Android Question Changing app signature in Google Store

[Zeev Goldstein]

hi,

i have an old app in google play store
it is of course signed (with the old style signature)

now i have a new app and it had to be signed with the new style (RSA)

i see that B4A manages the signature as a central common recourse so if i set the new one it also applies to the old one

my question is - can i change the old app's signature to the new one and still it will be the same app as far as my users see?
so they will keep on getting updates etc?

or should i change the signature each time per each app ?

thank you

What happens when you try uploading a new version to the store?

Google information:

Use Play App Signing - Play Console Help

i don't dare to upload as i can't afford any issue with live users
it is a live application with many active users so if anything happens and the app will be for some reason handled as another or new one they will not get updates (if i am right)
that is why i have asked - to prevent such issue

Much more probable that you won't be able to change it, than easily break.

still, i don't dare playing with live app
i'll try to remember to change keys every time i touch it
at least until i get a certain answer

thank you

You don't have to release it. Just upload it to a production track. You can then delete the track. This will NOT affect your already released app in ANY way.

Still, I'm not playing with fire...

I need to know for 100%

Thanks

OK...Did you take a look at the link. It is possible to change the app signing key if you need to.

I will look at it tomorrow

Thanks
