Using your own monitor

You can also use your monitoring services and integrate with Places by using the Places extension APIs.

Registering Geofences

If you decide to use your monitoring services, register the geofences of the POIs around your current location by completing the following steps:

iOS

In iOS, complete the following steps:
  1. Pass the location updates that were obtained from the Core location services of the iOS to the Places extension.
  2. Use the getNearbyPointsOfInterest Places extension API to get the array of ACPPlacesPoi objects around the current location.
    - (void) locationManager: (CLLocationManager*) manager didUpdateLocations: (NSArray<CLLocation*>*) locations {
        [ACPPlaces getNearbyPointsOfInterest:currentLocation limit:10 callback: ^ (NSArray<ACPPlacesPoi*>* _Nullable nearbyPoi) {
            [self startMonitoringGeoFences:nearbyPoi];
        }];
    }
    
    
  3. Extract the information from the obtained ACPPlacesPOI objects and start monitoring those POIs.
    - (void) startMonitoringGeoFences: (NSArray*) newGeoFences {
        // verify if the device supports monitoring geofences
        // check for location permission
    
        for (ACPPlacesPoi * currentRegion in newGeoFences) {
            // make the circular region
            CLLocationCoordinate2D center = CLLocationCoordinate2DMake(currentRegion.latitude, currentRegion.longitude);
            CLCircularRegion* currentCLRegion = [[CLCircularRegion alloc] initWithCenter:center
                                                                                  radius:currentRegion.radius
                                                                              identifier:currentRegion.identifier];
            currentCLRegion.notifyOnExit = YES;
            currentCLRegion.notifyOnEntry = YES;
    
            // start monitoring the new region
            [_locationManager startMonitoringForRegion:currentCLRegion];
        }
    }
    
    

Android

  1. Pass the location updates that were obtained from the Google Play services or the Android location services to the Places Extension.
  2. Use the getNearbyPointsOfInterest Places Extension API to get the list of PlacesPoi objects around the current location.
    LocationCallback callback = new LocationCallback() {
        @Override
        public void onLocationResult(LocationResult locationResult) {
            super.onLocationResult(locationResult);
    
            Places.getNearbyPointsOfInterest(currentLocation, 10, new AdobeCallback<List<PlacesPOI>>() {
                @Override
                public void call(List<PlacesPOI> pois) {
                    starMonitoringGeofence(pois);
                }
            });
        }
    };
    
    
  3. Extract the data from the obtained PlacesPOI objects and start monitoring those POIs.
    private void startMonitoringFences(final List<PlacesPOI> nearByPOIs) {
        // check for location permission
        for (PlacesPOI poi : nearByPOIs) {
            final Geofence fence = new Geofence.Builder()
                .setRequestId(poi.getIdentifier())
                .setCircularRegion(poi.getLatitude(), poi.getLongitude(), poi.getRadius())
                .setExpirationDuration(Geofence.NEVER_EXPIRE)
                .setTransitionTypes(Geofence.GEOFENCE_TRANSITION_ENTER |
                                    Geofence.GEOFENCE_TRANSITION_EXIT)
                .build();
            geofences.add(fence);
        }
    
        GeofencingRequest.Builder builder = new GeofencingRequest.Builder();
        builder.setInitialTrigger(GeofencingRequest.INITIAL_TRIGGER_ENTER);
        builder.addGeofences(geofences);
        builder.build();
        geofencingClient.addGeofences(builder.build(), geoFencePendingIntent)
    }
    
    
Calling the getNearbyPointsOfInterest API results in a network call that gets the location around the current location.
You should call the API sparingly or only when there is significant location change of the user.

Posting Geofence Events

iOS

In iOS, call the processGeofenceEvent Places API in the CLLocationManager delegate. This API notifies you whether the user has entered or exited a specific region.
- (void) locationManager:(CLLocationManager *)manager didEnterRegion:(CLRegion *)region {
    [ACPPlaces processRegionEvent:region forRegionEventType:ACPRegionEventTypeEntry];
}

- (void) locationManager:(CLLocationManager *)manager didExitRegion:(CLRegion *)region {
    [ACPPlaces processRegionEvent:region forRegionEventType:ACPRegionEventTypeExit];
}

Android

In Android, call the processGeofence method along with the appropriate transition event in your Geofence broadcast receiver. You may want to curate the list of geofences received to prevent duplicate entries/exits.
void onGeofenceReceived(final Intent intent) {
    // do appropriate validation steps for the intent
    ...

    // get GeofencingEvent from intent
    GeofencingEvent geoEvent = GeofencingEvent.fromIntent(intent);

    // get the transition type (entry or exit)
    int transitionType = geoEvent.getGeofenceTransition();

    // validate your geoEvent and get the necessary Geofences from the list
    List<Geofence> myGeofences = geoEvent.getTriggeringGeofences();

    // process region events for your geofences
    for (Geofence geofence : myGeofences) {
        Places.processGeofence(geofence, transitionType);
    }
}
