Firebase Cloud Messaging onMessageSent not called

Question

I am switching from GCM to FCM. I use it only to send messages to my server through FCM. I expanded FirebaseMessagingServiceto implement callbacks. For example, it onSendError()works just fine, but it onMessageSent()never executes ... I don’t know how relevant this is, but I send the line “ack” from my server when the message is received.

My FirebaseMessegingService class:

public class FCMListenerService extends FirebaseMessagingService {

    public FCMListenerService() {
        super();
    }

    @Override
    public void onDeletedMessages() {
        Log.d("wouter", "onDeletedMessages: ");
        super.onDeletedMessages();
    }

    @Override
    public void onMessageSent(String msgID) {
        Log.e("wouter", "##########onMessageSent: " + msgID );
        super.onMessageSent(msgID);
        Database database = new Database(this);
        database.confirmFCMMessageSend(msgID);
        database.closeDatabase();
    }

    @Override
    public void onSendError(String msgID, Exception exception) {
        Log.e("wouter", "onSendError ", exception );
        super.onSendError(msgID, exception);
        Database database = new Database(this);
        database.eraseFCMMsgIDFromFGMMessageLog(msgID);
        database.closeDatabase();
    }

    @Override
    public void onMessageReceived(RemoteMessage remoteMessage) {
        super.onMessageReceived(remoteMessage);
    }
}

And the corresponding part of my manifest:

<service android:name=".FCM.FCMListenerService"
    android:exported="false">
    <intent-filter>
        <action android:name="com.google.firebase.MESSAGING_EVENT"/>
    </intent-filter>
</service>

RemoteMessage myMessage = new RemoteMessage.Builder(SENDER_ID + "@gcm.googleapis.com").setMessageId(id).setData(data).setTtl(86400).build();
