This Location Manager API provides functions for obtaining information related to geographical location. This API provides functions to acquire information related to the current position. Notifications on events like service becoming enabled or disabled, new position data being available and others can also be acquired.

Required Header

#include <locations.h>

Overview

The Location Manager API provides functions to acquire information about geographical location, including both as accurate a current position as possible, and receiving notification of changes in position, crossing boundary "fences", and velocity changes detected by the device. The related Geolocation API can be used to convert the location to a physical address. Notifications can be received about the following events:

Change in service status (enabled / disabled)
New position and velocity information becoming available
Given area being entered or left (geofencing) Information on GPS satellites is provided by the GPS Status & Satellite API. The main component of the Location Service is the location manager. A location manager serves as a gateway, so the application does not have to manage the details of the back-end connection, which might be GPS, WiFi or others, although it may instruct the location manager as to a preference. The location manager also manages the callback functions which it invokes when a given event takes place. The location manager has the following properties:
Method
Boundary
'Position updated' callback
'Service state change' callback
'Velocity updated' callback
'Boundary event' callback The method property of a location manager (location_method_e) determines the source of location information. It can be set only once - when the location manager is instantiated. The method can be one specific location method, or hybrid. A location manager set to the hybrid method will automatically choose the best method available at the moment, choosing between GPS, WPS and WPS. Note that the method may change any time, due to signals coming in/out of range, and so on. If more than one method is available, priorities are as follows: 1. GPS
2. WPS
If no methods are available, the service state is changed to disabled and the appropriate callback is called. See location_manager_set_service_state_changed_cb() and location_service_state_changed_cb(). The boundary property describes a border enclosing an area. The area can be circular - defined by its center in geographic coordinates a radius, or rectangular - defined by the geographic coordinates of its top-left and bottom-right corner. The location manager will use the selected method to track if the area has been entered or exited. The location manager will send asynchronous notifications by invoking previously registered callback functions on such change events. There may be multiple location managers. Callback functions to receive notifications are registered to a specific location manager, not to the location service as a whole. So it is, for example, possible to define several different geographic areas or fences, using different location methods, each being tracked by a different location manager and leading to distinct callbacks. Setting and unsetting callbacks for the manager can be done at any time, however before callbacks set for a given location manager can be invoked, the location service must be started for that location manager. This constraint holds for managers with GPS, WPS, and Hybrid methods. See the Location manager life cycle section below. Note the start/stop functions apply only to the individual location manager and do not affect any other location managers that may be running. Only one callback can be set for a given event within the scope of a single location manager. Successive callback setting will result in the new callback replacing the old one. If an 'unset callback' function is called when there is no callback set, no error is returned. Callbacks can be set and unset any number of times.

Location manager life cycle

1. Create location manager ( location_manager_create() )
2. Set callbacks and other required information
3. Start service with location_manager_start()
4. Wait until state change callback ( location_service_state_changed_cb() ) is called with LOCATIONS_SERVICE_ENABLED as first argument
5. Other callbacks are working now, wait for events and process
6. Stop service with location_manager_stop()
7. Wait until state change callback ( location_service_state_changed_cb() ) is called with LOCATIONS_SERVICE_DISABLED as first argument
8. Destroy location manager ( location_manager_destroy() )
After stopping the location service for a given location manager, the location manager can still be used. So some functions can be called if they do not require a location service running on your device. The location service can be re-started later. If a location manager is no longer needed and is going to be destroyed, it is not mandatory to call location_manager_stop(), as location_manager_destroy() will call it automatically. Note that after a location manager has been destroyed, the handle (location_manager_h) can be reused - location_manager_create() can be called again for this handle. In other words, the state before creation and after destruction can be treated as the same state.
