The Motorola Atrix is on the list of supported devices on the main page, yet when I'm trying to use any of the sample projects with it I get the Network Connection Required error message. I have a Xperia x10 and everything is working fine on it, so the problem seems to be specific to the Atrix.
Running Android 2.2.1 on both of them, with no Sim cards but connected to a Wi-Fi network. Both are connected to my computer via USB.
Anything I can do to make it work? Would hate to tell my boss he just bought a phone that doesn't even work with our latest project... :)
