应用程序在 Android 上处于前台时不显示 Amazon Pinpoint 推送通知

Question

我正在使用 Firebase 通过 Pinpoint 推送通知。

当应用程序不在前台时，我能够接收推送通知。但是当应用程序打开时我没有收到它。

我查看了 PushListenerService 代码，它有这样的内容：

 @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;
    }

我想玩 if 语句（前台应用程序），这会给我正确的结果。但事实证明，sdk 内部有逻辑，如果它在前台，则不显示通知。

这里有一个来自 SDK 的小 sn-p

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 是应用程序处于前台时未显示通知的原因。有没有其他方法可以绕过这个？除了提取信息和创建我自己的通知之外？

我找不到任何合适的文档。谁能帮我解决这个问题？

这并不神秘 - 这是设计使然。当应用程序在前台并且您在 PushListenerService 中的代码发送本地广播时，Amazon SDK 不会创建相应的通知。
