SDKsHarmonyOS商业版

处理通话事件

集中监听邀请、接听、参与者和挂断等通话状态变化。

通话状态层应集中注册信令生命周期和参与者事件。所有事件都带有结构化载荷，可按 invitation.roomID 识别通话。

const unsubscribeParticipantDisconnected = sdk.on(
  OpenIMSDKEvent.EventOnRoomParticipantDisconnected,
  handleParticipantDisconnected,

export function removeCallListeners(): void {
  unsubscribeIncoming();
  unsubscribeAccepted();
  unsubscribeAcceptedElsewhere();
  unsubscribeRejected();
  unsubscribeRejectedElsewhere();
  unsubscribeCancelled();
  unsubscribeTimeout();
  unsubscribeHangUp();
  unsubscribeParticipantConnected();
  unsubscribeParticipantDisconnected();
}

其他设备接听或拒绝时，当前设备应关闭重复来电入口。取消、超时和挂断的本地清理必须可重复执行。参与者事件返回当前房间相关参与者资料，但媒体轨道状态仍以所接入媒体引擎为准。退出账号或销毁通话状态层时移除监听。
