Location Subsystem Changelog
cl.location.1 API Migration from @system.geolocation.d.ts to @ohos.geoLocationManager.d.ts
APIs in @system.geolocation.d.ts do not support throwing error codes. To support this function, all APIs in @system.geolocation.d.ts are migrated to the newly added @ohos.geoLocationManager.d.ts file, and corresponding error code description is added.
To use APIs of the location subsystem, you need to import @ohos.geoLocationManager.
import geoLocationManager from ‘@ohos.geoLocationManager’;
Change Impact
All APIs of the location subsystem are affected. To ensure normal use of these APIs, you need to import @ohos.geoLocationManager.
import geoLocationManager from ‘@ohos.geoLocationManager’;
