can I change version code from apk?

Question

I build an app for android and I already export it to apk, can I change its version code if it's already exported? How can I do that?

I lost the backup code and I only have the update one and need to get back at first one, the only thing I can do is to increase version code from the apk backup and then my app will upgrade (while actually downgrade) automatically

Answer 1

You need to open apktool.yml from there you can modify the version code
