I do not have rep to comment, is wifly a serial interface?
Second, this is a good place to ask that, I understood they were inviting developers here.
Extra, after comment reply
As far as I have found there is no ability for serial from the android phones.
I have found sources where people mod the OS to support USB on the Go. Then you can be a USB host, which would suffice for me as usb to serial adapters are relatively easy to come by.
I am new to android and spend most my time on the Electronics and Robotics SO site, but I was interested in this feature.
