I cannot speak for anyone else, but I saw and skipped your previous messages because you insist upon cross-posting to multiple lists, and I get tired of it. Please only post to one list at a time. You also reposted this twice within the past few hours. If you want that fast of a response, please hire a consultant. >>> The scenario is, I have an AsyncTask inside an activity_A.

The user might have exited your activity, for example. I am not aware of a 100% reliable way to raise a dialog triggered asynchronously, such as in onPostExecute(). One approximate answer is to have the activity register a listener object with the service (e.g., in onCreate()) and unregister itself later (e.g., in onDestroy()). The service would call a method on the listener object (if it is not null) to have the listener/activity raise the dialog. -- Mark Murphy (a Commons Guy) http://commonsware.com Android App Developer Books: http://commonsware.com/books.html --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Android Beginners" group.
