The History of Notifications Every Developer Should Know
summary
A timeline of Android notification APIs from Ice Cream Sandwich through Oreo, noting actions and styles in Android 4.1, Material layout and heads‑up in Lollipop, bundled notifications and direct reply by API 24, and notification channels introduced in API 26. Concrete migration guidance: required fields (title, text, small icon, id), small icon must be white, branch logic by API level, use services or job schedulers to fetch images, create notification channels programmatically, and test on the oldest and newest supported Android and on Nexus devices for OEM quirks.
