Traditionally, APKS have been used to provide Android applications with its updated new packages. These files have cataloged variants of the application with its corresponding media types. For example, icons or sounds. However, to authorize the publisher, it adds a document to the details of the Android app and accreditations a signature code. Google introduced a new enhancement to the packaging format in May 2018. It worked due to the discrepancies in APK and is known as Android App Bundles (AABS). The purpose of the App Bundles was very much like APKs except for its implementation discrepancies.
