How do I cache? I did some investigation, and the steps that seem to take a lot of time is displaying of the app name/icon and whether it's a system app or not, i.e. getting the following results: 1. applicationInfo.loadLabel().toString() 2. applicationInfo.flags 3. applicationInfo.loadIcon() How do I cache when it's the first time that I'm running the app and it's generating a new list? > > > 2.

Currently I have a main activity which extends a TabActivity class, and in it I have a few tabs, which extends ListActivity classes. So I should generate the app list in the TabActivity's onCreate() method, and access the list from the tabs?
