This article reviews the common issues you may encounter when linking your AdMob app(s) to Firebase, and the resources you can use to troubleshoot those issues.
What linking issues are you having with Firebase?
- Can't link to Firebase. Check your permissions.
- Can't link your app to Firebase. Refresh the page and try again.
- Reached the limit of projects in Firebase
- Failed to create a new Firebase project
- Failed to create a new Firebase app
- Don’t have access to Google Analytics for Firebase from this AdMob account
- Another user on this account has already obtained access to Google Analytics for Firebase
Can't link to Firebase. Check your permissions.
To link an AdMob app to Firebase, you must have the following permissions for AdMob, Firebase, and Google Analytics:
- In AdMob, you must have administrator permissions to link an app to Firebase.
-
In Firebase, you must have the '
firebase.links.create'IAM permission. This permission is included in the Owner role and the Firebase Admin role. If you don't have either of these roles, you can ask a project owner to assign one of these roles to your account via the Firebase console IAM settings. - In Google Analytics, you must have the Edit role or Manage Users role for the property associated with the Firebase project. Learn more about access and data-restriction management.
Can't link your app to Firebase. Refresh the page and try again.
AdMob had problems connecting to Firebase when you tried to link your app. Refresh the page and try linking your app again.
If you still have issues:
- Confirm that you're using the same email address for both AdMob and Firebase.
- Confirm that the project you're linking to hasn't been deleted.
Reached the limit of projects in Firebase
There is a limit to the number of projects a Firebase account may create. If the limit has been reached, you'll receive an error when you try to link an AdMob app to a new project.
This error is most commonly triggered if you try to create more than 11 projects within the first 24 hours of linking your first AdMob app to Firebase.
Failed to create a new Firebase project
A new Firebase project couldn’t be created at this time. For example, this may mean that AdMob had trouble connecting to Firebase, or your Firebase account may have reached the project limit.
Failed to create a new Firebase app
A new Firebase app couldn’t be created at this time. For example, this may mean that AdMob had trouble connecting to Firebase, or an app with the same package ID already exists in your Firebase project.
Don’t have access to Google Analytics for Firebase from this AdMob account
Another user has already linked an app from your shared AdMob account to Firebase, but you haven’t been granted access to the Google Analytics for Firebase data.
To gain access to the Google Analytics for Firebase data, you need to contact that user and ask them to grant you access through the Firebase console.

Another user has already linked an app from your shared AdMob account to Firebase, but you haven’t been granted access to the Google Analytics for Firebase data.
