For others considering Rust + Kotlin for native Android development, there's also the Visly blog post[1] with basic steps. However, since then, Google officially released `androidx`. Unfortunately, Android Studio or the SDK lack `cargo fix` features of modifying your source code and instead just magically compiles with a compatibility layer. There's a PR on Visly's GitHub repo with these code fixes.
Also, their code base is minimal: does just enough with Rust shared library to have an app generate a log message. That's enough if you already know Android development.
For a complete end-to-end example search query screen with results screen (Activity, Fragment) using Rust, Kotlin, androidx, RecyclerView, ViewModel, etc., there's [2], but it was written while learning all things Android.
Perhaps it might help someone out there!

Edit: Yes, that second one is mine. Had fun learning but hopefully will never have to touch mobile dev again beyond maybe a PWA. (I'm a server-side dev.)
