+This library (com.android.media.remotedisplay.jar) is a shared java library
+containing classes required by unbundled remote display providers.
+
+--- Rules of this library ---
+o This library is effectively a PUBLIC API for unbundled remote display providers
+  that may be distributed outside the system image. So it MUST BE API STABLE.
+  You can add but not remove. The rules are the same as for the
+  public platform SDK API.
+o This library can see and instantiate internal platform classes, but it must not
+  expose them in any public method (or by extending them via inheritance). This would
+  break clients of the library because they cannot see the internal platform classes.
+
+This library is distributed in the system image, and loaded as
+a shared library. So you can change the implementation, but not
+the interface. In this way it is like framework.jar.
+
+--- Why does this library exists? ---
+
+Unbundled remote display providers (such as Cast) cannot use internal
+platform classes.
+
+This library will eventually be replaced when the media route provider
+infrastructure that is currently defined in the support library is reintegrated
+with the framework in a new API.  That API isn't ready yet so this
+library is a compromise to make new capabilities available to the system
+without exposing the full surface area of the support library media
+route provider protocol.

+This directory contains sample code to test system integration with
+remote display providers using the API declared by the
+com.android.media.remotedisplay.jar library.
+
+--- DESCRIPTION ---
+
+The application registers a service that publishes a few different
+remote display routes.  Behavior can be controlled by modifying the
+code.
+
+To exercise the provider, use System UI features for connecting to
+wireless displays or launch an activity that uses the MediaRouter,
+such as the PresentationWithMediaRouterActivity in ApiDemos.
+
+This code is mainly intended for development and not meant to be
+used as an example implementation of a robust remote display provider.
