Hi Tobias
I don't know enough about your specific problem, but I can only tell you
that the solution that I documented further up is in use in my production
applications without problem. The main difference I guess is that I do all
loader stuff inside the fragments (i.e. the initloader code is triggered
typically from MyFragment.onCreate()).
maybe you provide a few more details which would make it easier to help.
cheers
