[android-developers] trying to show a progressdialog in a lengthy task
Hi, When i first launch my main intent, i check if the application was updated and, if yes, i decompress some asset files. This task can take up to 15 seconds (to decompress a 6MB zip file). So, i was trying to show a ProgressDialog to the user. However, nothing in hell makes the dialog appear. The lengthy method is called from onCreate. I already tried to put it in onStart, but same thing. I also tried to run it in the ui thread, same thing: no dialog appears, even if isShowing returns true. This is the code: showProgressDialog while (...) // a 15-second task nowQuit(); What can i do to make the dialog really show up on screen? thanks guich -- You received this message because you are subscribed to the Google Groups Android Developers group.

Use an AsyncTask or an IntentService. -- Mark Murphy (a Commons Guy) http://commonsware.com | http://twitter.com/commonsguy Android Training in US: 14-18 June 2010: http://bignerdranch.com -- You received this message because you are subscribed to the Google Groups Android Developers group.
