[Heads Up] ADB from the Xoom
Just a heads up, the Xoom can run ADB natively. Full ADB. Haven't tested it over USB Host, but it works with ADBwireless.
Doesn't seem to be documented anywhere, but it does work. Try ADB devices from a terminal on your xoom.
Meaning that the Xoom can run ADB, just like your computer. Pull APKs, ringtones, media, whatever over wifi.
EDIT: These commands should make it work without the apk.
To trigger adb wifi on your phone/non-Xoom:
setprop service.adb.tcp.port 5555
To stop adb wifi and return to USB listening:
setprop service.adb.tcp.port -1
adb connect [IPAddress]:[port]
For example, adb connect 192.168.1.4:5555
Or from USB on your comp:
adb tcpip 5555
adb connect 192.168.0.101:5555
To get back to USB mode:
