Hi @Shreyaa,

Are you able to make a guide on how to change the target sdk for an AAB and then sign it? I think all you have to do is extract the base APK, use ApkTool to change the target sdk, build the base APK, sign the base APK (I think), add the base APK back to the AAB, then resign the AAB. It seems like an exhaustive process, but it isn’t.

Sincerely,

– Nathan

I added Part 2 on how to sign AABs to my video tutorial.
It takes less than 1 minute to insert large files into the assets and sign the AAB.
