不使用活动区域监视的Places服务 use-places-without-active-monitoring
应用程序的用例可能不需要主动区域监控。 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来收集设备的位置。
TIP
如果您的应用程序用例需要主动区域监控，请参阅 将Places Service与您自己的监控解决方案结合使用.
要在不使用活动区域监视的情况下使用Places服务，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收集设备的当前位置 CoreLocation.framework (iOS)或 Location 由Google Play Services (Android)提供的API。
有关更多信息，请参阅以下文档：
- 核心位置 (Apple)
- Google Play服务中的位置API (Google)
2.从SDK检索附近的目标点
获取用户的位置后，您可以将其传递到SDK以返回附近POI的列表。
Android
以下是Android中的实施示例，其中使用 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。 代码显示了 locationManager:didUpdateLocations: 中的方法 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。 代码显示了 locationManager(_:didUpdateLocations:) 中的方法 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数据附加到您的Analytics请求
通过调用 getNearbyPointsOfInterest 在API中，Places SDK将通过Launch中的数据元素提供与设备相关的所有POI数据。 通过使用 附加数据 规则，Places数据可以自动添加到未来的Analytics请求中。 这样一来，在收集设备位置时，便无需一次性调用Analytics。
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 — 当用户处于POI中时触发进入事件
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。 如果用户处于POI中，您可以让SDK触发该区域的进入事件。
IMPORTANT
要防止应用程序在一次访问中触发多个进入事件，请保留您知道用户已进入的地区的列表。 处理来自SDK的附近POI的响应时，仅当区域不在您的列表中时才会触发进入事件。
在以下代码示例中，
NSUserDefaults (iOS)及 SharedPreferences (Android)用于管理区域列表：Android
以下代码示例显示了如何处理回调中提供的结果 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如何处理回调中提供的结果 getNearbyPointsOfInterest:limit:callback:errorCallback:，和 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如何处理回调中提供的结果 getNearbyPoints(_ ofInterest: CLLocation, limit: UInt, callback: (([ACPPlacesPoi]?) -> Void)?, errorCallback: ((ACPPlacesRequestError) -> Void)?)，和 [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")
}

除了在SDK中触发Places Service进入事件外，由于触发了进入事件，因此SDK的其余部分也可以使用定义目标点的所有数据，途径为 data elements Experience Platform Launch中。 带有Experience Platform Launch rules，您可以将Places服务数据动态附加到SDK处理的传入事件。 例如，您可以附加用户所在的POI的元数据，然后将该数据作为上下文数据发送到Analytics。
