What is an AAR file?

Android Archive

AAR files are the gateway to reusing code and resources across multiple applications. Packaging libraries into a single file format, AARs contain compiled code, resources, and a manifest that outlines dependencies.

By importing an AAR package into an Android Studio project using the “New Module” wizard - with the option of “Import.JAR/.AAR Package” - developers can incorporate it as a dependency just like an Android Library module. Using this method they save time and effort within development by availing reusable components.

AAR files can be created using the Android Gradle Plugin and are typically stored in an Android app project's "libs" directory. They can be imported into an Android Studio project using the "New Module" wizard and selecting the "Import .JAR/.AAR Package" option.
