Geofence Transition onHandleIntent is background but Oreo will allow it?

Question

With Oreo, when handling geofence transition event in onHandleIntent() are we required to start immediately a Foreground service or can we handle needed work inside onHandleIntent() function (which my understanding runs in the background but should not be allowed in Oreo):

public class GeofenceTransitionsIntentService extends IntentService {
    @Override
    protected void onHandleIntent(Intent intent) {
      //Do work here...
    }
}

vs.

public class GeofenceTransitionsIntentService extends IntentService {
    @Override
    protected void onHandleIntent(Intent intent) {
        Intent startIntent = new Intent(this, ForegroundServices.class);
        this.startForegroundService(startIntent); //and do needed work 
        //inside the Foreground service
    }
}

Thanks!

Use a JobIntentService instead (in Kotlin):

class GeofenceTransitionsIntentService : JobIntentService() {
    override fun onHandleWork(intent: Intent) {
        val geofencingEvent = GeofencingEvent.fromIntent(intent)
        // ...
    }
}
