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。
使用的API版本 | 申请位置权限 | 申请结果 | 位置的精确度 |
---|---|---|---|
小于9 | ohos.permission.LOCATION | 成功 | 获取到精准位置,精准度在米级别。 |
大于等于9 | ohos.permission.LOCATION | 失败 | 无法获取位置。 |
大于等于9 | ohos.permission.APPROXIMATELY_LOCATION | 成功 | 获取到模糊位置,精确度为5公里。 |
大于等于9 | ohos.permission.APPROXIMATELY_LOCATION和ohos.permission.LOCATION | 成功 | 获取到精准位置,精准度在米级别。 |
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。
