I just wonder what the actual working process of app bundle is. How does it work in devices in comparison with the APK file?

App bundles are publishing format, whereas APK (Android application Package) is the packaging format which eventually will be installed on device. Google uses app bundle to generate and serve optimized APKs for each user’s device configuration, so they download only the code and resources they need to run your app. Therefore, users can get smaller and more optimized downloads.

An apk is a full package for an Android application to be installed on an android device.
But an aab is a file that developers can upload to Google Play to support Dynamic Delivery.

Download size < 0.07 MB. But also Accurate, Ad-Free & Full-Free.

APK stands for Android App Package. An APK is basically a file that’s ready to be installed on a user’s device. APKs have all of the app’s files and code inside. You can think of it as a .zip file but with its own particular extension. Just as you can find compressed files with extensions in .rar or .zip, you can have .apk. AAB stands for Android Application Bundle. Just as APK is an extension, AAB files also have the extension .aab.
