Here’s why Google is phasing out APKs in favor of Android app bundles
Announced yesterday on Google’s Android Developer Blog, APKs or Android app packages will be phased out as a standard post format in favor of the new AABs. With this change, AABs will allow apps to be on average 15% smaller than a universal APK. Additionally, AABs improve security, feature delivery, and asset delivery to the end user, improving the overall application experience.
Google further explains that when it comes to switching to this format, “very little work is required to create an AAB instead of an APK”. It is mainly a matter of selecting a different option when creating an application via “Android Studio, Gradle, Bazel, Buck, Cocos Creator, Unity, Unreal Engine and other engines”.
While much of this might sound like gibberish to many, it’s a simple change that aims to improve the Google Play experience for everyone. Updates will be smaller and smoother, and developers should end up with more granular control over app delivery, a win-win across the board.
