This is the easiest method to import your existing project from eclipse to android studio. Since Android Studio project structure is different from Eclipse, while importing using Android Studio Importer, it automatically make some changes to your Eclipse Project which are required to run your program in Android Studio. Required changes includes replacing existing JAR files and libraries with Gradle dependencies. It also replaces your source libraries and binary libraries with Maven dependencies, and due to that you don’t need to maintain these manually.

2. Export From Eclipse IDE :
