Modern Android notifications
summary
Notification channels are mandatory on API 26 and should be grouped by user-facing category, not by internal importance; Android P adds broadcasts to detect channel changes so apps can back up or sync settings. MessagingStyle gains a Person class on API 28 with setIcon and setData for images/stickers and supports setChoices for Smart Reply. Avoid using one channel, auto-canceling message threads, or empty names. Digital Wellbeing counts new and visible updates and DND honors notification categories and person URIs to allow exceptions.
