Accessibility Live Region

An Android accessibility attribute that tells TalkBack to automatically announce changes to a view's content, without requiring the user to move focus to it. Developers set it on a view to make dynamic updates such as error messages, status banners, or count-down timers audible to blind users. If a developer omits or mis-configures accessibilityLiveRegion, dynamic visual changes go unannounced — a common cause of mobile accessibility failures involving notifications, progress indicators, and auto-updating panels.
