Remember, the goal of these challenges if for you to try new things. Just because you don't have a need for it, doesn't mean there isn't value in trying it. It may turn you on to a whole new arena that you never realized you enjoyed.
Indeed. I understand that. But because I have absolutely no use for an Android application, and don't see myself getting a device with Android on it in the foreseeable future, my personal projects are more important to me right now. It's got nothing to do with the challenge and everything to do with me. I'll probably kill this one off at the same time I kill the Java one off (polyglot programming anyone? ).
