If you already use Maven, developing a Android application isn't going to be a stretch. There's a very active community of open source projects for maven-droid development, and the Android SDK artifacts are available on Central.
You've probably noticed increased advertising for Google's Android platform over the past few months. The mobile wars are heating up with the release of iPhone 4 and Android-based phones seem to be gaining market share at a rapid pace.
