# Access Token Changelog
## cl.access_token.1 Behavior Change When Location Permission Is Requested by requestPermissionsFromUser

**Access Level**

Public

**Reason for Change**

According to privacy protection requirements, the location permission is added with the **Allow only while in use** option, and the **ohos.permission.LOCATION_IN_BACKGROUND** permission cannot be granted separately in a dialog box.

If an application requires **ohos.permission.LOCATION_IN_BACKGROUND**, the permission must be granted by the user in **Settings**. For details, see **Adaptation Guide**.

**Change Impact**

Involved permissions:

- Foreground location permissions (used to control the behavior of a foreground application to obtain location information):
  - [ohos.permission.LOCATION](../../../application-dev/security/AccessToken/permissions-for-all.md#ohospermissionlocation): allows an application to obtain the precise location information of a device. This permission can be requested only after the ohos.permission.APPROXIMATELY_LOCATION permission is available.
  - [ohos.permission.APPROXIMATELY_LOCATION](../../../application-dev/security/AccessToken/permissions-for-all.md#ohospermissionapproximately_location): allows an application to obtain approximate location information of a device.

- Background location permission (used to control the behavior of a background application to obtain location information):

  [ohos.permission.LOCATION_IN_BACKGROUND](../../../application-dev/security/AccessToken/permissions-for-all.md#ohospermissionlocation_in_background): allows an application running in the background to obtain device location information. This permission can be requested only after the foreground location permissions are available.

The following scenarios are involved:

a) The application requests only the background location permission (without the foreground location permissions).

Before the change:<br>A dialog box will be displayed for granting the **ohos.permission.LOCATION_IN_BACKGROUND** permission.

After the change:<br>The **ohos.permission.LOCATION_IN_BACKGROUND** permission cannot be granted by the user in a dialog box.

b) The application requests only the background location permission (with the foreground location permissions available).

Before the change:<br>The **ohos.permission.LOCATION_IN_BACKGROUND** permission is granted when the **ohos.permission.LOCATION** permission is granted for the first time.

After the change:<br>The **ohos.permission.LOCATION_IN_BACKGROUND** permission cannot be granted by the user in a dialog box.

c) The application requests both the foreground and background location permissions.

Before the change:<br>A dialog box containing **Allow** and **Deny** will be displayed for granting the permissions.

After the change:

API 10 and earlier: A dialog box containing **Allow only while in use** and **Deny** will be displayed. If **Allow only while in use** is selected, only the **ohos.permission.LOCATION** permission is granted.

API 11 and later: No dialog box will be displayed for granting the foreground and background location permissions.

**Adaptation Guide**

1. Request the foreground and background location permissions for your application using **requestPermissionsFromUser**.

    a) Check whether the application requires the background location permission. If yes, request the foreground location permissions first.

        Change:
        atManager.requestPermissionsFromUser(context, ['ohos.permission.APPROXIMATELY_LOCATION', 'ohos.permission.LOCATION', 'ohos.permission.LOCATION_IN_BACKGROUND'], ......)
        To:
        atManager.requestPermissionsFromUser(context, ['ohos.permission.APPROXIMATELY_LOCATION', 'ohos.permission.LOCATION'], ......)
        
        Or change:
        atManager.requestPermissionsFromUser(context, ['ohos.permission.APPROXIMATELY_LOCATION', 'ohos.permission.LOCATION_IN_BACKGROUND'], ......)
        To:
        <br>atManager.requestPermissionsFromUser(context, ['ohos.permission.APPROXIMATELY_LOCATION'], ......).

    b) After the user has granted the foreground location permissions, a dialog box is displayed, informing the user to grant the background location permission in **Settings**.

    c) The user selects **Always allow** on the **Settings** screen to grant the background location permission.

2. Request only the background location permission for your application using **requestPermissionsFromUser**.

    a) Check whether the application requires the background location permission. If yes, request the foreground location permissions in a dialog box first.

        Change:
        atManager.requestPermissionsFromUser(context, ['ohos.permission.LOCATION_IN_BACKGROUND'], ......)
    To:
        atManager.requestPermissionsFromUser(context, ['ohos.permission.APPROXIMATELY_LOCATION', 'ohos.permission.LOCATION'], ......)
        
    Or change:
        atManager.requestPermissionsFromUser(context, ['ohos.permission.LOCATION_IN_BACKGROUND'], ......)
        To:
        atManager.requestPermissionsFromUser(context, ['ohos.permission.APPROXIMATELY_LOCATION'], ......).
    
    b) See the steps in case 1.
