With the NavigationDrawer and the recommended way to implement it according to google it should be with fragments. Which creates a lot of nesting which does not seem to be too supported. And kind of messes up the idea of having activities with fragments for supporting different layouts.
So I wonder what the best suggestion would be if you have have a layout, that on a phone will be a list on the whole display, and on tablet you will have a list on the left side and detailed information about the item clicked on the right side? Ses images attached as links. It would have felt more natural to have activities instead of Fragment A, different for each layout.
Fragment A is the fragment that your navigating to. Fragment B in both variants should be the same except for what's gonna happen when you click on an item. In the phone example the Fragment B should be an expandable list and on the tablet it should show the details in Fragment C.
