This is a really nice project!
I've had experience with experimental integration of leap motion too, though it was simpler than getting data to android device, so hat off to you! What did you do to get data to android device? Used WLAN to send data? And how did you format your data? In my project, I formatted it in JSON format, so I can easily decode it in the 3. party software, and make use of the data.
Wish you good luck with the project!
