has-valid-accessibility-live-region

On android devices, when components dynamically change, we want TalkBack to alert the end user. This is made possible by the accessibilityLiveRegion property. It can be set to the following values:

  • "none": Accessibility services should not announce changes to this view.
  • "polite": Accessibility services should announce changes to this view.
  • "assertive": Accessibility services should interrupt ongoing speech to immediately announce changes to this view.
