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.
App Bundles will be completely optional, and developers will be able to continue submitting apps using existing APK format.
There are no changes to the app submission process. For both app formats (APK or bundle), developers will continue to submit apps in the same way as before.
No, you will not need to resubmit your app if it was submitted and published in APK format earlier. You can continue publishing new apps and updates to existing apps using APK format. In order to utilize app bundles, developers would need to plan future submissions using the bundles format (*.aab), however, there will be no changes in the way developers currently submit apps to Appstore.
We will support upload of apps in App Bundle format. We have a roadmap to enable customer experience benefits incrementally over time. We will share our roadmap and more details closer to rollout.
No, Amazon Appstore does not require you to share your app signing key to submit App Bundles. You will continue to sign App Bundles similar to the way that you sign APKs and submit today.
