I need to publish an app privately , where only those who have the address or release can do download and updates via appstore , you can control the application?
Can I at least automatically update an application without copying to the phone and installing over the old version?
There is a way for you to create a group of testers, where only they can receive the application, by invitation, see this example from google, to first test your apps in beta format.
In this officinal page google (ptbr) teaches you how to create a group of testers, just follow the guidelines of the page.
If you have questions, this page below has a step-by-step guide as well, but google's offical page is more than enough.
