Very basic games or for the business logic with the UI done in Java and XAML - C++/CX.

But if Clojure did support properly Android and CoreCLR, I would probably use it instead.

As things are, I might go Xamarin in the future.

if you want multiplatform support (or just really like c#/VS), xamarin can be a good choice for an hobby app.

Otherwise, Kotlin borrows many niceties with c# and allows you to directly use the platform APIs.
