Google explains it here:
Apps already published in the Play Store can continue to use the v1 scheme, created with
keytool, because updates aren't possible if the signature changes. But new apps should use the
v2 scheme which is done with apksigner.
I got a little lost in that web page when determining what the variables should be in the
terminal command. Some guidance on that would be helpful. I do remember when I created the
signature for an app a few months ago, I got a warning that I was using v1 and I should
consider using v2 instead, but Google did not reject the app with the v1 signature.
