Which signature is used by AppCenter Distribute for AAB distributed to Groups?

[fabiendem]

Hi,

Could you please clarify the following?

At https://learn.microsoft.com/en-us/appcenter/distribution/uploading#android

It says

➡️

When you distribute Android Application Bundle (AAB), App Center generates a universal APK, signs it with a generated signing key, and distributes it to a device.

It's not clear to me which signing key is used.

If I am already distributing APKs signed with my own key, and switch to AAB, won't there be a signing key incompatibility if I am not controlling the signature to generate the APKs from the AAB file?

Thank you

@fabiendem, thanks for getting in touch!

This query doesn't pertain to appcenter cli, so I recommend contacting our support team for assistance. They will be able to help you shortly.

Hey, indeed my bad. Answers from Support are sometimes a bit too simplistic and follow the script, so I wanted to reach out to the devs. I'm happy to close this, though. I understand. Let me know if https://github.com/microsoft/appcenter-sdk-android is worth a try, I don't intend to spam.

@fabiendem , thank you for understanding! There's no need to duplicate your post in the SDK repo 🙂 I already reached out to the appropriate dev team, and will get back to you in this thread if there is any valuable information!

@fabiendem , I discussed it with the team. All I can share is that we are using apksigner on our end. Hope it helps. If it doesn't, please reach out to the support team and they we help with any issues you are facing with apk/aab signing.
