推荐答案
这可能是因为新BTLE航标技术，如苹果公司的iBeacon显示或谷歌自己的埃迪斯通规范。这些是用于微位服务的工具，并因此可以由应用程序被用来绘制出（相当precisely），你在哪里。考虑到粗，细位置的权限似乎是适当的。
It's likely due to new BTLE beacon technology such as Apple's iBeacon or Google's own Eddystone spec. These are tools used for microlocation services, and as a result can be used by the application to map out (quite precisely) where you are. Considering that, coarse and fine location permissions seem appropriate.
