I would look into ClojureDart for this to be honest. Clojure on android is very slow.

Haven't tried javafx on android though

what makes Clojure slow on android?

GC pressure

It generates too much garbage

Or was there a problem on Android with insanely long app boot times where most of the time is spent in Clojure loading namespaces?...

I also heard of recommendations to use react-native+cljs

here is another answer from 10 years ago about Clojure on Android — https://news.ycombinator.com/item?id=5471685

maybe the situation has changed, but to me it seems that there is just no Clojure on Android. But there is ClojureScript and ClojureDart

Aw that's sad to hear

Do you think this would be solved if there was native support for Clojure like Kotlin has?

Seems like a silly indirection to exist.
