Description from the creator

In this video series we will learn everything about notifications in Android.
In part 1 we will start by creating notification channels (Categories) which are necessary since Android Oreo (API level 26) to be able to show any notifications. These channels should be created as soon as we start our app, so we will do it in the onCreate method of a class that extends Application.
When we create these channels, we have to pass an ID, a name and an importance level. Additionally we can customize the channel further, like enabling the LED, activating vibration or changing the sound, but the user has ultimate control over the channel's behavior.
When our NotificationChannel objects are created, we pass them to the NotificationManager's createNotificationChannel method.
When we then want to show a notification, we create it with the NotificationCompat.Builder, where we can set a title, a message, an icon, a priority level, a category and many more customization options, and then we pass this
Notification object to the NotificationManagerCompat's notify method, where we also have to pass an ID which we can later use to update or cancel this particular notification.
