DcsManager
//开启手机就启动服务，来视频信令，就发送广播启动view
ICall
onDisplayHint() //显示提示onConfirmDialog()//来电是否确定连接
（SDK）RTC SDK层
PeerConnectionEvents
onLocalDescription();onIceCandidate();onIceCandidatesRemoved();onIceConnected();onIceDisconnected();onPeerConnectionClosed();onPeerConnectionStatsReady();onPeerConnectionError();
（view）上层实现类图
（接口）为上层提供SDK DCS接口管理层
ParametersGroup
private String url;private String roomId;private boolean loopback;还有很多其他的参数。。。
ICallState
void onStartCall();//开始拨打void onCallSuccess();//拨打成功void onCallFailed(String msg);//拨打失败void onCallStateChanged();
DCS层与服务端长连接
ICallStatus
void onStartCall();//开始拨打void onCallSuccess();//拨打成功void onCallFailed(String msg);//拨打失败
