Neither of the links referenced here use apksigner to sign an aab

https://github.com/Android-for-Python/Android-for-Python-Users#release-builds

Both use keytool

Hey everyone, 

with that command i reach my app signed:

jarsigner -verbose -sigalg SHA256withRSA -digestalg SHA-256 -keystore app.keystore app.aab appAlias

i used it and fixed, i think

now i will see if all works at playstore

Let's see: I was wanting to update my app on the playstore, however when I signed the app it displayed that error shown there, so I put the parameter as suggested --min-sdk-version 30 on the same line of apksigner sign... at the end, and that worked here.
