Earlier this year, Android App Bundle format was announced by Google as mandatory open-source format for new Google Play app submissions starting August 2021. Amazon Appstore is actively working to support the new format, which will provide benefits such as smaller app size downloads for customers and on-demand downloads for features and assets. These changes benefit customers by helping them download specific aspects of an app in real-time as needed.
For Amazon Appstore developers, in addition to the existing APK format, we are working to support the app bundles format across all types of submissions. We will share updates later this year on our progress to continue making app submission as simple and friction-less as possible for our developers.
