ShortcutBadger is an Android notification badge library and UI component designed to display numeric unread counts on application shortcuts. It functions as a cross-launcher badge manager to ensure notification consistency across different device manufacturers.
The library provides compatibility for various Android launchers, including those from Samsung, LG, Sony, and HTC. It implements this by mapping generic badge requests to manufacturer-specific internal APIs and utilizing dynamic vendor detection.
The project covers mobile notification management and system-level badge updates to reflect unread message counts on the home screen.
