Hi, JassimAlRahma-9056. Could you please post the related code about using the 'IFirebaseEvents'? Do you use DependencyService in your project? Pelase check the namespace of in implementation class on the native platform project.

[assembly: Xamarin.Forms.Dependency(typeof(Name Of Class))] namespace TestApplication_6.Droid { public class DroidImplementation : ITestInterface { } }

The error message implies you ar trying to use an interface like a class. Can you show where you are trying to use the interface?

DependencyService.Get<IFirebaseEvents>().LogEvent("MainPage");

Can you share your implementation of that interface? The class that uses it.
