Application has stopped unexpectedly. (Because of tabView)

Question

I'm trying to do an app which use Tabs. I follow this tuto: http://mobileorchard.com/android-app-development-tabbed-activities/

I succeeded to do a tab using one activity, but my problem is when I try to do the part using some activities.

I begin with android, could you help me ? Could you say me if the way I use to do it is good ? (sorry for my english ^^)

Before the app stopped unexpectedly I have the error:

Answer 1
