Yet another paiunful XE16 discovery, ADB over TCP is broken. On modern Android devices, we get that dialog that asks if we want to allow USB debugging.
On Glass, they removed that.... And removed the check when connecting via USB. The check while connecting via TCP is still there
C:\Users\Michael>adb -s 172.25.7.140:5555
error: device unauthorized. Please check the confirmation dialog on your device.
Basically this means, developers are now tethered to their machines via a USB cable and Tilt Control is broken using non-rooted methods.
