Notification Channels
Group notifications by importance.
Notification Channels
Since Android 8.0 (API 26), every notification must belong to a channel. Channels group related notifications and let users control them individually in system Settings.
Why Channels Exist
Channels give users fine-grained control. Instead of a single on/off switch for the whole app, users can mute "Promotions" while keeping "Messages" loud. This reduces notification fatigue.
