Sign apk with keystore on another computer

Question

I want another person to sign my apk and upload to Google Play. I saved the keystore, so just using the same keystore on another computer (the same alias?), Can another person log in to the Google game? He says that he received a signature error.

Answer 1

If this is the same key (note the key , not keystore ), since you may have different key stores in fact, but only one key is used for signing) on ​​both computers, and the same key is used to enter the application . Then yes, it doesn’t matter who really signed the application. From a technical point of view, it is important that the application is signed with the same key. Once this is done, you or another person can easily upgrade the version on Google Play. So really. it is most reasonable to use one key not the whole keystore .
