I just built my first Android device and was trying to find a way for it to stream to the AxiomAir. I found this free program (AllConnect - Play & Stream) that works great:https://play.google.com/store/apps/details?id=com.tuxera.streambels
When you run it, it sees all Airplay devices (AppleTV, AxiomAir, etc.) and you can directly stream music from your device to the speaker. I needed to do it this way because my main device is an iPhone, and I wanted to keep the AxiomAir on the network as-is.
So, for anyone who has both iPhone and Android, and wants to be able to stream to the AxiomAir with both, this program is very nice.
