Ignoring everything else, you should do the work in an async task. 3 seconds is a *LONG* time. Seriously, it's a really really long time. When you are sitting there interacting with your phone and it sits there frozen for 3 seconds, that's an eternity.
Once you have that out of the way, it's just a matter of deciding what you want to do in the UI during the time you don't have your final data to display to the user. One approach is to just have a progress indicator embedded in the UI that is shown while waiting for the data -- see for example the music picker: http://android.git.kernel.org/?p=platform/packages/apps/Music.git;a=blob;f=src/com/android/music/MusicPicker.java;h=c41746ddf2cbeb80e111d72139b42e8f01329c30;hb=HEAD#l565 On Mon, Nov 1, 2010 at 6:34 PM, Bret Foreman <[email protected]> wrote: > I'm working on the same issue.
