Push notifications let your application notify a user of new messages or events even when the user is not actively using your application. On Android devices, when a device receives a push notification, your application’s icon and a message appear in the status bar.
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. The notification will send you a message, and when you touch it, it will direct you back to the app for more information.
But ultimately, YOU, the user, are in charge of what notifications you do, or don’t, receive. So let’s review how you can control these alerts.
