cl.location.1 位置服务权限变更

从API9开始，增加ohos.permission.APPROXIMATELY_LOCATION，表示模糊位置权限。

如果应用开发者使用的API版本大于等于9，则需要同时申请ohos.permission.LOCATION和ohos.permission.APPROXIMATELY_LOCATION，单独申请ohos.permission.LOCATION会失败。

变更影响

如果是存量应用（使用的API版本小于9），则无影响。如果使用的API版本大于等于9，位置服务权限申请方式有变更，详情如下：

应用在使用系统能力前，需要检查是否已经获取用户授权访问设备位置信息。如未获得授权，可以向用户申请需要的位置权限，申请方式请参考下文。

系统提供的定位权限有：

• ohos.permission.LOCATION

• ohos.permission.APPROXIMATELY_LOCATION

• ohos.permission.LOCATION_IN_BACKGROUND

访问设备的位置信息，必须申请权限，并且获得用户授权。

API9之前的版本，申请ohos.permission.LOCATION即可。

API9及之后的版本，需要申请ohos.permission.APPROXIMATELY_LOCATION或者同时申请ohos.permission.APPROXIMATELY_LOCATION和ohos.permission.LOCATION；无法单独申请ohos.permission.LOCATION。

如果应用在后台运行时也需要访问设备位置，除需要将应用声明为允许后台运行外，还必须申请ohos.permission.LOCATION_IN_BACKGROUND权限，这样应用在切入后台之后，系统可以继续上报位置信息。

开发者可以在应用配置文件中声明所需要的权限，具体可参考授权申请指导。
