I have just released the first version of DronePro for Android priced at $5 in the Play Store.
It is ground control software designed to allow gamepad control of 3DR Pixhawk based drones (tested with Iris / Iris+ and Y6B).
It has full control of GoPros when connected to the GoPro wifi - turning on; video recording etc.
It also supports USB UVC video capture, so you can display FPV video streams and locally record it.
More details on my website with a link to the Play Store entry and a Google+ group.
I am only developing this in my spare time, and hope to cover the development costs (icons are ridiculously expensive... and so are drones and spares when you crash).
