What is an AAR file?

AAR files mostly belong to Android Studio by Google & JetBrains. An AAR file is a web service deployment package used by Axis web service engine. This file contains all servlets, pages, and scripts required to implement a web service. It is created by Axis' Service Archive Generator plugin which is compatible with Java and C++ integrated development environments such as Eclipse. Another type of AAR file is a ZIP-compressed application library created by Android Studio integrated development environment. An AAR library contains source code (Java classes and methods, C/C++ libraries), static resources, and executables required to build an app. Groove Coaster uses various data saved in an AAR file.

How to open an AAR file
