Android ActionBar Tab Navigation

I am following http://www.youtube.co开发者_运维百科m/watch?v=gMu8XhxUBl8 example. Setting up the tabs is working fine. On each tab, I am using a cursor to get the data from SQLite and display it. where should I write that code ? In TabActivity ? In AFragmentTab ?

In your AFragmentTab Im sure this is where your work if any will take place.
