the mutual reason error message activity dialog shown on has been closed prior dismissing dialog - causing leaked window.
in scenario, introducing asynctask, there might possibility activity executed task has been terminated prematurely. example: back-key pressed user, no-history attribute in manifest activity or due other reasons.
there might possibility finishing activity right-after executing async task. in case, dialog cannot survive parent window terminated.
for safeguard, suggest include dialog.setcancelable(false); dialog. block user finishing activity. 1 time dialog dismissed after reaching onpostexecute, user allowed finish activity. or create sure not finishing activity async task reached onpostexecute.
or alternate take dialog out asynctask , attach activity's life cycle may dismiss dialog in ondestroy on activity.
