Geo-triggering

Start Geo-triggering

Geo-triggering allows the automatic detection of location context change events (such as entering or exiting a geofence, or crossing a Geoline™). For this capability, the SDK needs to be initialized and the app must have location permission. For many use cases, a foreground service notification is also recommended.

To start geo-triggering, you should create and start the GeoTriggeringService as below:

if (ServiceManager.getInstance(context).isBluedotServiceInitialized()) {
    // The Bluedot SDK is initialized, you can start Geo-triggering.

    GeoTriggeringService.builder()
            .notification(notificationReference) // Notification to use to run Geo-triggering as a foreground service.
            .notificationId(myNotificationId) // Optional id to use for foreground service notification.  Use if your app will // run additional foreground services, or you wish to update the notification.
            .start(myApplicationContext, // This context should be the Application context.
                   error -> {
                       if (error != null) {
                           // Something went wrong when starting Geo-triggering. Handle error here.
                           return;
                       }
                       // Geo-triggering has started successfully. Handle success here.
                   });
} else {
    // The Bluedot SDK is not initialized. Initialize before starting Geo-triggering.
}

Receiving Geo-trigger events

Create a receiver in the Manifest to receive geo-trigger events (such as entering a location):

AndroidManifest

<application android:label="@string/app_name" >
     <receiver
        android:name="my.package.ExampleGeoTriggerReceiver"
        android:enabled="true"
        android:exported="false"
     >
        <intent-filter>
           <action android:name="io.bluedot.point.GEOTRIGGER" />
        </intent-filter>
     </receiver>
 </application>

class ExampleGeoTriggerReceiver : GeoTriggeringEventReceiver() {
    override fun onZoneInfoUpdate(zones: List<ZoneInfo>, context: Context) {
        // Notification that the local cache of zones has been updated.
     }
 
    override fun onZoneEntryEvent(entryEvent: ZoneEntryEvent, context: Context) {
        // Notification that a zone has been entered/Geoline™ crossed.
     }
 
     override fun onZoneExitEvent(exitEvent: ZoneExitEvent, context: Context) {
        // Notification that an exit detection-enabled zone has been exited.
     }   
 }

Stop Geo-triggering

If you only need geo-triggering for a limited period, once that period is over, you can stop the geo-trigger service.

GeoTriggeringService.stop(myContext, error -> { 
    if (error != null) {
        // Something went wrong stopping Geo-triggering. Handle error here.
        return;
    }
    
    // Geo-triggering stopped successfully. Handle success here.
});

Geo-triggering start and stop status are provided through callbacks on the  geoTriggeringStatusListener, implemented as lambda functions in the above examples.
