How to Display Navigation Drawer in all activities?

Question

I have a Navigation Drawer which should appear in all my activities.

I saw many questions similar to this & found a solution like Extending the Main

Answer 1

You omitted the @Override from your derived class onCreate.

UPDATE: I'm not sure what the effects are of calling setContentView twice but that could be the problem. Separate out the code that sets up the drawer, and call that from both of the onCreate methods.
