Just saw that you did this. Why exporting something we don't need to export?

[whywhat, 2016/10/06 18:18:48]

Because I didn't remember NON_EXPORTED_BASE ?

  public:
   virtual ~WebRemotePlaybackClient() = default;
 
   // Notifies the client that the media element state has changed.
   virtual void stateChanged(WebRemotePlaybackState) = 0;
 
   // Notifies the client of the remote playback device availability change.
   virtual void availabilityChanged(bool availability) = 0;
 
   // Notifies the client that the user cancelled the prompt shown via the API.
   virtual void promptCancelled() = 0;
 };
 
 }  // namespace blink
 
 #endif  // WebRemotePlaybackState_h
