i've been struggling to make my navigation drawer appear below the action bar. I know it may not be according to design guidelines. I have visited several other threads about the subject (example: Navigation drawer below Actionbar), which didn't solve my problem.
After lots and lots of tinkering, i didn't get further. Please help with this problem.
