…but, instead of writing as alias “MyKey” as shown in the code, I put one of my own; this was because I had followed the guide without understanding what I was doing.
ExampleKey.keystore is the file key name, it must be written as KeyStore in Distribution Signing section MyKey is the alias name, it must be written as Key Alias in Distribution Signing section
Both names can be changed at will as long as they fit in the quoted code, this is the point.
I know it may seem silly to explain something that is already explained in both the guide and the section Distribution Signing but I think it can be of help to other beginners like me.
I took months to understand it, I hope others take less
