Re: [android-developers] Re: Async Task, rotation and indeterminate progressbar in custom header.

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,

AsyncTasks are a nifty tool but they have a fairly limited specific
set of uses.  The previous responses have pointed out a several
problems with this code: you can't keep static refs to Activites or
Views, multiple Activities can't share a progress bar, etc.

I don't understand the use case, but I agree with Mark that, from the
code you've supplied, this might be better done as an IntentService or
as a pair of Fragments.

I'm going to be giving a Webinar on the pitfalls surrounding
AsyncTasks next week, on the 29th:
