No, you will not need to resubmit your app if it was previously submitted and published in APK format. You may continue publishing new apps and updates to existing apps using the APK format. In order to utilize App Bundles, developers would need to plan future submissions using the new format (*.aab), however, there will be no changes in the way developers currently submit apps to Appstore.
Update as of October 5, 2023:
We are pleased to announce that developers opting for App Bundles on the Amazon Appstore are now able to optimize their app download sizes for all supported Amazon devices, including Fire tablets, Fire TV and Windows 11.
Based on their device configuration, customers will receive an optimized app tailored to their specific device configuration. The smaller app sizes may address storage capacity limitations on your customers’ devices. Additionally, you will be able to test App Bundles using the Live-App Testing feature, before publishing your app on the Amazon Appstore.
As always, we are working diligently to add more features to delight customers.

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.
