AAB File Sharing Best Practices

Master Android App Bundle (AAB) sharing for modern Android development. Secure distribution of publish-ready app bundles.


Sharing Android App Bundles (AAB) Securely


Since 2021, Google has required the Android App Bundle (AAB) format for all new apps on the Play Store. Unlike APKs, AABs are not directly installable on devices, but they are crucial for sharing between development teams and publishers.


Why AAB Sharing is Different


  • **AAB**: A publishing format that includes all your app's compiled code and resources but defers APK generation and signing to Google Play.
  • **Security Stake**: AABs contain your entire source logic optimized for distribution. If an AAB leaks, your entire app architecture is exposed.

    • How to Share AABs Securely


  • **Internal App Sharing**: Use the Google Play Console's internal sharing for small test groups.
  • **Third-Party Distribution**: For sharing with third-party publishers or external QA teams, use a secure, temporary link.

    • The 24-Hour Vaporization Rule

    Always set an expiry on shared build artifacts. If you share an AAB via a permanent cloud link, you might forget it. A compromised account years from now could lead to data leaks of old, vulnerable source codes.


    Using **VaporLink**, the AAB exists only long enough for your recipient to download it, then it vanishes. This minimizes your digital footprint and maximizes security.
