Need help > FirebasePushNotificationsPlugin : Default FirebaseApp is not initialized in this process

Hi all,

I updated to the latest version (3.3.10) but now I get this error on Android (working on iOS):

**Java.Lang.IllegalStateException:** 'Default FirebaseApp is not initialized 
in this process com.companyname.firebasetest. 
Make sure to call FirebaseApp.initializeApp(Context) first.'

The error occurs when this FirebaseMessaging.Instance is called.

I found some solutions that does not work for me:

• My google-services.json has the GoogleServicesJson build action (tried to put it to none again then GSJson)
• My firebase android app package name is the same package name on my Android project.
• I updated android’s tools
• I updated XF and so on
• Google APIs and Play Store checked
• Permissions allowed (internet, etc.)
• Also tried to add this line: FirebaseApp app = FirebaseApp.InitializeApp(Android.App.Application.Context);

PS:

• I created a new project (and new firebase project) but I get the same error
• I pulled the sample of the FirebasePushNotification Plugin, and still getting the error
• Notifications was working with version 2.3.x

What can I do ? I need help

Thank you guys

It seems that the build action for the GoogleServicesJson is not working correctly. As a workaround initialising firebase as described in this post worked for me: https://stackoverflow.com/a/51381884
