ViewAnnotationManager

interface ViewAnnotationManager

Manager API to control View Annotations.

View annotations are Android Views that are drawn on top of the MapView and bound to some Geometry (only Point is supported for now). In case some view annotations intersect on the screen Z-index is based on addition order.

View annotations are invariant to map camera transformations however such properties as size, visibility etc could be controlled by the user using update operation.

View annotations are not explicitly bound to any sources however ViewAnnotationOptions.associatedFeatureId could be used to bind given view annotation with some Feature by Feature.id meaning visibility of view annotation will be driven by visibility of given feature.

View annotation manager instance is destroyed automatically when MapView.onDestroy is called.
