Device appears to be offline. Restarting the device may fix the problem.

With Flash Builder 4.7 and Flex SDK 4.6 with AIR SDK 3.6 after my Google Nexus 10 upgraded to Android 4.2.2 I now get this error when attempting to launch to the device from Flash Builder:

Device appears to be offline. Restarting the device may fix the problem.

It showed Adobe AIR as Not Installed so I uninstalled it from the device and that didn't fix anything. I have tried everything. Rebooting the device. Rebooting Flash Builder. Rebooting Windows. Nothing helps.

Anyone know how to fix this?

Just to add another solution in case the others listed here don't work for someone...

Hardware: Windows 7 and Nexus 7(original) with Android 4.4.4

I had the latest version of Flash CC 2014 installed that also included the necessary updated files. I only needed to update aapt.exe and adb.exe.

Copied aapt.exe and adb.exe from \Program Files\Adobe\Adobe Flash CC 2014\AIR14.0\lib\android\bin\

To \Program Files\Adobe\Adobe Flash Builder 4.7 (64 Bit)\sdks\4.6.0\lib\android\bin

The same two files are also located in the FlashBuilder directory \Program Files\Adobe\Adobe Flash Builder 4.7 (64 Bit)\eclipse\plugins\com.adobe.flash.compiler_4.7.0.349722\AIRSDK\lib\android\bin but I did NOT replace those file instances, only the instances in the sdks\4.6.0\... directory. Can't explain it because I am using the Flash Builder/eclipse IDE to run/download the app to the Android device.

This is what worked for me. Your mileage may vary.

BTW: It's telling that Flash Builder hasn't been updated for over two years to solve this simple problem. Not even a solution post from an Adobe representative can be found here. Flash Builder is part of my CC Cloud subscription, so regular updates should be provided, but Builder is clearly not receiving even minimal development resources from Adobe.This is end-of-life technology.
