     28 //    necessary until the Error property is set so that the correct
     29 //    message can be displayed.

     31 //    notification system, generate a notification immediately, and update
     32 //    it when the Error property is set to guarantee that a notification is
     33 //    displayed for every failure.
     34 // 2. It observes NetworkState changes to generate notifications when a
     35 //    Cellular network is out of credits.
