Dynamic Delivery
Another great feature of App Bundles is dynamic delivery, which helps your apps get even smaller!
The idea is that you can split your apps by feature modules in such a way that parts of your app that are not as popular can be downloaded on-demand, only when the user needs them and not as part of your main APK. It’s the same idea as that of downloading resources, but with code instead. Pretty cool! :]
This feature of App Bundles is currently in Beta, so to be used in production you have to opt-in.
Backwards Compatibility
Devices on Android 4.4 (API level 19) and lower do not support split APKs, which are the foundation of delivering multiple APK files to devices. Google Play serves a single APK version that includes resources for all languages that your app supports on those Android versions. For backwards compatibility, you don’t have to take any additional steps, since Google Play takes care of everything for you.
Where to Go From Here?
Now that you’ve gotten started with App Bundles, you should try using App Bundles with your own apps and publish an Internal track on the Google Play Store. You can also test your App Bundles locally using Bundletool.
