Android VPAT journey

Slack shares lessons from their 2024 Android VPAT accessibility audit, detailing how they resolved key issues found after a major UI change.

• •Error messages were made accessible by updating OutlinedTextField and SKBanner to immediately announce errors to TalkBack users
• •Missing headings in list views like the Preferences page were identified and fixed to support screen reader navigation
• •The workspace switcher gained an Edit mode with custom TalkBack actions (Move up/down) to replace inaccessible drag-and-drop gestures
• •Incorrect list item counts caused by decorative SKDivider elements were fixed via a new SKListAccessibilityDelegate
• •Error states previously indicated by red color alone were updated to include additional visual cues for color-blind users
