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 Impacts

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’;

(Optional) Adaptation Guide

The following sample code shows how to call enableLocation in the new version:

  import geoLocationManager from '@ohos.geoLocationManager';
  try {
      geoLocationManager.enableLocation((err, data) => {
          if (err) {
              console.log('enableLocation: err=' + JSON.stringify(err));
          }
      });
  } catch (err) {
      console.error("errCode:" + err.code + ",errMessage:" + err.message);
  }
