Android Studio has introduced a new paradigm in project management, specifically with dependency management. With Eclipse, dependencies had to be manually added to the project. To update these dependencies, first the latest version would have to be downloaded then imported into Eclipse. And if that wasn't enough, this process was exacerbated by the fact that checking for updates on a dozen or so dependency meant keeping up with the project to make sure they would be no issues once the dependency was updated. Enter Gradle, the new Android build system introduced along with Android Studio. The process of adding and keeping up with dependencies has been greatly simplified.
