    When my application is running, I go through the Android Settings shortcut and turn off the Airplane mode. I can see that as soon as the data connection is established, the application died and restart automatically but the restart fails and I have only a white screen instead of my application main view. Following is the error Log. Any help would be very appreciated. Thanks.

      Did you get any solution?
      I am having the same problem when unplugging a touch screen USB connection on an Android BOX.
