使用 xamarin forms 使用 android apilevel 33 构建应用程序时未收到 firebase 通知

Question

我正在为我的 android 项目使用 xamarin.forms。在将目标 api 级别从 29 更新到 33 之前，通知对我来说工作正常。更新后，没有收到 firebase 通知。这是我的代码： AndroidManifest.xml：

<receiver android:name="com.google.firebase.iid.FirebaseInstanceIdInternalReceiver" android:exported="false" />
<receiver android:name="com.google.firebase.iid.FirebaseInstanceIdReceiver" android:exported="true" android:permission="com.google.android.c2dm.permission.SEND">
<intent-filter>
<action android:name="com.google.android.c2dm.intent.RECEIVE" />
<action android:name="com.google.android.c2dm.intent.REGISTRATION" />
<category android:name="${applicationId}" />
</intent-filter>
</receiver>
<service android:name="crc6494e14b9856016c30.PNFirebaseMessagingService" android:exported="false">
<intent-filter>
<action android:name="com.google.firebase.MESSAGING_EVENT" />
</intent-filter>
</service>
<service
 android:name=".MyFirebaseMessagingService"
 android:exported="false">
<intent-filter>
<action android:name="com.google.firebase.MESSAGING_EVENT" />
</intent-filter>
</service>

MyFirebaseMessagingService.cs：

using Android.App;
using Android.Content;
using Android.Graphics;
using Android.Mtp;
using Android.OS;
using Android.Support.V4.App;
using Firebase.Iid;
using Firebase.Messaging;
using MyPrj.Helper;
using MyPrj.Repository;
using System;
using System.Text.RegularExpressions;

namespace MyPrj.Droid.Services
{

 [Service(Name = "com.fdtrucker.app.MyFirebaseMessagingService", Exported = true)]
 [IntentFilter(new[] { "com.google.firebase.MESSAGING_EVENT" })]
 public class MyFirebaseMessagingService : FirebaseMessagingService
 {
 AppCenterDataProvider appCenterLog = AppCenterDataProvider.GetInstance();
 Logger Logs = Logger.GetInstance();
 const string TAG = "MyFirebaseMsgService";
 public const string PRIMARY_CHANNEL = "default";
 public override void OnMessageReceived(RemoteMessage message)
 {
 try
 {
 appCenterLog.TrackError("OnMessageReceived:", "", null);
 Android.Util.Log.Debug(TAG, "From: " + message.From);
 Android.Util.Log.Debug(TAG, "Notification Message Body: " + message.GetNotification().Body);
 if (message.Data.Keys.Count > 0)
 {
 var name = message.Data["key2"];
 if (string.IsNullOrEmpty(name))
 {
 SendNotifications(message);
 }
 }
 else
 {
 SendNotifications(message);
 }
 }
 catch (Exception ex)
 {
 Logger.GetInstance().LogCreate("Droid/Services/MyFirebaseMessagingService/OnMessageReceived/Exceptionn: " + ex.Message);
 AppCenterDataProvider.GetInstance().TrackError("Droid/Services/MyFirebaseMessagingService/OnMessageReceived/Exception", "", ex);
 }
 }
 public void SendNotifications(RemoteMessage message)
 {
 try
 {
 NotificationManager manager = (NotificationManager)GetSystemService(NotificationService);
 var seed = Convert.ToInt32(Regex.Match(Guid.NewGuid().ToString(), @"\d+").Value);
 int id = new Random(seed).Next(000000000, 999999999);
 var push = new Intent();
 var fullScreenPendingIntent = PendingIntent.GetActivity(this, 0,
 push, PendingIntentFlags.UpdateCurrent| PendingIntentFlags.Mutable);
 NotificationCompat.Builder notification;
 if (Build.VERSION.SdkInt >= BuildVersionCodes.O)
 {
 var chan1 = new NotificationChannel(PRIMARY_CHANNEL,
 new Java.Lang.String("Primary"), NotificationImportance.High);
 chan1.LightColor = Color.Green;
 manager.CreateNotificationChannel(chan1);
 notification = new NotificationCompat.Builder(this, PRIMARY_CHANNEL);
 }
 else
 {
#pragma warning disable CS0618 // Type or member is obsolete
 notification = new NotificationCompat.Builder(this);
#pragma warning restore CS0618 // Type or member is obsolete
 }
 notification.SetContentIntent(fullScreenPendingIntent)
 .SetContentTitle(message.GetNotification().Title)
 .SetContentText(message.GetNotification().Body)
 .SetLargeIcon(BitmapFactory.DecodeResource(Resources, Resource.Drawable.icon))
 .SetSmallIcon(Resource.Drawable.icon_transparent)
 .SetStyle((new NotificationCompat.BigTextStyle()))
 .SetPriority(NotificationCompat.PriorityHigh)
 .SetColor(0x0a384a)
 .SetAutoCancel(true);
 manager.Notify(id, notification.Build());
 }
 catch (Exception ex)
 {
 Logger.GetInstance().LogCreate("Droid/Services/MyFirebaseMessagingService/SendNotifications/Exceptionn: " + ex.Message);
 AppCenterDataProvider.GetInstance().TrackError("Droid/Services/MyFirebaseMessagingService/SendNotifications/Exception", "", ex);
 }
 }
 }
}

我在设备日志中收到如下错误：

Time Device Name Type PID Tag Message 04-17 11:36:55.532 小米 21091116I 警告 26745 Firebase 安装错误 与 Firebase 安装服务器 API 通信。 HTTP 响应：[403 禁止：{ “错误”：{ “代码”：403，“消息”： “请求此 API firebaseinstallations.googleapis.com 方法 google.firebase.installations.v1.FirebaseInstallationsService.CreateInstallation 被阻止了。”, “status”: “PERMISSION_DENIED”, “details”: [ { “@type”：“type.googleapis.com/google.rpc.ErrorInfo”，“原因”： “API_KEY_SERVICE_BLOCKED”，“域”：“googleapis.com”，“元数据”：{ “消费者”：“项目/ 821562894021”，“服务”： “firebaseinstallations.googleapis.com” } } ] }

任何人都请帮我解决这个问题。
