[Updated] Amazon Appstore to support Android App Bundle


Update as of March 29, 2024:

For App Bundles containing asset packs, Amazon Appstore will only support install-time asset packs going forward. On-demand and conditional delivery modules are merged into the optimized APK, irrespective of "fusing" attribute in your app manifest files. Convert your asset packs into install-time assets to avoid disruptions during your next app submission.

Review the technical documentation to learn more.


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.

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.

Previously published on July 16, 2021:

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.


Update as of March 29, 2024

There are no changes to the app submission process. For both app formats (APK or App Bundles), developers will continue to submit apps in the same way as before. App Bundles will be completely optional, and developers will be able to continue submitting apps using the existing APK format. There are no changes in terms of size restriction for app files to be submitted (<2.5 GB check will be in place for aggregate size of all App Bundles).

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.

In its current format, only Appstore signed apps will be able to upload App Bundles. However, existing users who self-sign apps are not expected to switch over, and we are working on supporting the self-signing use-case as well.  

Currently, Appstore doesn’t support App Bundles submitted via submission API or apps using their own app signature. We currently support install-time modules, on-demand modules, conditional modules and install-time asset packs. Refer to technical documentation for more details. Appstore is actively working on adding support for these features, and more.
