Android Studio not showing modules in project structure

Question

I am using Android studio and I want to add module to my project like \"action bar Sherlock\" or jar files, but when I opened the project structure there is no module or lib

Answer 1

I had the same problem, after switching to a branch that did not have my module, then switching back.

Clean Project -> Rebuild Project did not work for me.

But File -> Invalidate caches/restart did work.
