presumably, drawer consists of expandablelistview explistview. if check asynctask's doinbackground() method, you'll see error_flag set 1 if there's no network available. then, in onpostexecute() method:
if (error_flag == 1) { explistview.setvisibility(8); a value of 8 corresponds view.gone, so, essentially, if there no network, there no drawer.
