")// ...}
Groovy
plugins{id'com.android.application'// Add the Google services Gradle pluginid'com.google.gms.google-services'// ...}
Step 4: Add Firebase SDKs to your app
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 BoMimplementation(platform("com.google.firebase:firebase-bom:34.12.0"))// When using the BoM, you don't specify versions in Firebase library dependencies// Add the dependency for the Firebase SDK for Google Analyticsimplementation("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 Firestoreimplementation("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.
Analytics not enabled
dependencies{// ...// Import the Firebase BoMimplementation(platform("com.google.firebase:firebase-bom:34.12.0"))// 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 Firestoreimplementation("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.
After adding the dependencies for the products you want to use, sync your
Android project with Gradle files.
Are you getting a build failure about invoke-custom support and enabling
desugaring? Here's how to fix it.
Gradle builds that use Android Gradle plugin (AGP) v4.2 or earlier need to
enable Java 8 support. Otherwise, these Android projects get a build
failure when adding a Firebase SDK.
To fix this build failure, you can follow one of two options:
Add the listed compileOptions from the error message to your
app-levelbuild.gradle.kts or build.gradle file.
Increase the minSdk for your Android project to 26 or above.
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!
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
Open the Firebase Assistant: Tools > Firebase.
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).
Click Connect to Firebase to connect your Android project with Firebase.
What does this workflow do?
This workflow automatically creates a new Firebase Android app using
your app's
package name.
You can create this new Firebase Android app in either an existing
Firebase project or a new project.
Here are some tips about setting up your Firebase project:
Check out our
best practices
for adding apps to a Firebase project, including how to handle
multiple variants.
If you create a new project, we strongly recommend that you set up
Google Analytics for your project, which enables you to have
an optimal experience using many Firebase products.
This workflow also adds your Firebase project's Android
configuration file (google-services.json) to the module
(app-level) directory of your app.
Click the button to add a desired Firebase product (for example,
Add Analytics to your app).
Sync your app to ensure that all dependencies have the necessary versions.
In the Assistant pane, follow the remaining setup instructions for your
selected Firebase product.
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.
Note that when using the Firebase Android BoM,
you don't specify individual library versions when you declare Firebase library
dependencies in your Gradle build configuration file.
The latest Firebase BoM version contains the latest versions
of each Firebase Android library. To learn which library versions
are mapped to a specific BoM version, review the release notes
for that BoM version.
