i want to publish an Android application with my google account using (inside the application) a google maps key of another google account. Is it possible?
Google maps key with different google play account
The Google Maps API key is tied to (documentation):
The certificate that you signed your release app with
The package of your app
So, yes, you can use one account to generate the API key and another to upload the app to the Play Store.
Thanks to your help, i found that android API must be enabled from backend. The second account was not set up properly, sorry for the loss of time! I share the link where enable google map api for android (because for iOS is not necessary) : Google maps api - android backend
