This question can also be extended if necessary jar file can be found in global library, how can you configure it into your current project.

Process like these: "project structure"-->"modules"-->"click your current project pane at right"-->"dependencies"-->"click little add(+) button"-->"library"-->"select the library you want".

if you are using maven and you can also configure dependency in your pom.xml, but it your chosen version is not like the global library, you will waste memory on storing another version of the same jar file. so i suggest use the first step.

A better way in long run is to integrate Gradle in your project environment  Its a build tool for Java  and now being used a lot in the android development space   You will need to make a  gradle file and list your library dependencies  Then  all you would need to do is import the project in IntelliJ using Gradle   Cheers

I ve used this process to attach a 3rd party Jar to an Android project in IDEA    Copy the Jar to your libs  directory  Open Project Settings  Ctrl Alt Shift S  Under the Project Settings panel on the left  choose Modules On the larger right pane  choose the Dependencies tab  Press the Add    button on the far right of the screen  if you have a smaller screen like me  you may have to drag resize to the right in order to see it  From the dropdown of Add options  choose  Library   A  Choose Libraries  dialog will appear  Press  New Library     Choose a suitable title for the library Press  Attach Classes     Choose the Jar from your libs  directory  and press OK to dismiss   The library should now be recognised

Easier procedure on latest versions    Copy jar to libs directory in the app  you can create the directory it if not there  Refresh project so libs show up in the structure  right click on project top level  refresh synchronize  Expand libs and right click on the jar Select  Add as Library    Done
