How to remotely install an app on Android and check if it's up to date?

Question

Android

It is necessary to install the application on android tablets in an isolated environment (vpn 3g network), there is no access to google services and the Internet. There are a lot of tablets, about 1000 pieces, all geographically separated. It would also be nice to update the application and track the relevance of the version from clients (Android tablets).

Answer 1

Google has business accounts that allow you to manage permissions, policies, and apps on connected devices. Such a variant of a domain for tablets and phones, perhaps it will suit you.
The only limitation is that it only allows you to install apps from Google Play. You won't be able to centrally install your apk.

Answer 2

It was necessary to take care of the update in advance.
For example, at least install a remote control application ... not God knows what, but at least some kind of universal solution. If you have a developer, you could write a very simple silent remote install application, it's really easy.
If you have a remote chat on your phone - send everyone an appropriate message with instructions (make it so that it is enough to click once on the link in the message and confirm the permission once), but if you did not have permission to install from third-party places enabled, then this will your life is even worse.
If users have a non-personal google app account set up and you have access to them (for example, you know login passwords and two-factor authentication by code is not enabled), then you can manually (or write a clicker application) sequentially log in to each account on a desktop browser on play.google.com and delete add apps if it's in the google store.
