parse-platform - Xamarin.Android 异常与 FCM & Parse

Question

我能够实现 Firebase 通知并成功地从 Firebase 控制台向客户端发送通知。当我使用 Parse SDK 通过 Parse Dashboard 发送通知时，就会出现问题。我正在使用 Xamarin.Android，而带有 FCM 和 Parse 的 Native Android 的文档并不完整。我注意到通过 Parse Dashboard 发送通知时，客户端出现以下异常：

Java.Lang.RuntimeException: Unable to instantiate service com.parse.fcm.ParseFirebaseMessagingService: java.lang.ClassNotFoundException: Didn't find class 

当解析文档告诉我在下面实现以下清单时：

<?xml version="1.0" encoding="utf-8"?>

            </intent-filter>
        </receiver>
        <service android:name="com.parse.fcm.ParseFirebaseInstanceIdService" android:exported="true">

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

        </service>
        <receiver android:name="com.parse.ParsePushBroadcastReceiver" android:exported="false">

                <action android:name="com.parse.push.intent.RECEIVE" />
                <action android:name="com.parse.push.intent.DELETE" />
                <action android:name="com.parse.push.intent.OPEN" />
            </intent-filter>
        </receiver>
    </application>
</manifest>

想知道我是否缺少任何东西来让 Xamarin.Android + Parse SDK + FCM 工作。谢谢。
