# Location Subsystem ChangeLog

## cl.location.1 API Migration from @ohos.geolocation.d.ts to @ohos.geoLocationManager.d.ts

APIs in **@ohos.geolocation.d.ts** do not support throwing error codes. To support this function, all APIs in **@ohos.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:

  ```ts
  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);
  }
  ```
