ZRC Broadcast Intent Interfaces for ZRC status

1. INTRODUCTION

Zoom Rooms have several partners provide speaker devices that can run ZRC, these devices build-in Android System. Sometimes the system wants to indicate Zoom Rooms status to change LED, wake up the screen and so on. Even some devices have no direct link to ZR, but with the network connection, this needs ZRC to send the ZR's IP address to them by Android broadcast.
