Android模拟器无法接收Firebase Cloud Messaging推送通知求助

尝试将Firebase Cloud Messaging集成到应用中，试过所有解决方案后，通知仍无法送达。控制台发送通知时仅显示特定日志，模拟器版本为Android 13（API 33）。以下是相关代码及信息：

FCMNotificationService.java #

package com.example.myapp;


import android.app.NotificationChannel;

import android.content.Intent;
import android.content.pm.PackageManager;

public class FCMNotificationService extends FirebaseMessagingService {

    @Override
    public void onMessageReceived(RemoteMessage remoteMessage) {
        System.out.println("я тут");

        if (remoteMessage.getNotification()!=null){
            String notificationBody = remoteMessage.getNotification().getBody();
            String notificationTitle = remoteMessage.getNotification().getTitle();
            sendNotification(notificationTitle, notificationBody);
        }
    }


    private void sendNotification(String title, String body) {
        Intent intent = new Intent(this, MainActivity.class);
        intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
        PendingIntent pendingIntent = PendingIntent.getActivity(this, 0, intent,
                PendingIntent.FLAG_IMMUTABLE);

        String channelId = "fcm_default_channel";
        Uri defaultSoundUri = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
        NotificationCompat.Builder notificationBuilder =
                new NotificationCompat.Builder(this, channelId)
                        .setSmallIcon(R.mipmap.ic_launcher)
                        .setContentTitle(title)
                        .setContentText(body)
                        .setAutoCancel(true)
                        .setSound(defaultSoundUri)

        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
            NotificationChannel channel = new NotificationChannel(channelId,
                    "Channel human readable title",
                    NotificationManager.IMPORTANCE_DEFAULT);
            notificationManager.createNotificationChannel(channel);
        }

        notificationManager.notify(0, notificationBuilder.build());
    }
}

MainActivity中添加的通知通道创建代码 #

为解决“AndroidManifest.xml中设置的通知通道未被应用创建，将使用默认值”问题，在MainActivity中添加了以下代码：

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
            NotificationManager notificationManager = getSystemService(NotificationManager.class);
            CharSequence name = getString(R.string.default_notification_channel_name);
            String description = getString(R.string.default_notification_channel_description);
            int importance = NotificationManager.IMPORTANCE_DEFAULT;
            NotificationChannel channel = new NotificationChannel(getString(R.string.default_notification_channel_id), name, importance);
            channel.setDescription(description);
            notificationManager.createNotificationChannel(channel);
        }

已尝试在Manifest中添加多项配置，但均未解决问题，恳请提供帮助。
