Android O: How to Use Notification Channels

Google has launched the first developer preview of the next Android version, currently code-named Android O (Oreo maybe?).

What Are Notification Channels?

Notification channels enable us app developers to group our notifications into groups—channels—with the user having the ability to modify notification settings for the entire channel at once. For example, for each channel, users can completely block all notifications, override the importance level, or allow a notification badge to be shown. This new feature helps in greatly improving the user experience of an app.
