Content Description

A text attribute on Android UI elements that provides an accessible label for screen readers like TalkBack. Content descriptions serve the same purpose as alt text on web images — they convey the meaning or function of visual elements to users who cannot see them. For interactive elements like image-based buttons, a content description should describe the action the element performs (e.g., "Search" or "Navigate up") rather than its visual appearance. Missing or uninformative content descriptions are among the most common accessibility barriers in Android apps.
