The use case is that the user should always see the loading progressbar if
there's any background work being done in whatever activity the user is and
if the task was launched from another activity. I tried putting a reference
in the application class to the progressbar and then refresh it in the
activities in the oncreate and onrestart,that the way the task will always
have the refreshed reference on the postexecute method....
Any inconvinients on this procedure?

regards,
