Sorry Guys. I have solved this Issue long ago. I did a lot of changes. So I can't figure out which one does the trick.

I have changed the id as suggested by Jared Burrows.
Removed my support library and cleaned my project and Re added it.
Go to File -> Invalidate Caches/Restart.

If you are using new androidximplementations, when typing Toolbar, the Studio will autocomplete it to android.support.v7.widget.Toolbar, but you should use androidx.appcompat.widget.Toolbarinstead, otherwise you will get this error.

I know this is an old question, but I recently ran into this same issue. It ended up being a Proguard problem (when I set minifyEnabledto falseit stopped happening.)

To stop it, with proguard enabled, I added the following to my proguard rules file, thanks to a solution I found elsewhere (after discovering that the problem was proguard)
