GeoFence alert does not show

问题

After adding a geofence using below code, Notification is not showing.Even onResult callback is returing the success.

Adding geofence in GoogleApiClientApi onConnected() callback method:

public void onConnected(Bundle bundle) {
        LocationServices.GeofencingApi.addGeofences(
                googleApiClient,
                getGeofencingRequest(),
                getGeofencePendingIntent()
        ).setResultCallback(this);
    }

Requesting Geofence:

private GeofencingRequest getGeofencingRequest() {
        geoFenceList.add(new Geofence.Builder()
                .setRequestId("myFence")
                .setCircularRegion(68.441630, 77.310587, 2.0f)
                .setTransitionTypes(Geofence.GEOFENCE_TRANSITION_ENTER)
                .setExpirationDuration(Geofence.NEVER_EXPIRE)
                .build());
        GeofencingRequest.Builder builder = new GeofencingRequest.Builder();
        builder.setInitialTrigger(GeofencingRequest.INITIAL_TRIGGER_ENTER);
        builder.addGeofences(geoFenceList);
        return builder.build();
    }

onResult() callback;

public void onResult(Status status) {
        if (status.isSuccess()){
            Toast.makeText(this,"Working",Toast.LENGTH_SHORT).show();//This Toast is showing/

        }else{
            Toast.makeText(this,"Not Working",Toast.LENGTH_SHORT).show();
        }
    }

Intent Service which triggers the Notification:

protected void onHandleIntent(Intent intent) {
        GeofencingEvent geofencingEvent = GeofencingEvent.fromIntent(intent);
        if (geofencingEvent.hasError()) {

            return;
        }
        int geofenceTransition = geofencingEvent.getGeofenceTransition();
        if (geofenceTransition == Geofence.GEOFENCE_TRANSITION_ENTER ||
                geofenceTransition == Geofence.GEOFENCE_TRANSITION_EXIT) {

            NotificationManager notificationManager = (NotificationManager) this.getSystemService(Context.NOTIFICATION_SERVICE);
            Intent intent1 = new Intent(this, MainActivity.class);
            intent.addFlags(Intent.FLAG_ACTIVITY_SINGLE_TOP | Intent.FLAG_ACTIVITY_CLEAR_TOP);
            PendingIntent pendingNotificationIntent = PendingIntent.getActivity(this, 0, intent1, PendingIntent.FLAG_UPDATE_CURRENT);

            Notification notification = new NotificationCompat.Builder(this)
                    .setSmallIcon(R.mipmap.ic_launcher)
                    .setContentTitle("Your Geo")
                    .setContentText("This is My geo")
                    .setContentIntent(pendingNotificationIntent)
                    .setPriority(NotificationCompat.PRIORITY_HIGH)
                    .setAutoCancel(true)
                    .build();
            notificationManager.notify(0, notification);
        } else {
        }    
    }

I think the IntentService is not inovked. Did I miss something?

here is my working code.. i hope its help u..

        }
    }

    private void onError(int i) {
        Log.e(TAG, "Geofencing Error: " + i);
    }
}

and make sure that you add this line in manifest file:

<service android:name=".AreWeThereIntentService" /> 

here is the link that i implemented in my project geofence alert
