Interface ActionHandlerRegistry

public interface ActionHandlerRegistry

Defines an interface for a registry of ActionHandler objects to be used for inter-SDK actions, such as starting an android.app.Activity from one SDK, in another SDK, without any dependency between them. ActionHandler objects can be added and removed from the registry using ActionHandlerRegistry.add(ActionHandler) and ActionHandlerRegistry.remove(ActionHandler), respectively. A query method, ActionHandlerRegistry.handlerByAction(String), returns the highest priority ActionHandler whose ActionHandler.canHandle(String) returned true.
