Yes, I already thought about that, but I wanted to be sure not overseeing a "better" solution.
Your class is a great help to provide action bar handling for devices not really supporting it.
Maybe I should put a wish on Erel's todo-list for a better build-in support of the action bar (like the menu) because as this is a really key feature of android 3.0 and above I think a direct support is necessary instead of implementing all those features manually with an own class.
