Question

http://developer.android.com/tools/publishing/app-signing.html

I have a keystore that I already have an alias and password for.

I have released applications using this keystore.

I have now given ownership of one of these applications to someone else, and so to update that application they need to use my keystore. However I don’t want them to use my alias or password.

Is it possible to create a new alias and password for the same keystore

and just as importantly

will Google Play allow an APK signed with the new alias to be used as an update for that already published app?

If so what is the command, or a good help link please?

Answer 1

Ok I got it, thanks @Rossco for the initial boost.

First I copied my keystore to a new file

ctrl+c ctrl+v

Then I changed the password on the keystore:

keytool -storepasswd -keystore my.keystore

Then I changed the name of the alias in the keystore

keytool -changealias -keystore my.keystore -alias "old_alias" -destalias "new_alias"

Then I changed the password for the new alias:

keytool -keypasswd -keystore my.keystore -alias new_alias -keypass oldAliasPassword -new newAliasPassword

And yes I’ve just tested it and uploaded a new version of the app with the new keystore alias

Thanks!
