Have you seen about these changes?
An Android App Bundle is a new upload format that includes all your app’s compiled code and resources, but defers APK generation and signing to Google Play.
Google Play’s new app serving model, called Dynamic Delivery, then uses your 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. You no longer have to build, sign, and manage multiple APKs to support different devices, and users get smaller, more optimized downloads.
Additionally, you can add dynamic feature modules to your app project and include them in your app bundle. These modules contain features and assets that you can decide not to include when users first download and install your app. Using the Play Core Library, your app can later request to download those modules as dynamic feature APKs, and, through Dynamic Delivery, Google Play serves only the code and resources for that module to the device.
