Sign apk with keystore in different computer

Question

I want another person to sign my apk and make uploads to Google Play. I have stored the keystore, so, just using the same keystore in the other computer (same alias?), will the other person be able to upload to google play? He's saying that he get an error of signature.

Answer 1

If this is the same key (note, key, not keystore used matters as you can have different keystores really, but only single key is used for signing) on both computers and the same key is used to sign the app, then yes, it will make no difference who really signed the app. From technical perspective it matters that app is signed with the same key. Once this is done you or the other person will be able to issue update to Google Play with no problems. So in fact. it's wiser to just share single key not whole keystore.
