This document describes how to use the Call Status Callback of the TUICallKit component.
Call Status Monitoring
If your business needs to monitor the status of calls, such as the start and end of a call and other events during the call, you can refer to the following code:
Android(Kotlin)
Android(Java)
iOS(Swift)
iOS(Objective-C)
Flutter(Dart)
private val observer: TUICallObserver = object : TUICallObserver() {
    override fun onCallBegin(roomId: TUICommonDefine.RoomId?, callMediaType: TUICallDefine.MediaType?, callRole: TUICallDefine.Role?) {
    }
    override fun onCallEnd(roomId: TUICommonDefine.RoomId?, callMediaType: TUICallDefine.MediaType?, callRole: TUICallDefine.Role?, totalTime: Long) {
    }   
    override fun onUserNetworkQualityChanged(networkQualityList: MutableList<TUICommonDefine.NetworkQualityInfo>?) {    
    }
}
private fun initData() {
    TUICallEngine.createInstance(context).addObserver(observer)
}
private TUICallObserver observer = new TUICallObserver() {
    @Override
    public void onCallBegin(TUICommonDefine.RoomId roomId, TUICallDefine.MediaType callMediaType, TUICallDefine.Role callRole) {
    }
    public void onCallEnd(TUICommonDefine.RoomId roomId, TUICallDefine.MediaType callMediaType,TUICallDefine.Role callRole, long totalTime) {
    }
    public void onUserNetworkQualityChanged(List<TUICommonDefine.NetworkQualityInfo> networkQualityList) {
    }
};
﻿
private void initData(){
    TUICallEngine.createInstance(context).addObserver(observer);
}
import TUICallEngine
﻿
TUICallEngine.createInstance().addObserver(self)
﻿
public func onCallBegin(roomId: TUIRoomId, callMediaType: TUICallMediaType, callRole: TUICallRole) {
﻿
}
public func onCallEnd(roomId: TUIRoomId, callMediaType: TUICallMediaType, callRole: TUICallRole, totalTime: Float) {
﻿
}
public func onUserNetworkQualityChanged(networkQualityList: [TUINetworkQualityInfo]) {
﻿
}
#import <TUICallEngine/TUICallEngine.h>
﻿
[[TUICallEngine createInstance] addObserver:self];
﻿
- (void)onCallBegin:(TUIRoomId *)roomId callMediaType:(TUICallMediaType)callMediaType callRole:(TUICallRole)callRole {
﻿
}
- (void)onCallEnd:(TUIRoomId *)roomId callMediaType:(TUICallMediaType)callMediaType callRole:(TUICallRole)callRole totalTime:(float)totalTime {
﻿
}
- (void)onUserNetworkQualityChanged:(NSArray<TUINetworkQualityInfo *> *)networkQualityList {
﻿
}
TUICallObserver observer = TUICallObserver(
    onError: (int code, String message) {
      // Your callback handling logic    
    }, onCallBegin: (TUIRoomId roomId, TUICallMediaType callMediaType, TUICallRole callRole) {
      // Your callback handling logic    
    }, onCallEnd: (TUIRoomId roomId, TUICallMediaType callMediaType, TUICallRole callRole, double totalTime) {  
      // Your callback handling logic    
    },, onUserNetworkQualityChanged: (List<TUINetworkQualityInfo> networkQualityList) {
      // Your callback handling logic    
    }, onCallReceived: (String callerId, List<String> calleeIdList, String groupId, TUICallMediaType callMediaType) {
      // Your callback handling logic    
    }
    …
))
﻿
TUICallEngine.instance.addObserver(observer);
Note:
On the Android platform, when setting TUICallObserver to monitor callbacks, ensure the callback's class is not cleared. For example, it's not recommended to add monitoring in LoginActivity because the callback will be cleared when LoginActivity is terminated; it's advised to monitor in the Application class or the main interface.
