[Bug]: onNotificationReceived() not called

[himadri1266]

What happened?

I am unable to detect notifications in the onNotificationReceived() method of INotificationServiceExtension. This issue occurs whether the app is in the background or foreground. I am using the latest version of the OneSignal SDK, version "5.1.21".

Below is the code I have integrated:

1. build.gradle (app level):
implementation("com.onesignal:OneSignal:5.1.21")

2. AndroidManifest.xml:

<meta-data
     android:name="com.onesignal.NotificationServiceExtension"
     android:value="com.myapp.notification.NotificationService" />

3. NotificationService class:

package com.myapp.notification;

import android.util.Log;

import com.onesignal.notifications.IDisplayableMutableNotification;
import com.onesignal.notifications.INotificationReceivedEvent;
import com.onesignal.notifications.INotificationServiceExtension;

public class NotificationService implements INotificationServiceExtension {
    private String TAG = "NotificationService";

    @Override
    public void onNotificationReceived(INotificationReceivedEvent event) {
        IDisplayableMutableNotification notification = event.getNotification();
        Log.d(TAG, "Title " + notification.getTitle());
        Log.d(TAG, "Body " + notification.getBody());

       event.preventDefault();
    }
}

Steps to reproduce?

1.Install the app on a mobile device.
2.Enable the notification service.
3.Send a test notification from the OneSignal dashboard.
4.Check the onNotificationReceived() method.

What did you expect to happen?

Whenever a notification arrives on the mobile device, the onNotificationReceived() method will be executed and will handle the API call from within that method.
