The Unity Distribution Portal (UDP) is shutting down on February 17th, 2025. Access to the UDP Web console and services will be permanently deactivated on this date. To download your keystores and instructions on how to republish your games directly to app stores, visit the UDP overview page. If you have any questions about your account, submit a ticket with Unity Customer Support. |
Implementing Firebase in your Android games lets you leverage the Firebase product layer, for example for analyticsAbbreviation of Unity Analytics
See in Glossary or crashlytics. If your game uses Firebase, additional configuration is required to support the builds that Unity Distribution Portal (UDP) creates for different stores.
When your app invokes Firebase products, Firebase checks that the following information matches the details registered on the Firebase console:
These details must match in order for Firebase to provide accurate analysis.
For certain stores where you publish your game via UDP, UDP adds a store-specific suffix to the package name. Additionally, if you don’t use your own private key to generate the certificate, UDP generates a certificate for each repacked build. These events would cause your certificate and/or package name to no longer match the information on the Firebase console.
The UDP console displays a warning for Firebase services if you register your app to stores that need a package name suffix.
To enable your store-specific builds to work correctly with Firebase, you must register them with your Firebase project. The following sections explain how to configure Firebase for your UDP builds.
This section gives an overview of the steps required to configure Firebase for your UDP builds (apps). For more detailed information, see the Firebase documentation.
Note: During the process to register your app, you can download a google-services.json file. Unity recommends that you register all your package versions before you download this file.
keytool -keystore path-to-your-keystore -list -v
openssl x509 -in path-to-your-certificate -fingerprint -noout
Repeat these steps for each store-specific app you want to link to your Firebase project. Firebase adds an App ID for each app you add.
When you’ve registered all your apps, add the Firebase configuration file to your Unity project.
When you register an app in Firebase, Firebase creates a google-services.json configuration file. When you’ve added all your apps to Firebase, download the file and add it to your project.
Your project is now properly configured for Firebase. To ensure stable operation of your app, rebuild and publish your project.
For each build you’ve added to Firebase, in the UDP console, add the App ID:
