Hi,
I need to add the support to firebase Crashlytics to my Xamarin.forms app.
For iOS it seems to work but on Android doesn't.
I need to have multiple json config files so I used this code to load the configuration:
FirebaseOptions options = new FirebaseOptions.Builder()
.SetApplicationId(applicationId)
.SetApiKey(apiKey)
.SetGcmSenderId(gcmSenderId)
.SetProjectId(projectId)
.SetStorageBucket(storageBucket)
//.SetGaTrackingId("")
.Build();
FirebaseApp.InitializeApp(this, options);
but after I have added the Firebase Crashlytics nuget pack, this error is triggered:

How can I solve this?
Also, there is an update guide to use Firebase in a Xamarin Forms application?
I have found only very old post to do so, but all with some older version of Firebase NuGet packages (ex. they use fabric or an old namespace).
Thank you!
