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 June 3, 2022:
The Android App Bundles format was announced by Google as a mandatory open-source format for new Google Play app submissions beginning August 2021. We are pleased to announce that developers can now submit apps using the the App Bundles format in addition to the existing APK format. Soon, we will support additional App Bundle features, which will enable smaller app size downloads and on-demand downloads for features and assets.
Our team is working diligently to continue to make app submission as simple and frictionless as possible for developers.

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.
