How to correctly update information from the server for Android?

Question

Android

Hey! Let's say there is an application for drivers. It is necessary to notify them about new routes somehow.
I understand correctly that the application must constantly send requests to the server and return data about new routes?
That is, there is a constant waste of traffic!?

Answer 1

no, of course, you can use gcm or fcm or something else, it's a very bad idea to hit the server all the time)
