Utilisation de Places Service sans surveillance de région principale

Les cas d’utilisation de votre application peuvent ne pas nécessiter une surveillance de région principale. Places Service peut toujours être utilisé pour intégrer les données de localisation de vos utilisateurs à d’autres produits Experience Platform.

Condition requise

Le développeur collectera l’emplacement de l’appareil à l’aide des API fournies par le système d’exploitation de la plateforme cible.

Pour utiliser Places Service sans surveillance de région principale :

1. Collecter l’emplacement de l’utilisateur

Le développeur de l’application doit collecter l’emplacement actuel de l’appareil à l’aide de la variable CoreLocation.framework (iOS) ou la variable Location API fournies par les services Google Play (Android).

Pour plus d’informations, consultez la documentation suivante :

• CoreLocation (Apple)
• API d’emplacement dans les services Google Play (Google)

2. Récupérer les points ciblés proches à partir du SDK

Après avoir obtenu l’emplacement de l’utilisateur, vous pouvez le transmettre au SDK pour obtenir une liste des points ciblés voisins.

Android

Voici un exemple de mise en oeuvre sous Android qui utilise une BroadcastReceiver:

public class LocationBroadcastReceiver extends BroadcastReceiver {
    static final String ACTION_LOCATION_UPDATE = "locationUpdate";
    @Override
    public void onReceive(Context context, Intent intent) {
        if (intent == null || context == null) {
            return;
        }

        final String action = intent.getAction();
        if (!ACTION_LOCATION_UPDATE.equals(action)) {
            return;
        }

        LocationResult result = LocationResult.extractResult(intent);
        if (result == null) {
            return;
        }

        Location currentLocation = result.getLastLocation();
        if (currentLocation == null) {
            return;
        }

        // ask the Places SDK for the 10 nearest Points of Interest based on the user's location
        Places.getNearbyPointsOfInterest(currentLocation, 10,
            new AdobeCallback<List<PlacesPOI>>() {
                @Override
                public void call(List<PlacesPOI> pois) {
                    // pois is the 10 nearest POIs based on the location
                }
            }, new AdobeCallback<PlacesRequestError>() {
                @Override
                public void call(PlacesRequestError placesRequestError) {
                    // Look for the placesRequestError and handle the error accordingly
                }
            }
        );
    }
}

Objective-C

Voici un exemple de mise en oeuvre pour iOS. Le code affiche l’implémentation de la variable locationManager:didUpdateLocations: dans la méthode CLLocationManagerDelegate:

- (void) locationManager:(CLLocationManager*)manager didUpdateLocations:(NSArray<CLLocation*>*)locations {
    // ask the Places SDK for the 10 nearest Points of Interest based on the user's location
    [ACPPlaces getNearbyPointsOfInterest:[locations lastObject] limit:10 callback:^(NSArray<ACPPlacesPoi *> * _Nullable nearbyPoi) {
        // nearbyPoi is the 10 nearest POIs based on the location
    } errorCallback:^(ACPPlacesRequestError result) {
        // log the error if we got one
        NSLog(@"error: %lu", (unsigned long)result);
    }];
}

Swift

Voici un exemple de mise en oeuvre pour iOS. Le code affiche l’implémentation de la variable locationManager(_:didUpdateLocations:) dans la méthode CLLocationManagerDelegate:

func locationManager(_ manager: CLLocationManager, didUpdateLocations locations: [CLLocation]) {
    // ask the Places SDK for the 10 nearest Points of Interest based on the user's location
    ACPPlaces.getNearbyPoints(ofInterest: locations.last!, limit: 10, callback: { (nearbyPoi) in
        // nearbyPoi is the 10 nearest POIs based on the location
    }) { (error) in
        // log the error if we have one
        print("error: \(error)")
    }
}

3. Joindre des données Places à vos requêtes Analytics

En appelant la fonction getNearbyPointsOfInterest API, le SDK Places mettra à disposition toutes les données POI pertinentes pour l’appareil via les éléments de données dans Launch. En utilisant une Joindre des données règle, les données Places peuvent être automatiquement ajoutées aux futures requêtes dans Analytics. Cela évite d’avoir besoin d’un appel ponctuel à Analytics au moment de la collecte de l’emplacement de l’appareil.

Voir Ajout du contexte d’emplacement aux requêtes Analytics pour en savoir plus sur cette rubrique.

Facultatif - Déclenchez les événements d’entrée lorsque l’utilisateur se trouve dans un point ciblé

La liste renvoyée par la variable getNearbyPointsOfInterest L’API contient objet personnalisé qui indiquent si l’utilisateur se trouve actuellement dans un point ciblé. Si l’utilisateur se trouve dans un point ciblé, le SDK peut déclencher un événement d’entrée pour cette région.

Android

L’exemple de code suivant illustre la gestion du résultat fourni dans le rappel de getNearbyPointsOfInterest, un List<PlacesPOI>:

void handleUpdatedPOIs(final List<PlacesPOI> nearbyPois) {
    // get the list of regions we know the user is already within from SharedPreferences
    SharedPreferences preferences = getApplicationContext().getSharedPreferences("places", 0);
    Set<String> regionsUserIsAlreadyIn = preferences.getStringSet("regionsUserIsAlreadyIn", new HashSet<String>());

    // loop through new placesPOIS and post entry events for pois that aren't already in our list
    // also create the new list of regions that the user is in
    Set<String> updatedRegionsUserIsIn = new HashSet<String>();
    for (PlacesPOI poi : nearbyPois) {
        // check if the user is in this poi
        if (poi.containsUser()) {
            // the user is in the poi, now we need to make sure we haven't already recorded this entry event
            if (!regionsUserIsAlreadyIn.contains(poi.getIdentifier())) {
                Geofence poiGeofence = new Geofence.Builder()
                    .setRequestId(poi.getIdentifier())
                    .setTransitionTypes(Geofence.GEOFENCE_TRANSITION_ENTER)
                    .setCircularRegion(poi.getLatitude(), poi.getLongitude(), poi.getRadius())
                    .setExpirationDuration(Geofence.NEVER_EXPIRE)
                    .build();
                Places.processGeofence(poiGeofence, Geofence.GEOFENCE_TRANSITION_ENTER);
            }

            // add the region to our new list of regions
            updatedRegionsUserIsIn.add(poi.getIdentifier());
        }
    }

    // update SharedPreferences with our new list of regions
    SharedPreferences.Editor editor = getApplicationContext().getSharedPreferences("places", 0).edit();
    editor.putStringSet("regionsUserIsAlreadyIn", updatedRegionsUserIsIn).apply();
}

Outre le déclenchement des événements d’entrée du service Places dans le SDK, en raison des événements d’entrée de déclenchement, toutes les données qui définissent vos points ciblés peuvent être utilisées par le reste du SDK via data elements dans Experience Platform Launch. Avec Experience Platform Launch rules, vous pouvez joindre dynamiquement les données du service Places aux événements entrants qui sont traités par le SDK. Par exemple, vous pouvez joindre les métadonnées d’un point ciblé dans lequel l’utilisateur se trouve et envoyer les données à Analytics en tant que données contextuelles.
