How can we use languages like Ada, Rust or Erlang to program Android Apps??

Answer 1

Well since Java is the most popular language and Android Studio is popular too, they use it however you can still build in Rust (Can be on Android) not sure on Erlang and Ada. But dont get it wrong Rust aint a stupid language, its new and good

Answer 2

i think they are not the best languages for building Android apps, Java is the​ optimal option.
