Clickable span

This rule checks if links are displayed using a ClickableSpan before Android 8.0 (API level 26).

Accessibility services are not able to activate a ClickableSpan before Android 8.0. An exception to this rule is an URLSpan which does not contain a relative URI.

Solutions

• Use ViewCompat.enableAccessibleClickableSpanSupport(android.view.View) to make a ClickableSpan available to accessibility services as early as API level 19.
• Use a URLSpan with a matching IntentFilter to handle the click action, as an accessibility service may activate these hyperlinks through an intent broadcast.
