Okay, then it isn't seeing stuff from AppGameKit (which is your original complaint, so no surprise, but asking is part of the process).
I have an Android 4.1.1 Samsung Galaxy S III and it picks up broadcasting okay.
A dumb question now, is your device in Airplane mode by any chance?
Another, when you look at the wireless network it is using, are you sure it is saying exactly the same as on your phone?
And (grasping at straws), have you tried totally powering it down and then restarting it and trying the broadcasting?
