IntelliJ Android IDE Going Open
IntelliJ IDEA 10 (X) is expected to be released later this fall. The community edition, first released in version 9, features plugins for Scala, Clojure, Java ME, and OSGi development. Android development was only supported in the commercial edition, but expect that to change in IntelliJ X.
