How to change SHA1 in a project?

Question

Java

I want to put my first app on google play, but I get an error
The Android App Bundle is signed with the wrong key. Please select the correct key and try again. The App Bundle must be signed with a certificate with a SHA1:
XXX fingerprint.
However, for the downloaded App Bundle, a certificate with a SHA1:
YYY fingerprint is used.
I broke my head, but I don’t understand how to change this SHA1 in the project

Answer 1

SHA1 in this case is an easy way to understand whether the key is right or not. You must always sign the application with the same key, so its fingerprint will be the same. "Change SHA1 in the project" is a meaningless question. You can change the key, and in this case you need the key that you originally signed with.
