Public Methods

public Task<Void> addGeofences (GeofencingRequest geofencingRequest, PendingIntent pendingIntent)

Sets alerts to be notified when the device enters or exits one of the specified geofences. If an existing geofence with the same request ID is already registered, the old geofence is replaced by the new one, and the new PendingIntent is used to generate intents for alerts.

Task is completed when geofences are successfully added or failed to be added. Upon failure, an ApiException will be set on the Task. Refer to GeofenceStatusCodes for possible errors when adding geofences.

When a geofence transition (for example, entering or exiting) matches one of the transition filter (see setTransitionTypes(int)) in the given geofence list, an intent is generated using the given pending intent. You can call fromIntent(android.content.Intent) to get the transition type, geofences that triggered this intent and the location that triggered the geofence transition.

In case network location provider is disabled by the user, the geofence service will stop updating, all registered geofences will be removed and an intent is generated by the provided pending intent. In this case, the GeofencingEvent created from this intent represents an error event, where hasError() returns true and getErrorCode() returns GEOFENCE_NOT_AVAILABLE.

This method requires ACCESS_FINE_LOCATION.

Parameters

geofencingRequest	geofencing request that include a list of geofences to be added and related triggering behavior. The request must be created using GeofencingRequest.Builder.
pendingIntent	a pending intent that will be used to generate an intent when matched geofence transition is observed

Throws

SecurityException	if the app does not have ACCESS_FINE_LOCATION permission
NullPointerException	if geofencingRequest or pendingIntent is null

public Task<Void> removeGeofences (List<String> geofenceRequestIds)

Removes geofences by their request IDs. Request ID is specified when you create a Geofence by calling setRequestId(String).

Task is completed when geofences are successfully removed or fail to be removed. Upon failure, an ApiException will be set on the Task. Refer to GeofenceStatusCodes for possible errors when removing geofences.

This method requires ACCESS_FINE_LOCATION.

Parameters

geofenceRequestIds	a list of request IDs of geofences that need to be removed

Throws

IllegalArgumentException	if geofenceRequestIds is null or empty
SecurityException	if the app does not have ACCESS_FINE_LOCATION permission
NullPointerException	if listener is null

public Task<Void> removeGeofences (PendingIntent pendingIntent)

Removes all geofences associated with the given pendingIntent.

Warning: equals(Object) is used for comparison. Please use FLAG_UPDATE_CURRENT rather than FLAG_CANCEL_CURRENT when creating the pending intent, otherwise you will not get the same pending intent you provided to addGeofences(GeofencingRequest, PendingIntent) and thus the removal operation will remove nothing.

Task is completed when geofences are successfully removed or fail to be removed. Upon failure, an ApiException will be set on the Task. Refer to GeofenceStatusCodes for possible errors when removing geofences.

This method requires ACCESS_FINE_LOCATION.

Parameters

pendingIntent	the pending intent associated with the geofences that need to be removed.

Throws

SecurityException	if the app does not have ACCESS_FINE_LOCATION permission
NullPointerException	if intent or listener is null
