    If your application needs to access the device location information when running on the background, it must be configured to be able to run on 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.
 
-   To allow your application to access device location information, declare the required permissions in the **module.json** file of your application. The sample code is as follows:
-
-   
-   ```
-   {
-       "module": {
-           "reqPermissions": [
-               "name": "ohos.permission.LOCATION",

-               }
-           ]
-       }
-   }

-   For details about these fields, see [Application Package Structure Configuration File](../quick-start/stage-structure.md).
+   You can declare the required permission in your application's configuration file. For details, see [Access Control (Permission) Development](../security/accesstoken-guidelines.md).
 
 2. Import the **geolocation** module by which you can implement all APIs related to the basic location capabilities.
