當應用程序在 Android 上處於前台時不顯示 Amazon Pinpoint 推送通知

Question

我正在使用 Firebase 通過 Pinpoint 處理推送通知。

當應用程序不在前台時，我能夠收到推送通知。 但是當應用程序打開時我沒有收到它。

我查看了 PushListenerService 代碼，它有這樣的內容：

 @Override
public void onMessageReceived(RemoteMessage remoteMessage) {
    super.onMessageReceived(remoteMessage);
    Log.d(TAG, "Message: " + remoteMessage.getData());

    final NotificationClient notificationClient= NofiticaiontProvider.getNotificationClient();

    final NotificationDetails notificationDetails = NotificationDetails.builder()
            .from(remoteMessage.getFrom())
            .mapData(remoteMessage.getData())
            .intentAction(NotificationClient.FCM_INTENT_ACTION)
            .build();

    NotificationClient.CampaignPushResult pushResult = notificationClient.handleCampaignPush(notificationDetails);

    if (!NotificationClient.CampaignPushResult.NOT_HANDLED.equals(pushResult)) {
        /**
         The push message was due to a Pinpoint campaign.
         If the app was in the background, a local notification was added
         in the notification center. If the app was in the foreground, an
         event was recorded indicating the app was in the foreground,
         for the demo, we will broadcast the notification to let the main
         activity display it in a dialog.
         */
        if (NotificationClient.CampaignPushResult.APP_IN_FOREGROUND.equals(pushResult)) {
            /* Create a message that will display the raw data of the campaign push in a dialog. */

            final HashMap<String, String> dataMap = new HashMap<>(remoteMessage.getData());
            broadcast(remoteMessage.getFrom(), dataMap);
        }
        return;
    }

我想過使用 if 語句（前台應用程序之一），這會給我正確的結果。 但事實證明，sdk 內部有邏輯，如果它在前台，則不顯示通知。

這是 SDK 中的一個小片段

public final NotificationClient.CampaignPushResult handleCampaignPush(NotificationDetails notificationDetails) {
    final String from = notificationDetails.getFrom();
    final Bundle data = notificationDetails.getBundle();
    final Class<?> targetClass = notificationDetails.getTargetClass();
    String intentAction = notificationDetails.getIntentAction();
    notificationChannelId = notificationDetails.getNotificationChannelId();

    // Check if push data contains a Campaign Id
    if (data == null || !data.containsKey(CAMPAIGN_ID_PUSH_KEY)) {
        return NotificationClient.CampaignPushResult.NOT_HANDLED;
    }

    final boolean isAppInForeground = appUtil.isAppInForeground();

    final String imageUrl = data.getString(CAMPAIGN_IMAGE_PUSH_KEY);
    final String imageIconUrl = data.getString(CAMPAIGN_IMAGE_ICON_PUSH_KEY);
    final String imageSmallIconUrl = data.getString(CAMPAIGN_IMAGE_SMALL_ICON_PUSH_KEY);
    final Map<String, String> campaignAttributes = new HashMap<String, String>();

    campaignAttributes.put(CAMPAIGN_ID_ATTRIBUTE_KEY, data.getString(CAMPAIGN_ID_PUSH_KEY));
    campaignAttributes.put(CAMPAIGN_TREATMENT_ID_ATTRIBUTE_KEY, data.getString(CAMPAIGN_TREATMENT_ID_PUSH_KEY));
    campaignAttributes.put(CAMPAIGN_ACTIVITY_ID_ATTRIBUTE_KEY, data.getString(CAMPAIGN_ACTIVITY_ID_PUSH_KEY));

    this.pinpointContext.getAnalyticsClient().setCampaignAttributes(campaignAttributes);
    log.info("Campaign Attributes are:" + campaignAttributes);

    if (AWS_EVENT_TYPE_OPENED.equals(from)) {
        return this.handleNotificationOpen(campaignAttributes, data);
    }

    // Create the push event.
    String eventType = null;
    if (isAppInForeground) {
        eventType = AWS_EVENT_TYPE_RECEIVED_FOREGROUND;
    } else {
        eventType = AWS_EVENT_TYPE_RECEIVED_BACKGROUND;
    }

可能 eventType 是應用程序處於前台時未顯示通知的原因。 有沒有其他方法可以繞過這個？ 除了提取信息和創建我自己的通知？

我找不到任何適當的文檔。 任何人都可以幫我解決這個問題嗎？

一切都讓我找到了這份 文件

沒有什么神秘之處 - 這是設計使然。 當應用程序處於前台並且您在 PushListenerService 中的代碼發送本地廣播時，Amazon SDK 不會創建相應的通知。
