Best and easier is just use React Native. I have a (stuck) personal project creating a video game in Android fully using Clojure. It works well, but the REPL is not supported. Also, unless you are experienced enough writing Android code, I think it's gonna be easier if you just write React. Another reason to not use Clojure on Android directly, is that Android is full of OOP, you won't enjoy Clojure as you should or maybe you will endup creating a lot of wrappers to give a more functional style to the code.
