android - E/FirebaseInstanceId : Error while delivering the message: ServiceIntent not found

Question

首先，我已将 FirebaseAnalytics 添加到我的 Android Unity 项目中，并且在测试中运行良好。然后，当我添加 FirebaseMessaging 并构建应用程序并从 FireBase 面板发送消息时，该消息将不会显示在设备/模拟器上，并且我在 Logcat 中收到此错误:

E/FirebaseInstanceId: Failed to resolve target intent service, skipping classname enforcement

1722-4448/system_process W/ActivityManager: Unable to start service Intent { act=com.google.firebase.MESSAGING_EVENT pkg=pack_name (has extras) } U=0: not found

E/FirebaseInstanceId: Error while delivering the message: ServiceIntent not found.

有一个主题here没有具体的问题答案。

我关注了 FireBase walkthrough将 FirebaseMessaging.unitypackage 添加到我的项目中，并据此将这些行添加到我的 list 中:

<!-- The MessagingUnityPlayerActivity is a class that extends
     UnityPlayerActivity to work around a known issue when receiving
     notification data payloads in the background. -->
 <activity android:name="com.google.firebase.MessagingUnityPlayerActivity" android:configChanges="fontScale|keyboard|keyboardHidden|locale|mnc|mcc|navigation|orientation|screenLayout|screenSize|smallestScreenSize|uiMode|touchscreen">
   <intent-filter>
     <action android:name="android.intent.action.MAIN" />
     <category android:name="android.intent.category.LAUNCHER" />
   </intent-filter>
   <meta-data android:name="unityplayer.UnityActivity" android:value="true" />
 </activity>
 <service android:name="com.google.firebase.messaging.MessageForwardingService" android:exported="false" />

附注:

在 @jeevashankar 答案中添加提到的服务到我的 list 后，当通知到达时，我收到此错误:

E/BufferQueueProducer: [SurfaceView - pack_name/com.google.firebase.MessagingUnityPlayerActivity#0] query: BufferQueue has been abandoned [SurfaceView - /com.google.firebase.MessagingUnityPlayerActivity#0] connect: BufferQueue has been abandoned E/BufferQueueProducer: [SurfaceView - pack_name/com.google.firebase.MessagingUnityPlayerActivity#0]

更新: 我在一个空的 Unity 项目中测试了 FirebaseMessaging，并在模拟器/设备上进行了测试，它一直工作到 Android 7.1.1。但在 Android 8 (API 26) 及更高版本中会出现此错误并且不会收到消息:

system_process E/NotificationService: No Channel found for pkg=, channelId=null, id=0, tag=campaign_collapse_key_4015583716848879920, opPkg=, callingUid=10122, userId=0, incomingUserId=0, notificationUid=10122, notification=Notification(channel=null pri=0 contentView=null vibrate=null sound=null defaults=0x0 flags=0x10 color=0x00000000 vis=PRIVATE)

我也遇到了同样的问题:

E/FirebaseInstanceId: Error while delivering the message: ServiceIntent not found

过了一段时间，我通过在 list 中导出服务找到了解决方案

<service
    android:name=".MyMessagingService"
    android:exported="true" 
    tools:ignore="ExportedService" >

    <intent-filter>
        <action android:name="com.google.firebase.MESSAGING_EVENT" />
    </intent-filter>

</service>
