Which programming languages can I use on Android Dalvik?
1) Angular + nativeScript
2) Reactnative
In theory, Dalvik executes any virtual machine byte code, created for example with the compilers of 

AspectJ
ColdFusion
Clojure
Groovy
JavaFX Script
JRuby
Jython
Rhino
Scala

Are there already working versions of bytecode compilers for Dalvik available for other languages than Java?
