The Android App Bundle is Android's new, official publishing format that offers a more efficient way to build and release your app. The Android App Bundle lets you more easily deliver a great experience in a smaller app size, which can improve install success and reduce uninstalls. It's easy to switch. You don't need to refactor your code to start benefiting from a smaller app. And once you've switched, you'll benefit from modular app development and customizable feature delivery.
Available in Android Studio 3.2 or later, Unity 2018.3 & 2017.4.17, and Cocos Creator 2.0.9 or later.
