Known Direct Subclasses |
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.
