Question

android-studio 0 2 7 Fedora 18   Hello   I am trying to add the jtwitter jar to my project   First I tried doing the following   1  Drag the jtwitter jar into the root directory of my project explorer  see picture 2  File   project structure 3  Modules   yamba-yamba   dependencies 4  Click the plus sign   jars or directories   and navigate to jtwitter jar   click ok     When I import the jar file I get the following error   import winterwell jtwitter Twitter   Cannot resolve symbol winterwell Gradle  error  package winterwell jtwitter does not exist   I researched and found that android-studio has some issues and that you have to edit the build gradle file yourself   So I tried adding this to my build gradle file   dependencies       compile files  libs jtwitter jar       And got an error message  cannot resolve symbol dependencies  Another question  where would the libs folder be  Does it mean the External Libraries   Any help will be most helpfull

Android Studio 1 0 1 doesn t make it any clearer  but it does make it somehow easier  Here s what worked for me   1  Using explorer  create an  external libs  folder  any other name is fine  inside the  Project app src folder  where  Project  is the name of your project  2  Copy your jar file into this  external libs  folder  3  In Android Studio  go to File -  Project Structure -  Dependencies -  Add -  File Dependency and navigate to your jar file  which should be under  src external libs   3  Select your jar file and click  Ok   Now  check your build gradle  Module app  script  where you ll see the jar already added under  dependencies

If the code for your jar library is on GitHub then importing into Android Studio is easy with JitPack    Your will just need to add the repository to build gradle   allprojects   repositories       jcenter       maven   url  https   jitpack io           and then the library s GitHub repository as a dependency       dependencies                  compile  com github YourUsername LibraryRepo ReleaseTag      JitPack acts as a maven repository and can be used like Maven Central  The nice thing is that you don t have to upload the jar manually  Behind the scenes JitPack will check out the code from GitHub and compile it  Therefore it works only if the repo has a build file in it  build gradle    There is also a guide on how to prepare an Android project

Avoid redundancy  If you have your jars under  libs in your app build gradle by default you will have  dependencies       compile fileTree dir   libs   include      jar                that is enough to add all the jars you have under  libs  this is not necessary        compile files  libs activation jar         compile files  libs additional jar         compile files  libs mail jar

I also faced same obstacle but not able to find out solution from given answers  Might be it s happening due to project path which is having special characters  amp  space etc    So please try to add this line in your build gradle   compile files     app libs jtwitter jar     pass your  jar file name         Double dot  will find your root directory of your project
