public class ComponentInfo
extends PackageItemInfo

Base class containing information common to all application components (ActivityInfo, ServiceInfo). This class is not intended to be used by itself; it is simply here to share common definitions between all application components. As such, it does not itself implement Parcelable, but does provide convenience methods to assist in the implementation of Parcelable in subclasses.
