From 13bc105b80268c84ba4cfe7184c3ca8f827e54c0 Mon Sep 17 00:00:00 2001 From: Kyunglyul Hyun Date: Fri, 31 May 2019 17:00:36 +0900 Subject: [PATCH] MediaRouter: Make MR2M.CB.onRouteSelected to be called With this, MediaRouter2Manager.Callback.onRouteSelected will be called properly. This CL also adds provider id to MediaRoute2Info to distinguish routes with the same id from different providers.
