@ohos.geolocation (Geolocation)

The geolocation module provides a wide array of location services, including GNSS positioning, network positioning, geocoding, reverse geocoding, and geofencing.

NOTE The initial APIs of this module are supported since API version 7. Newly added APIs will be marked with a superscript to indicate their earliest API version. The APIs provided by this module are no longer maintained since API version 9. You are advised to use geoLocationManager.

Applying for Permissions

Before using basic location capabilities, check whether your application has been granted the permission to access the device location information. If not, your application needs to obtain the permission from the user as described below.

The system provides the following location permissions: - ohos.permission.LOCATION

ohos.permission.APPROXIMATELY_LOCATION
ohos.permission.LOCATION_IN_BACKGROUND

If your application needs to access the device location information, it must first apply for required permissions. Specifically speaking:

API versions earlier than 9: Apply for ohos.permission.LOCATION.

API version 9 and later: Apply for ohos.permission.APPROXIMATELY_LOCATION, or apply for ohos.permission.APPROXIMATELY_LOCATION and ohos.permission.LOCATION. Note that ohos.permission.LOCATION cannot be applied for separately.

API Version	Location Permission	Permission Application Result	Location Accuracy
Earlier than 9	ohos.permission.LOCATION	Successful	Location accurate to meters.
9 and later	ohos.permission.LOCATION	Failed	No location obtained.
9 and later	ohos.permission.APPROXIMATELY_LOCATION	Successful	Location accurate to 5 kilometers.
9 and later	ohos.permission.APPROXIMATELY_LOCATION and ohos.permission.LOCATION	Successful	Location accurate to meters.

If your application needs to access the device location information when running in the background, it must be configured to be able to run in the background and be granted the ohos.permission.LOCATION_IN_BACKGROUND permission. In this way, the system continues to report device location information after your application moves to the background.

You can declare the required permission in your application’s configuration file. For details, see Access Control (Permission) Development.

System capability: SystemCapability.Location.Location.Core

Name	Value	Description
UNSET	0x200	Priority unspecified. If this option is used, LocationRequestPriority is invalid.
ACCURACY	0x201	Location accuracy preferred. This policy mainly uses the GNSS positioning technology. In an open area, the technology can achieve the meter-level location accuracy, depending on the hardware performance of the device. However, in a shielded environment, the location accuracy may significantly decrease.
LOW_POWER	0x202	Power efficiency preferred. This policy mainly uses the base station positioning, WLAN positioning, and Bluetooth positioning technologies to obtain device location in both indoor and outdoor scenarios. The location accuracy depends on the distribution of surrounding base stations, visible WLANs, and Bluetooth devices and therefore may fluctuate greatly. This policy is recommended and can reduce power consumption when your application does not require high location accuracy or when base stations, visible WLANs, and Bluetooth devices are densely distributed.
FIRST_FIX	0x203	Fast location preferred. Use this option if you want to obtain a location as fast as possible. This policy uses the GNSS positioning, base station positioning, WLAN positioning, and Bluetooth positioning technologies simultaneously to obtain the device location in both the indoor and outdoor scenarios. When all positioning technologies provide a location result, the system provides the most accurate location result for your application. It can lead to significant hardware resource consumption and power consumption.

LocationRequestScenario^(deprecated)

Sets the scenario of the location request.

NOTE
This API is deprecated since API version 9. You are advised to use geoLocationManager.LocationRequestScenario.

Required permissions: ohos.permission.LOCATION

System capability: SystemCapability.Location.Location.Core

Name	Value	Description
UNSET	0x300	Scenario unspecified. If this option is used, LocationRequestScenario is invalid.
NAVIGATION	0x301	Navigation scenario. This option is applicable when your application needs to obtain the real-time location of a mobile device outdoors, such as navigation for driving or walking. In this scenario, GNSS positioning is used to provide location services to ensure the optimal location accuracy of the system. The location result is reported at a minimum interval of 1 second by default.
TRAJECTORY_TRACKING	0x302	Trajectory tracking scenario. This option is applicable when your application needs to record user trajectories, for example, the track recording function of sports applications. In this scenario, the GNSS positioning technology is mainly used to ensure the location accuracy. The location result is reported at a minimum interval of 1 second by default.
CAR_HAILING	0x303	Ride hailing scenario. This option is applicable when your application needs to obtain the current location of a user who is hailing a taxi. The location result is reported at a minimum interval of 1 second by default.
DAILY_LIFE_SERVICE	0x304	Daily life service scenario. This option is applicable when your application only needs the approximate user location for recommendations and push notifications in scenarios such as when the user is browsing news, shopping online, and ordering food. The location result is reported at a minimum interval of 1 second by default.
NO_POWER	0x305	Power efficiency scenario. This option is applicable when your application does not proactively start the location service. When responding to another application requesting the same location service, the system marks a copy of the location result to your application. In this way, your application will not consume extra power for obtaining the user location.

GeoLocationErrorCode^(deprecated)

Enumerates error codes of the location service.

NOTE
This API is deprecated since API version 9. You are advised to use geoLocationManager.

Required permissions: ohos.permission.LOCATION

LOCATOR_ERROR⁷⁺	104	Failed to obtain the location.
LOCATION_SWITCH_ERROR⁷⁺	105	Failed to change the location service switch.
LAST_KNOWN_LOCATION_ERROR⁷⁺	106	Failed to obtain the previous location.
LOCATION_REQUEST_TIMEOUT_ERROR⁷⁺	107	Failed to obtain the location within the specified time.
