A big change in Android version 8.0, O release is Notification Channels. This allows apps to break their notifications into categories and let users control each channel separately. For example, if you are a news app, you can create channels for each of the sections, and users can block notifications for topics that they do not want to follow.
Google Chrome is also implementing this feature on its Android app. On Chrome for Android, this will enable separate notification channels for websites. For example, you can have separate notification settings for separate websites. Along with this, there will be a “Browser” channel for Chrome’s notifications like downloads and media etc.
According to this design guide the objective is to:
Embrace notification channels fully to give users more fine grain control over which sorts of notifications they see from Chrome and how they appear. Let users choose which sites can send them notifications directly from system notification settings to avoid users blocking all site notifications when they only wish to block one site.
Each site now has their own channel, allowing user-customization of how notifications from different sites appear, and improving discoverability of the toggle to block or re-allow notifications from a specific site (previously only visible in Chrome site settings).
Here is an example:
From the way it looks, just like Android O, this will be a huge improvement for Chrome notifications as well!
