public final class GestureDescription
extends Object

java.lang.Object
↳	android.accessibilityservice.GestureDescription

Accessibility services with the R.styleable.AccessibilityService_canPerformGestures property can dispatch gestures. This class describes those gestures. Gestures are made up of one or more strokes. Gestures are immutable once built and will be dispatched to the specified display.

Spatial dimensions throughout are in screen pixels. Time is measured in milliseconds.
