The print preview UI owns and drives the lifecycle of several objects. These objects were torn down too late resulting in an attempt to use the activity as a context when it was no longer valid and service unbind resulting in causing a crash. Fixed a bug where if the back button is pressed mutiple times when the print UI is being initialized a crash occurs. bug:17454041 Change-Id: Ic1455b467586f0ad65f907e2160ec5cfb2d17d05
