The main problem which you will get with languages like Scala , Clojure and other functional languages on JVM is a lot of garbage generated during the execution. And garbage collector on Android isn't even remotely as effective as standard one. This often forces you to write code which is not really idiomatic and which rather resembles java. That is possible in Scala (I'm not sure about Clojure), but to some extend it defeats whole purpose of using something other than java.
