Adobe Flash Builder shows device offline after updating to android 4.2.2

The reason that the device is listed as offline is because of a new security requirement of Android 4.2.2 when debugging to the device. I updated my phone to android 4.2.2 yesterday and the attempted to use Flash Builder this morning and found that my device was listed as being offline. I first tried following the instructions to update to Adobe AIR 3.6 SDK & Compiler, but this did not fix the offline trouble. Follow these steps so that you can debug to your device running Android 4.2.2:

  • Download Android SDK Platform-tools using the Android SDK Manager.
  • Navigate to the newly installed platform-tools directory. (Mine was found @ C:\Users\kevin.godell\AppData\Local\Android\android-sdk\platform-tools).
  • Copy the adb.exe file.
  • Navigate to the directory that contains the adb.exe currently in use by Flash Builder (Mine was found @ C:\Program Files\Adobe\Adobe Flash Builder 4.7\sdks\4.6.0\lib\android\bin).
  • Make a backup copy of your existing file adb.exe (adb-backup.exe).
  • Paste your new adb.exe that you copied from the platform-tools directory.
  • Attempt to debug to your Android device and you will be prompted to accept the security key.
  • Good luck. It took me an hour of wasted time to get this figured out.
