Runtime error when creating Crashlytics instance in Android

[technohead]

Hi,
I'm getting the following crash when creating the initial Crashlytics object:

Java.Lang.ClassNotFoundException

Didn't find class "com.crashlytics.android.beta.Beta" on path: DexPathList[[zip file "/data/app/com.adrides.adrides-ZclmSlBn9yAOZ4IlmHUhrw==/base.apk"],nativeLibraryDirectories=[/data/app/com.adrides.adrides-ZclmSlBn9yAOZ4IlmHUhrw==/lib/x86, /data/app/com.adrides.adrides-ZclmSlBn9yAOZ4IlmHUhrw==/base.apk!/lib/x86, /system/lib, /vendor/lib]]

Here is my code:

Firebase.FirebaseApp.InitializeApp(this);
var crashlytics = new Crashlytics.Crashlytics(); // crash occurs here

The version of the Xamarin.Android.Crashlytics is 2.9.4.1.
I've tried building with and without multi-dex and still see the same issue.

My VS environment is as follows:

Hi there, I got the same type of error, even with the 2.9.4.4 version of Xamarin.Android.Crashlytics.

Java.Lang.ClassNotFoundException: 'Didn't find class "com.crashlytics.android.Crashlytics" on path: DexPathList[[zip file "/system/framework/org.apache.http.legacy.boot.jar", zip file "/data/app/ei.TeamUp--vCfa4WLP7cC1pBZEsPojg==/base.apk"],nativeLibraryDirectories=[/data/app/ei.TeamUp--vCfa4WLP7cC1pBZEsPojg==/lib/arm64, /data/app/ei.TeamUp--vCfa4WLP7cC1pBZEsPojg==/base.apk!/lib/arm64-v8a, /system/lib64]]'

I tried severals things, try to install dependencies manually, change the version, add Xamarin.Android.Crashlytics.Core, nothing change.

The Multi-Dex is already activated, but the Proguard is not.

Any advices or help?
