Android studio doesn t use Maven  it use Gradle  you can open your build gradle the route should be   app build gradle and add the Gradle dependency that shows on the repo   The build gradle has a dependencies section   dependencies         here add your dependency     The repo says that you need to add this dependency   compile  com foursquare foursquare-android-oauth 1 0 3    only add that line to your dependencies on buil gradle  save the file  and android will rebuild the project  that s all

A late answer  although I thought of giving an in-depth answer to this question  This method is suitable for Android Studio 1 0 0 and above   STEPS   First switch your folder structure from Android to Project        Now search for the libs folder inside app - build folder       Once you have pasted the  jar file inside libs folder  Right click on the jar file and at end click on Add as library  This will take care of adding     compile files  libs library name jar   in build gradle  You don t have to manually enter this in your build file       Now you can start using the library in your project

If the library you need is on GitHub then adding it to Android Studio is easy with JitPack   Step 1  Add the jitpack repository to build gradle   allprojects      repositories       jcenter       maven   url  https   jitpack io            Step 2  Add the GitHub repository as a dependency       dependencies                  compile  com github Username LibraryRepo ReleaseTag      JitPack acts as a maven repository and can be used much like Maven Central  The nice thing is that the maintainers don t have to upload the library  Behind the scenes JitPack will check out the code from GitHub and compile it  Therefore for this to work there needs to be a working build file in the git repository   There is also a guide on how to publish an Android library

There are two simplest ways if one does not work please try the other one    Add dependency of the library inside dependency inside build gradle file of the library you are using   and paste your library in External Libraries    OR   Just Go to your libs folder inside app folder and paste all your  jar e g Library files there  Now the trick here is that now go inside settings gradle file now add this line include   app libs  after include   app  it will definitely  work
