Firebase Cloud Messaging alternative for corporate network?

Question

Android

Good afternoon.

Do you need to implement push notifications for applications in a corporate network (without the Internet), and not eat a lot of battery?
Do I understand correctly that this is not possible?

Answer 1

It all depends on how much you can sacrifice the urgency of delivery. For example, you can periodically knock on the server, present a certain subscriber token, and ask if there is anything for you. And the server will give what has accumulated. Such a periodic server poll must be done using the Worker so that Doz-mode does not interfere. Well, the less often you poll the server, the less battery will be consumed.
