There are projects like eql5-android but you can't use the native Android gui library and have to stick with QT.
There is the Clojurescript approach but you will have to use React Native (which is developed by Facebook)
There is the Lispworks mobile runtime (I don't know how they achieved to create something like that, did they write their CL implementation in Java?) but it costs money.
There is kawa scheme but I'm not sure if it's as ready for real projects as something like Common Lisp or Clojure is.
Surely there must be an easier way right /prog/?
