An error may occur if Firebase SDK or google-services.json file was not installed properly.
Make sure to check if the value is a randomly-generated string value via Backend.Android.GetDeviceToken().
When string.Empty appears, reinstall Firebase SDK or the JSON file by following the steps below:

  • Re-import FirebaseMessaging.unitypackage
  • Organize plugins(Assets > External Dependency Manager > Android Resolver > Force Resolve)
  • Check if Firebase's package name settings match Unity's package name settings
  • Re-apply the google-services.json file provided by Firebase
