Ionic 2+ Cordova OneSignal NotificationExtenderService

问题

I'm writing an application in Ionic 3 that uses the Cordova OneSignal plugin (onesignal-cordova-plugin 2.8.4).

Scenario: The application is killed and a push notification is received: I need to know that the notification was received BEFORE the notification is clicked or the application is opened.

The plan is to write code that runs as soon as a notification is received that will send a "receipt" to the main server. This is only happening if the Ionic application is running in the background or opened. If the Ionic application is "killed" code doesn't run.

I have followed the steps on this post to extend the NotificationExtenderService. I was able to add the Java file that I created to the AndroidManifest.xml file and the compiler seems to find it. I get the following error :

[cordova]    protected boolean onNotificationProcessing(OSNotificationReceivedResult receivedResult) {
[cordova]                                               ^
[cordova]   symbol:   class OSNotificationReceivedResult
[cordova]   location: class NotificationExtenderExample

My NotificationExtender.java file (this file is at platforms\android\app\src\main\java\com\plugin\gcm\NotificationExtenderExample.java)

import android.support.v4.app.NotificationCompat;
import com.onesignal.OSNotificationPayload;
import com.onesignal.NotificationExtenderService;
import java.math.BigInteger;

public class NotificationExtenderExample extends NotificationExtenderService {
   @Override
   protected boolean onNotificationProcessing(OSNotificationReceivedResult receivedResult) {
      OverrideSettings overrideSettings = new OverrideSettings();
      overrideSettings.extender = new NotificationCompat.Extender() {
         @Override
         public NotificationCompat.Builder extend(NotificationCompat.Builder builder) {
            // Sets the background notification color to Green on Android 5.0+ devices.
            return builder.setColor(new BigInteger("FF00FF00", 16).intValue());
         }
      };

      OSNotificationDisplayedResult displayedResult = displayNotification(overrideSettings);
      Log.d("OneSignalExample", "Notification displayed with id: " + displayedResult.androidNotificationId);

      return true;
   }
}

I added the following code to my AndroidManifest.xml (this file is at platforms\android\app\src\main\AndroidManifest.xml)

    <service android:exported="false" android:name=".NotificationExtenderExample" android:permission="android.permission.BIND_JOB_SERVICE">
        <intent-filter>
            <action android:name="com.onesignal.NotificationExtender" />
        </intent-filter>
    </service>
