FirebaseMessagingService #onMessageReceived没有被调用

Question

Firebase Server sends notification, I get it, but my MyFirebaseMessagingService's onMessageReceived is not being called.

This is MyFirebaseMessagingService:

public class MyFirebaseMessagingService extends FirebaseMessagingService {

    private static String id;
    private static PSTrip trip;

    public void onMessageReceived(final RemoteMessage message) {
        Log.i("", "MyFirebaseMessagingService onMessageReceived");
        final Map data = message.getData();
        FcmService.triggerSmoochNotification(data, this);
        final Map bundle = data;
        Handler handler = new Handler(Looper.getMainLooper());
        handler.post(new Runnable() {
            @Override
            public void run() {
                Log.i("", "GLOBAL intances  before GCM:" + Realm.getGlobalInstanceCount(PSApplicationClass.Config));
                final Realm realm = Realm.getInstance(PSApplicationClass.Config);
                try {
                    final RealmResults < PSTrip > completed = realm.where(PSTrip.class).equalTo("status", "active").findAll();
                    if (completed != null && completed.size() > 0) {
                        id = new String(completed.get(0).getId());
                        trip = new PSTrip(completed.get(0));
                        realm.executeTransaction(new Realm.Transaction() {
                            @Override
                            public void execute(Realm realm) {
                                completed.deleteAllFromRealm();
                            }
                        });
                    }
                    generateNotificationStandard(MyFirebaseMessagingService.this, data.get("title"), message, null, null, false, false);
                } catch (Exception e) {
                    Utils.appendLog("GCMIntentService onMessageReceived error: " + e.getMessage(), "E", Constants.PUSH_NOTIFICATIONS);
                }
                realm.close();
            }
        });
    }
}

I am using this version of firebase:

implementation 'com.google.firebase:firebase-messaging:12.0.1'

And I have my FirebaseMessagingService declared in my AndroidManifest like this:

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

Somehow my notifications are shown, but my method is not being called. How can I make it so my messages are received and handled through this?

Also: the server uses this to send the data. Might this be the issue? https://github.com/jazzband/django-push-notifications

EDIT:

Also tried:

 <service android:name="nl.hgrams.passenger.MyFirebaseMessagingService">
        <intent-filter>
            <action android:name="com.google.firebase.MESSAGING_EVENT" />
        </intent-filter>
    </service>

as in to give the full path. but still nothing.

Answer 1

The server part of the app was trying to send as Notification Message. This is what was causing the issue, and after I figured this out, I talked with the backend guy, in order to change the code to use Data Message, and now it works
