PresentationUI is part of WPF (UI framework on Windows), which is not available on mobile platforms, such as Xamarin.Android.
You have to recreate a mobile compatible UI of your application so as to be Android ready.
Microsoft designs Prism to work with WPF, so yes you cannot use it in a Xamarin.Android project. (Prism latest build does work with Xamarin Forms though).
