I am planning to introduce Firebase to add a push notification function to the game I made with Unity.

I pasted the application-specific google-services.json in the Asset folder,
I installed FirebaseMessaging.unitypackage of SDK downloaded from here, but I get an error.

Console

Unloading broken assembly Assets/Firebase/Plugins/Firebase.App.dll, this assembly can cause crashes in the runtime

You can start to diagnose this issue by executing "C:/UnityProjects/Test/Assets..AssetsFirebaseEditorgenerate_xml_from_google_services_json.exe -i "Assets/google-services.json" -l." from the command line.

I'd like to add this;

public void Start() {

  Firebase.Messaging.FirebaseMessaging.TokenReceived += OnTokenReceived;

  Firebase.Messaging.FirebaseMessaging.MessageReceived += OnMessageReceived;

}

but due to errors, I get errors on the OnTokenReceived and OnMessageReceived parts.

Do these have problems with google-services.json created with Firebase for applications?
Anyone please solve me.

Check your Project Settings > IOS. Make sure the .NET is 4.X not 3.

I was facing the same error and find an answer from the Firebase's Github. Here is the post from the Github:

All "Unloading the assembly" does is unload the DLL from the app
domain (i.e Unity's process) then disable the platform targeting
options. So what you'll need to do is select the unloaded DLL(s) and
in the plugin inspector tick the platform check boxes to re-enable
them for the appropriate platform.

We typically follow the pattern to enable target platforms:

Firebase/*.dll : Target Android, Editor, Standalone - with the
exception of FIrebase.Database.dll Firebase/Firebase.Database.dll
: Target Android-only Firebase/iOS/*.dll : Target iOS
Firebase/Mono/Firebase.Database.dll : Target Editor, Standalone

Here is the link: https://github.com/firebase/quickstart-unity/issues/256

Hope it helps.

I ran into this problem with a freshly created project. The project was targeting Android and I was loading the dotnet4 version of the assembly. I switched to the dotnet3 version and it fixed the issue. I noticed that the Script Runtime Version targets .NET 3.5 Equivalent by default. I'm brand new to Unity, so I'm not sure if that's the issue.
