callType.name() : callType is null ) reason: reason time: callTime);SimpleDateFormat formatter new SimpleDateFormat(mm:ss);formatter.setTimeZone(TimeZone.getTimeZone(UTC));String callString 通话时长;callString formatter.format(callTime);Toast.makeText(MainActivity.this, callString, Toast.LENGTH_SHORT).show();//关闭任务栏通知stopBarNotify();}Overridepublic void onGenerateToken(String userId, String channelName, String appKey, EaseCallKitTokenCallback callback) {EMLog.d(TAG, onGenerateToken userId: userId channelName: channelName appKey: appKey);//获取声网TokengetAgoraToken(userId, channelName, callback);//创建服务开启任务栏通知(此处为了模拟,最好将openBarNotify()方法放在获取成功声网token后调用)openBarNotify();}Overridepublic void onReceivedCall(EaseCallType callType, String fromUserId, JSONObject ext) {EMLog.d(TAG, onRecivedCall callType.name() fromUserId: fromUserId);}Overridepublic void onCallError(EaseCallKit.EaseCallError type, int errorCode, String description) {EMLog.d(TAG, onCallError);}Overridepublic void onInViteCallMessageSent() { // LiveDataBus.get().with(DemoConstant.MESSAGE_CHANGE_CHANGE).postValue(new EaseEvent(DemoConstant.MESSAGE_CHANGE_CHANGE, EaseEvent.TYPE.MESSAGE));}Overridepublic void onRemoteUserJoinChannel(String channelName, String userName, int uid, EaseGetUserAccountCallback callback) {}};EaseCallKit.getInstance().setCallKitListener(callKitListener);}private void openBarNotify(){keepAppIntent new Intent(this, KeepAppLifeService.class);if (Build.VERSION.SDK_INT Build.VERSION_CODES.O) {//android8.0以上通过startForegroundService启动servicestartForegroundService(keepAppIntent);} else {startService(keepAppIntent);}}private void stopBarNotify(){if (keepAppIntent ! null) {stopService(keepAppIntent);}} 二、iOS想在后台时播放声音,需要在添加App plays audio or streams audio/video using AirPlay权限 1.Info.plist里找到选项Required background modes 添加App plays audio or streams audio/video using AirPlay 2.在SigningCapabilities - Background Modes - 勾选 Audio,AirPlay, and Picture in Picture 3.在AppDelegate.m中实现applicationDidEnterBackground代理方法 - (void)applicationDidEnterBackground:(UIApplication *)application{//环信已实现了进入后台的处理逻辑,如果要自己处理,可以参考下边注释代码[[EMClient sharedClient] applicationDidEnterBackground:application]; }#if Ease_UIKIT // - (void)applicationDidEnterBackground:(NSNotification *)notification { // if (!self.config.shouldRemoveExpiredDataWhenEnterBackground) { // return; // } // Class UIApplicationClass NSClassFromString(UIApplication); // if(!UIApplicationClass || ![UIApplicationClass respondsToSelector:selector(sharedApplication)]) { // return; // } // UIApplication *application [UIApplication performSelector:selector(sharedApplication)]; // __block UIBackgroundTaskIdentifier bgTask [application beginBackgroundTaskWithExpirationHandler:^{ // // Clean up any unfinished task business by marking where you // // stopped or ending the task outright. // [application endBackgroundTask:bgTask]; // bgTask UIBackgroundTaskInvalid; // }]; // // // Start the long-running task and return immediately. // [self deleteOldFilesWithCompletionBlock:^{ // [application endBackgroundTask:bgTask]; // bgTask UIBackgroundTaskInvalid; // }]; // } #endif 4.因为App plays audio or streams audio/video using AirPlay权限只能是音乐播放类与具有音视频通话场景的App使用,所以审核的时候需要在备注描述清楚使用该场景的方式.如果审核失败,可以录制视频在附件上传,然后等待苹果重新审核即可.如果录制的视频没有问题,那就坐等着审核通过了,good luck!
