Android FCM推送通知不存在'；应用程序在前台时不显示-反应本机

在Android上的react本机应用程序中，当我在调试模式下运行我的应用程序时，一切都正常工作，前台和后台推送通知都接收良好，没有任何错误。但当我生成签名的APK文件时，只接收后台推送，而不接收前台推送

我检查了android调试（Logcat），我可以看到Firebase发出的通知很好地接收到了，并且没有显示在前台

这是我的app.js代码，该代码正在运行

// Firebase Cloud Messages Start
async componentDidMount() {
const notificationOpen: NotificationOpen = await firebase
    .notifications()
    .getInitialNotification();
if (notificationOpen) {
    const action = notificationOpen.action;
    const notification: Notification = notificationOpen.notification;
    var seen = [];
    alert(
        JSON.stringify(notification.data, function(key, val) {
            if (val != null && typeof val == "object") {
                if (seen.indexOf(val) >= 0) {
                    return;
                }
                seen.push(val);
            }
            return val;
        })
    );
}
const channel = new firebase.notifications.Android.Channel(
    "test-channel",
    "Test Channel",
    firebase.notifications.Android.Importance.Max
).setDescription("My apps test channel");
// Create the channel
firebase.notifications().android.createChannel(channel);
this.notificationDisplayedListener = firebase
    .notifications()
    .onNotificationDisplayed((notification: Notification) => {
        // Process your notification as required
        // ANDROID: Remote notifications do not contain the channel ID. You will have to specify this manually if you'd like to re-display the notification.
    });    this.notificationListener = firebase
    .notifications()
    .onNotification((notification: Notification) => {
        // Process your notification as required
        notification.android
            .setChannelId("test-channel")
            .android.setSmallIcon("ic_launcher");
        firebase.notifications().displayNotification(notification);
    });
this.notificationOpenedListener = firebase
    .notifications()
    .onNotificationOpened((notificationOpen: NotificationOpen) => {
        // Get the action triggered by the notification being opened
        const action = notificationOpen.action;
        // Get information about the notification that was opened
        const notification: Notification = notificationOpen.notification;
        var seen = [];
        alert(
            JSON.stringify(notification.data, function(key, val) {
                if (val != null && typeof val == "object") {
                    if (seen.indexOf(val) >= 0) {
                        return;
                    }
                    seen.push(val);
                }
                return val;
            })
        );
        firebase
            .notifications()
            .removeDeliveredNotification(notification.notificationId);
    });}
    componentWillUnmount() {
        this.notificationDisplayedListener();
        this.notificationListener();
        this.notificationOpenedListener();
    }
    // END

我还收到了以下两个错误：

Could not find class ‘android.app.NotificationChannelGroup’, referenced from method io.invertase.firebase.notifications.RNFirebaseNotificationManager.parseChannelGroupMap
Could not find class ‘android.app.NotificationChannel’, referenced from method io.invertase.firebase.notifications.RNFirebaseNotificationManager.parseChannelMap

您好，您正在安卓O或更高版本的设备上测试吗？如果是，那么你必须为你的通知创建一个通知频道来显示。我已经在安卓4.4和8.0上测试了这段代码，但还没有收到通知。但这段代码在两台设备上的调试模式下都运行良好。您是在通知或数据对象中发送消息通知吗？很抱歉，我没有理解您的意思，我正在从Firebase控制台发送推送消息。您是在以下格式发送“数据”：{“标题”：“我要告诉您一个化学笑话”，“消息”：“但我知道我不会有任何反应”，“图像url:”}
