IntentService stops working when app is removed from recent apps

Question

I am using geofence in my app and based on geofence events (Enter or Exit) I want to perform some action. Geofence documentation says that once you set geofence it will trigger events automatically and you can catch this events with IntentService. For that I have made intentservice as below:

GeofenceTransitionsIntentService.java

public class GeofenceTransitionsIntentService extends IntentService {

    Handler mHandler;
    public GeofenceTransitionsIntentService() {
        super("GeofenceTransitionsIntentService");
        mHandler = new Handler();
    }

    @Override
    public void onCreate() {
        super.onCreate();
        Log.e("JK-->>","service started!");
    }

    @Override
    protected void onHandleIntent(Intent intent) {

        Log.e("JK-->>","onHandel--->>");

        GeofencingEvent geofencingEvent = GeofencingEvent.fromIntent(intent);
        if (geofencingEvent.hasError()) {
            Log.e("JK-->>","geofenceEvent has error!");
            return;
        }

        int geofenceTransitionType = geofencingEvent.getGeofenceTransition();
        if (geofenceTransitionType == Geofence.GEOFENCE_TRANSITION_ENTER) {
            Log.e("JK-->>","enter!");
            mHandler.post(new DisplayToast(this,"Enter"));
        } else if (geofenceTransitionType == Geofence.GEOFENCE_TRANSITION_EXIT) {
            mHandler.post(new DisplayToast(this,"Exit"));
            Log.e("JK-->>","exit");
        }
    }

    public class DisplayToast implements Runnable {
        private final Context mContext;
        String mText;

        public DisplayToast(Context mContext, String text){
            this.mContext = mContext;
            mText = text;
        }

        public void run(){
            Toast.makeText(mContext, mText, Toast.LENGTH_SHORT).show();
        }
    }

}

Now, problem is that when app is open(No matter foreground or background) and I enter or exit in geofence it works fine and show me a toast message and logcat shows log but when I remove app from recent apps there is no toast message showing to me or no log is showing in logcat.

I have tried to find solution on google but mostly all answers suggests to use the service but if i am not wrong then IntentService stops itself automatically after work is done and start itself when any intent received. So, I think it's more efficient to use IntentService to do this task.

UPDATE I am registering geofence using following line of code.

geofencingClient.addGeofences(getGeofencingRequest(),getGeofencePendingIntent());

and in getGeofencePendingIntent() i am starting intent service using following line of code.

private PendingIntent getGeofencePendingIntent() {
        if(geofencePendingIntent != null)
            return geofencePendingIntent;
        Intent in = new Intent(SetProfileOnlineActivity.this,GeofenceTransitionsIntentService.class);
        geofencePendingIntent = PendingIntent.getService(SetProfileOnlineActivity.this,111451,in,PendingIntent.FLAG_UPDATE_CURRENT);
        return geofencePendingIntent;
    }

I had found an answer... there was no problem in my code and IntentService was also working perfectly but the mistake was in the testing. I was testing my application on android Oreo running device.

In android oreo google has updated their policy that in foreground they will send location updates any number of times but in background they will send location updates only few times in hour. The main reason behind it to save the bettery life of device.

For more information about android oreo location updates you can check out this documentation.
