After initializing the camera, and starting the scanning. If there is a phone call came in, the app is paused and backgrounded, in turn the scaning is pause.
Once the app is foregrounded and scanning restarted( not re-initialized), seems UPDATE_ERROR_NO_NETWORK_CONNECTION is never triggered even the device has no any connections(no wifi, and 3g).
Why the error status is not detected? or have to wait longer?
