Question

我正在使用Firebase通过Pinpoint进行推送通知。

当应用程序不在前台时，我能够接收推送通知。但是，当应用打开时，我没有收到。

我查看了PushListenerService代码，它的内容如下：

 @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;
    }

我想到玩if语句（在前景中为App），这将给我适当的结果。但是事实证明，SDK具有内部逻辑，如果它在前台，则不显示通知。

这是SDK的一小段内容

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;
    }

eventType可能是导致当应用程序处于前台状态时未显示通知的原因。是否有其他替代方法可以绕过此方法？除了提取信息并创建我自己的通知之外？

我找不到与此相关的任何文档。有人可以帮我吗？

一切都将我引向这个document

没有什么神秘的-这是设计使然。当应用程序处于前台状态，而您在PushListenerService中的代码发送本地广播时，Amazon SDK不会创建相应的通知。

当应用程序在Android上处于前台时，不会显示Amazon Pinpoint推送通知
