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",
"reason": "$string:reason_description",
"usedScene": {
"ability": ["com.myapplication.LocationAbility"],
"when": "inuse"
}
