title: Android Studio: How to import java class from outside the project?
body: <p>I'm working on an android game that requires a server. We've set up a git in which there are three folders: Client, Server and Shared:</p>
  
  <p>Client contains the Android-Studio project.
  Server contains an Eclipse project which is our server and database.
  Shared contains java classes that I would like to use in both the Eclipse and Android-Studio project.</p>
  
  <p>In Eclipse I successfully loaded the files from Shared by importing them as "file system". (It created a package and everything works great)
  In Android-Studio, I can't find a solution that doesn't require me to copy-paste the classes in the project. The aim here is to have those file at only one location as they're susceptible to change but must me identical in both the projects... So those solutions don't fit my needs.</p>
  
  <p>I'm looking for something like a way to link files from outside the project. (I managed to link libraries from inside the project already but not from outside)</p>
