I just started working on a new library for action bars.
I would love to have support for
ActionBarSherlock but this is currently not possible (Activities have to extend FragmentActivity and some other problems).
So I decided to convert this
Action Bar implementation to a B4A Library. The pain with all these Android Library projects is that they make use of the Android resource system with all the XML files. This can't be packed into a .jar file and has to be converted into program code and this is an awful work.
The advantage of ActionBarSherlock would be that it uses the native ActionBar implementation on Android >= 3.0. But I think the solution from Johan Nilson is better than nothing.
Perhaps Erel could build Android Library support into B4A in the future so that we can use them directly from a wrapper class. But this will make the handling of libraries much more complex.
