I want to install a single-purpose app on a thousand of devices of the same model.
The need :
- The app shall not be public therefore accessible to anyone
- The app shall be installed on my 1.000 devices. Note that the devices are the same model (let's say nexus 10) but I do not want to grant access to all nexus 10 around the world
- It shall be as easy as possible. I can imagine for example logging in these 1000 device with a single account and then limiting ditribution to that account, but it's quite long and might as well not be possible (limitation to the number of devices an account can have)
- The app shall be updatable on all devices simultaneously
- The number of devices might grow to 2.000 or even OVER 9.000
