Building Accessible Apps with Jetpack Compose
summary
Covers concrete Compose practices: use minimum 48dp touch target and the MinimumInteractiveComponentSize modifier; size text in sp and test up to 200% font scale with preview phoneScale; expose state and actions via the Semantics modifier (use mergeDescendants for icons+labels, set contentDescription or null appropriately); handle TalkBack gestures (single tap moves focus, double tap activates) and add customActions for swipe-to-delete; mark changing UI with LiveRegion polite/assertive; test with Accessibility Scanner and Play Store pre-launch reports.
