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
Go to File->Project Structure-> Project Settings -> Modules.
Click on the green colored + and add new module. select Application module and set the content root to your project module.
Click next and then finish.

Here's what I did to solve this problem
Update 19 March 2019
A new experience someone has just faced recently even though he/she did add a library module in app module, and include in Setting gradle as described below. One more thing worth trying is to make sure your app module and your library module have the same compileSdkVersion (which is in each its gradle)!
Please follow this link for more details.

Original answer
Sometimes you use import module function, then the module does appear in Project mode but not in Android mode
So the thing works for me is to go to Setting gradle, add my module manually, and sync a gradle again:
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.
Do right mouse click on your project, then select 'Open Module Settings' - then you can add modules to your project..
