使用Places Service，而不进行活动区域监控

您的应用程序的用例可能不需要进行活动区域监控。 Places Service仍可用于将用户的位置数据与其他Experience Platform产品集成。

先决条件

开发人员将使用目标平台操作系统提供的API收集设备的位置。

小贴士

如果您的应用程序用例需要活动区域监控，请参阅将Places Service与您自己的监控解决方案结合使用.

要使用Places Service，而不进行活动区域监控，请执行以下操作：

1.收集用户的位置

应用程序开发人员必须使用 CoreLocation.framework (iOS)或 Location 由Google Play服务(Android)提供的API。

有关更多信息，请参阅以下文档：

CoreLocation (Apple)
Google Play服务中的位置API (Google)

2.从SDK中检索附近的目标点

获取用户位置后，可以将其传递到SDK，以返回附近POI的列表。

Android

以下是Android中使用 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

以下是iOS的实施示例。该代码显示了 locationManager:didUpdateLocations: 方法 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

以下是iOS的实施示例。该代码显示了 locationManager(_:didUpdateLocations:) 方法 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.将Places数据附加到Analytics请求

通过调用 getNearbyPointsOfInterest API中，Places SDK将通过Launch中的数据元素，使与设备相关的所有POI数据都可用。通过使用附加数据规则中，可以将Places数据自动添加到将来对Analytics的请求中。这样，在收集设备位置时便无需对Analytics进行一次性调用。

请参阅将位置上下文添加到Analytics请求以了解有关此主题的更多信息。

可选 — 当用户位于POI中时触发登入事件

小贴士

捕获Places数据的推荐方法是将Places数据附加到Analytics请求.

如果用例需要区域登入事件要由SDK触发，需要手动完成，如下所述。

返回的列表 getNearbyPointsOfInterest API包含自定义对象指示用户当前是否在POI内。如果用户在POI中，您可以让SDK触发该区域的登入事件。

重要

要防止您的应用程序在一次访问中触发多个条目事件，请保留您知道用户在哪些地区进入的列表。在处理来自SDK的附近POI的响应时，仅当该区域不在您的列表中时，才会触发登入事件。

在以下代码示例中， NSUserDefaults (iOS和 SharedPreferences (Android)用于管理区域列表：

Android

以下代码示例显示了对的回调中提供的结果的处理 getNearbyPointsOfInterest, a 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();
}

Objective-C

以下代码示例显示了对的回调中提供的结果的处理 getNearbyPointsOfInterest:limit:callback:errorCallback:, NSArray<ACPPlacesPoi *> *:

- (void) handleUpdatedPOIs:(NSArray<ACPPlacesPoi *> *)nearbyPois {
   // get the list of regions we know the user is already within from user defaults
   NSArray *regionsUserIsCurrentlyWithin = [[NSUserDefaults standardUserDefaults]
                                            arrayForKey:@"regionsUserIsAlreadyIn"];

   // loop through new nearbyPoi and post entry events for pois that aren't already in our list
   // also creating the new list of known regions that the user is in
   NSMutableArray *updatedRegionsUserIsCurrentlyWithin = [@[] mutableCopy];
   for (ACPPlacesPoi *poi in nearbyPois) {
       // check if the user is in this poi
       if (poi.userIsWithin) {
           // the user is in the poi, now we need to make sure we haven't already recorded the entry event
           if (![regionsUserIsCurrentlyWithin containsObject:poi.identifier]) {
               CLCircularRegion *region = [[CLCircularRegion alloc] initWithCenter:CLLocationCoordinate2DMake(poi.latitude, poi.longitude)
                                                                            radius:poi.radius
                                                                        identifier:poi.identifier];
               [ACPPlaces processRegionEvent:region forRegionEventType:ACPRegionEventTypeEntry];
           }

           // add the region to our updated list
           [updatedRegionsUserIsCurrentlyWithin addObject:poi.identifier];
       }
   }

   // update user defaults with the new list
   [[NSUserDefaults standardUserDefaults] setObject:updatedRegionsUserIsCurrentlyWithin forKey:@"regionsUserIsAlreadyIn"];
}

Swift

以下代码示例显示了对的回调中提供的结果的处理 getNearbyPoints(_ ofInterest: CLLocation, limit: UInt, callback: (([ACPPlacesPoi]?) -> Void)?, errorCallback: ((ACPPlacesRequestError) -> Void)?), [ACPPlacesPoi]:

func handleUpdatedPOIs(_ nearbyPois:[ACPPlacesPoi]) {
    // get the list of regions we know the user is already within from user defaults
    let regionsUserIsCurrentlyWithin : [String] = UserDefaults.standard.array(forKey: "regionsUserIsAlreadyIn") as! [String]

    // loop through new nearbyPoi and post entry events for pois that aren't already in our list
    // also creating the new list of known regions that the user is in
    var updatedRegionsUserIsCurrentlyWithin: [String] = []
    for poi in nearbyPois {
        // check if the user is in this poi
        if poi.userIsWithin {
            // the user is in the poi, now we need to make sure we haven't already recorded the entry event
            if !regionsUserIsCurrentlyWithin.contains(poi.identifier!) {
                let region = CLCircularRegion.init(center: CLLocationCoordinate2D.init(latitude: poi.latitude, longitude: poi.longitude), radius: CLLocationDistance(poi.radius), identifier: poi.identifier!)
                ACPPlaces.processRegionEvent(region, for: .entry)
            }

            // add the region to our updated list
            updatedRegionsUserIsCurrentlyWithin.append(poi.identifier!)
        }
    }

    // update user defaults with the new list
    UserDefaults.standard.set(updatedRegionsUserIsCurrentlyWithin, forKey: "regionsUserIsAlreadyIn")
}

完成实施示例

以下代码示例向您展示了如何检索设备的当前位置、触发必要的登入事件，以及确保在一次访问中不会获得同一位置的多个条目。

此代码示例包含的可选步骤为当用户位于POI中时触发条目事件.

重要

这些片段是仅示例。开发人员必须确定要如何实施该功能，并且决策时应考虑目标操作系统建议的最佳实践。
