Actually, with Android Scripting (http://code.google.com/p/android-scripting/ http://code.google.com/p/android-scripting/) you can use other languages that run on jvm, such as ruby, python, javascript and others. Charles Nutter even supports a ruby version on Android directly: http://blog.headius.com/2010/01/busy-week-jruby-with-android-maven-rake.html http://blog.headius.com/2010/01/busy-week-jruby-with-android.... If you like static typed languages, you can even use Scala on Android (http://www.scala-lang.org/node/160 http://www.scala-lang.org/node/160). Many possibilities beyond plain old java.
