Rotation support

Rotation support: Headless fragments
Detail Fragment: Provides a detailed view of a specific entry
This is going to be a issue.
In order to find out whether I'm on portrait or landscape I make use of views. Views configured by setContentView(); 

Parent activity# onCreate
isDualPane = findView( ... )    // There are NO views, because childrenActivity#Oncreate hasn't called setContentView(...) just yet.

In a parent activity, these views don't exists yet. So the result of isDualPane will always be false.
