I'm using Flash Builder 4.6 with Apache Flex SDK 4.9.1 for building an Android application in Windows 7.
The debug in my Android tablet, a Sony Tablet S (SGPT111CO/S) used to work perfectly.
All of the sudden (I think because of an AIR runtime automatic update in the tablet), the device stopped communicating with the Flash Builder either for debugging or for playing the application.
Sometimes (usually the first time), Flash builder says:
"Device appears to be offline. Restarting the device may fix the problem"
Other times (usually the second and following times), it just doesn't show the device, and says:
"Flash builder could not find a connected device"
I'm running out of ideas, as nothing seems to work.
