¿Puedo obtener una devolución de llamada en la clase de aplicación siempre que se inicie una nueva actividad en toda la aplicación?

Aquí está el ejemplo perfecto

https://github.com/BoD/android-activitylifecyclecallbacks-compat/blob/master/example-project/src/org/jraf/android/util/activitylifecyclecallbackscompat/example/Application.java

Parece que este código en Xamarin Android (C #)

https://developer.android.com/reference/android/app/Application.ActivityLifecycleCallbacks.html

es poco similar a lo que estoy buscando
