How Do Push Notifications Work on Android

The Android system looks at the message to determine which app it’s for, and starts that app. The app must have registered with Android to use GCM, and it must have the relevant permission. When the app starts, it might create a notification straight away with the data from the message.

What happens when you turn on push notifications?

It is a way for an app to send information to your phone (via a badge, alert, or pop up message) even when the app isn’t in use. For example, if you have a sports app with push notifications enabled, that app can send you the latest score of your favorite team even if the app isn’t running.

What is the difference between a push notification and a text message?

In short, an SMS text message allows users to send text messages up to 160 characters in length via a text client. … In contrast, a push notification is a brief message or alert that is “pushed” through an application to recipients who have downloaded that application.
