What languages are mature to develop native apps in Android [except Java]

Question

Is there a languages other then Java to develop native apps in android without script layer/AIR and others 3rd party abstractions.

Mostly im interested in Clojure,JRuby, Scala

Answer 1

Since Scala is compiled to native JVM bytecode, it could be use to develop native Android apps.

The biggest problem is that using 3rd party library is not that easy in Android development, and you need use proguard to reduce the size of your program, sometimes this will cause problem.

But it is still feasible to develop an Android app using Scala, for example, I've wrote an little android app (page in Chinese, but there is screenshots) using Scala. It's not a complex app, but should demonstrate what Scala could do in Android app development.

Here is also an SBT plugins that help you build your Scala/Android program.

Finally, if you want develop Android using Scala, I will suggest using Scala 2.8.x. I found my program crashes during adb install when I extends a collection class using Scala 2.9.
