The accessibility scanner offers you recommendations on every highlighted merchandise, these recommendations are primarily divided into few areas, reminiscent of:

1. Low distinction

The Accessibility Scanner suggests enhancements to paint distinction ratios to make your app extra accessible to customers with visible impairments.

Identifies textual content or photographs with a distinction ratio of lower than 3.0 between the textual content shade and the background shade (for non-gaps). TextViews) or between the foreground and background shade (for ImageViews).

  • textual content scaling
    Identifies potential points with font measurement and structure specs when designing a consumer interface that will trigger textual content to be cropped, minimize off, or hidden.

4. content material tagging

Many consumer interface controls depend on visible cues to point their that means and use. A visually impaired consumer might have problem seeing these indicators. To make the consumer management interface extra accessible, use content material tags. Content material tags don’t seem on the display screen, however might be accessed by visually impaired customers by way of accessibility companies reminiscent of TalkBack or different display screen readers.

With the scanner you possibly can search for the next content material tagging alternatives, they may very well be like:

  • Lacking merchandise label
    identifies Views {that a} display screen reader may give attention to and which have an empty spoken description, both for the View or related Views in its sub-hierarchy.
  • Merchandise tagged with kind or standing

After getting all of the concepts, make sure to flip it off as nicely. navigate to Settings > Accessibility and set up Accessibility Scanner Off.

Simply to sum this up, accessibility must be addressed holistically: the Accessibility Scanner, for instance, will inform you for those who’re lacking a tag, however it will possibly’t inform if that tag is sensible.

Usually, the Accessibility Scanner can’t decide whether or not your consumer interface conveys semantic info merely and clearly. Moreover, Accessibility Scanner can’t report how nicely an app helps a number of modes of interplay (contact vs. speech), or whether or not customers can efficiently full your app’s most typical use instances.
