Java – How to add .jar files in Android Studio

I’ve moved from Eclipse to Android Studio for Android programming.
I’m having trouble importing .jar files in Android Studio.
I can’t seem to import any files from my jsoup package.

Error:(6, 17) error: package org.jsoup does not exist
Error:(7, 23) error: package org.jsoup.nodes does not exist

Add the following to the build gradle file in the dependencies section:

compile fileTree(dir: 'libs', include: '*.jar')

The above assumes that the library is located in the libs folder of the project.

Alternatively, you can add a dependency like this by telling Gradle a separate jar file:

compile files('libs/yourlibrary.jar')

After adding this line, you should sync your project again, and Android Studio should now allow you to import these classes from your library.

Update: The jsoup library is actually available in the mavenCentral repository. Therefore, a good way to include this dependency is:

 compile 'org.jsoup:jsoup:1.8.2'

Or just do it to always have the latest version:

 compile 'org.jsoup:jsoup:+'

Note: If you do, you need to add the mavenCentral repository to the build level:

 repositories {
     mavenCentral()
 }
