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.

When setting up surveillance cameras, the installed lens may not necessarily be the best one for the job. The focal length of the lens helps to determine how far from and how wide of a viewing target you can have. If you know the CCD Image Sensor Size, the Distance to the Target, and the Width of the Target, you can calculate the Lens Focal Length and the Horizontal Viewing Angle. Visit our CCTV Lens Calculator page, enter your values, and press the “Calculate” button.
