设置通知侦听器

本主题介绍如何设置和删除云眼灰度实验 Android SDK 的通知侦听器。

通知侦听器触发您在 SDK 中触发某些操作时定义的回调函数。

最常见的用例是将所有灰度标帜决策的流发送到分析提供商或内部数据仓库,以将其与您拥有的有关用户的其他数据联接。

通知侦听器类型

有关通知侦听器类型和用例的更多信息,请参阅通知侦听器

有关代码示例,请参阅以下部分。

添加和删除所有通知侦听器

下面的示例代码演示如何添加侦听器、删除侦听器、删除特定类型的所有侦听器(例如所有决策侦听器)以及删除所有侦听器。

KotlinJava

// Add Notification Listener (LogEvent) val notificationId = eyeofcloudClient.addLogEventNotificationHandler { logEvent: LogEvent -> Log.d("Eyeofcloud", "event dispatched: $logEvent") } // Remove Notification Listener eyeofcloudClient.notificationCenter!!.removeNotificationListener(notificationId) // Remove all Notification Listeners eyeofcloudClient.notificationCenter!!.clearAllNotificationListeners() // Remove all Notification Listeners of a certain type eyeofcloudClient.notificationCenter!!.clearNotificationListeners(DecisionNotification::class.java)

// Add Notification Listener (LogEvent) int notificationId = eyeofcloudClient.addLogEventNotificationHandler(logEvent -> { Log.d("Eyeofcloud", "event dispatched: " + logEvent); }); // Remove Notification Listener eyeofcloudClient.getNotificationCenter().removeNotificationListener(notificationId); // Remove all Notification Listeners eyeofcloudClient.getNotificationCenter().clearAllNotificationListeners(); // Remove all Notification Listeners of a certain type eyeofcloudClient.getNotificationCenter().clearNotificationListeners(DecisionNotification.class);

设置每种类型的通知侦听器

下面的示例代码演示如何设置每种类型的通知侦听器。

KotlinJava

// SET UP DECISION NOTIFICATION LISTENER val notificationId1 = eyeofcloudClient.addDecisionNotificationHandler { notification: DecisionNotification -> // Access type on decisionObject to get type of decision val decisionType = notification.type if (decisionType === "flag") { val flagDecisionInfo = notification.decisionInfo val flagKey = flagDecisionInfo["flagKey"] as? String val enabled = flagDecisionInfo["enabled"] as? Boolean val decisionEventDispatched = flagDecisionInfo["decisionEventDispatched"] as? Boolean // Send data to analytics provider here } } // SET UP LOG EVENT NOTIFICATION LISTENER val notificationId2 = eyeofcloudClient.addLogEventNotificationHandler { notification: LogEvent -> // process the logEvent object here (send to analytics provider, audit/inspect data) } // SET UP EYEOFCLOUD CONFIG NOTIFICATION LISTENER val notificationId3 = eyeofcloudClient.addUpdateConfigNotificationHandler { notification: UpdateConfigNotification -> val eyeofcloudConfig = eyeofcloudClient.eyeofcloudConfig } // SET UP TRACK LISTENER val notificationId4 = eyeofcloudClient.addTrackNotificationHandler { notification: TrackNotification -> // process the event here (send to analytics provider, audit/inspect data) }

// SET UP DECISION NOTIFICATION LISTENER int notificationId1 = eyeofcloudClient.addDecisionNotificationHandler(notification -> { // Access type on decisionObject to get type of decision String decisionType = notification.getType(); if (decisionType == "flag") { Map<String, ?> flagDecisionInfo = notification.getDecisionInfo(); String flagKey = (String) flagDecisionInfo.get("flagKey"); Boolean enabled = (Boolean) flagDecisionInfo.get("enabled"); Boolean decisionEventDispatched = (Boolean) flagDecisionInfo.get("decisionEventDispatched"); // Send data to analytics provider here } }); // SET UP LOG EVENT NOTIFICATION LISTENER int notificationId2 = eyeofcloudClient.addLogEventNotificationHandler(notification -> { // process the logEvent object here (send to analytics provider, audit/inspect data) }); // SET UP EYEOFCLOUD CONFIG NOTIFICATION LISTENER int notificationId3 = eyeofcloudClient.addUpdateConfigNotificationHandler(notification -> { EyeofcloudConfig eyeofcloudConfig = eyeofcloudClient.getEyeofcloudConfig(); }); // SET UP TRACK LISTENER int notificationId4 = eyeofcloudClient.addTrackNotificationHandler(notification -> { // process the event here (send to analytics provider, audit/inspect data) });
