That’s what you should see when your notification is displayed. The notification id can be any number, it’s used only if you need to interact with the notification later. The next step is simply calling notificationManager to show the notification.

If you want to learn how to customize you notification you can take a look at the Android Documentation. The CHANNEL_ID parameter has to have the same id we used earlier to create the channel. Then we call NotificationCompat.Builder to define how the notification will look like. Now that we have created a channel, we can proceed to creating the notification.įirst we start by creating a PendingIntent, that’s the intent that will be called when the notification is clicked, here we’ll simply start an activity. You should register your channels as early as possible, preferably when Application.onCreate is called.Ĭhannels are immutable, if you need to change some channel configuration you’ll either have to delete the app or change the channel’s id. There’s no problem in calling createNotificationChannel multiple times with the same channel, Android will ignore it if there’s an existing channel with the same id. Up until Android Nought (25), there’s no need to create notification channels, that’s why there’s a guard cause at the beginning of the method. Finally we call notificationManager.createNotificationChannel to register the channel. We also change the lockscreenVisibility to Notification.VISIBILITY_PUBLIC to tell Android that the notification can be shown on the lock screen. It’s advised to use NotificationManager.IMPORTANCE_HIGH for increasing the chances of the notification appearing as a heads up notification.
Then we create a NotificationChannel that takes the channel’s id, name and importance as arguments. That’s the interface used for dealing with notifications on Android. The first thing we need to do before creating the notification is creating the channel to display it.įirst we retrieve the NotificationManager from NotificationManagerCompat. Let’s start by creating a simple notification that’ll be used later to show an Activity on the look screen.

By default Android will show the same notification it shows when the device is unlocked but in some cases, such as a phone call, you might want to display a full screen activity.
