Adding external library in Android studio

Try this:

File > Project Structure > Dependencies Tab > Add module dependency (scope = compile)

Where the module dependency is the project library Android folder.


Try one of these approaches:

Approach 1)

1- Choose project view

2- Copy your JAR file in app -> lib folder

3- Right click on your JAR file and choose add as library

enter image description here

3- Browse your JAR File

enter image description here

4- Finish

5- File -> Project Structure -> Dependencies

For first two approaches, you need a JAR file. You can search http://search.maven.org/ to find JAR files that are related to Android. For example, this is the search result for jdom in this link

Search result for jdom


Approach 3) Android is using http://jcenter.bintray.com/ as remote library. For example, this is the search result for jdom in the link.

jcenter jdom

To add a library in this approach, please follow these steps:

1- File -> Project Structure -> Dependencies

2- Click on + button and choose library dependency

3- find your library and select it, then click OK.
