How to change SHA1 and SHA-256 of a project?

Question

android studio

Can I somehow change SHA1 and SHA-256 in the project? The problem is that my project, that is, the source code was purchased, and earlier they used firebase in it, and when I connected confirmation by phone number, I get such an error, although it works fine in a separate project!

Answer 1

You need to register in firebase, register your application there, add the hashes of your certificates, download google-services.json and put it in the app directory in the project.
