Kind of off topic but why Mahout and not Weka and why on a mobile device. Mahout is built to be scalable for large datasets, not something you'd associate with a mobile device. On any mobile device you're going to run into memory issues very quickly with any sizable dataset. Even the Galaxy s3 only has max 256mb heap allowed (i think).
Personally I wouldn't even attempt such a thing, I'd off load the heavy lifting to a server and simply have the client mobile device request whatever it needed.
