Accessibility Talk, Button. Double-tap to activate.
summary
Android accessibility is concrete: label clickable views or mark them not important for accessibility, make tap targets 48dp tap targets, and check color with contrast ratio 1–21 (under 3 is inaccessible, 3–4.5 only for large text, 4.5+ recommended). Test with TalkBack gestures (two‑finger scroll, left‑right skip, down‑up to last item), use Accessibility Scanner and contrast-ratio.com, hide background views with importantForAccessibility, and avoid default rating bars (built a GitHub demo and implements a custom submit flow so ratings don’t misfire).
