TYPE_ANNOUNCEMENT

val TYPE_ANNOUNCEMENT: Int = 16384(source)

Represents the event of an application making an announcement.

Note: This event carries no semantic meaning and is appropriate only in exceptional situations. Apps can generally achieve correct behavior for accessibility by accurately supplying the semantics of their UI. They should not need to specify what exactly is announced to users.

In general, only announce transitions that can't be handled by the following preferred alternatives:

Label your controls concisely and precisely. Don’t generate a confirmation message for simple actions like a button press.
For significant UI changes like window changes, use setTitle and setAccessibilityPaneTitle )}.
Use setAccessibilityLiveRegion to inform the user of changes to critical views within the user interface. These should still be used sparingly as they may generate announcements every time a View is updated.
