有多少准确度不PRIORITY_BALANCED_POWER_ACCURACY给？ [英] How much accuracy does PRIORITY_BALANCED_POWER_ACCURACY give?

问题描述

我希望收到具有一定精度在一个城市，这意味着approximatelly 50米200米的精度范围将是合理的跟踪摩托车驾驶员位置更新。我怎么这个映射到setPriority（）的参数？换句话说，考虑到目前位置服务的实施和一些组设备（定义它们？）做这个地图PRIORITY_BALANCED_POWER_ACCURACY或PRIORITY_HIGH_ACCURACY？的

I'd like to receive location updates with a certain accuracy for tracking motorcycle riders in a city, which means that an accuracy range of approximatelly 50m to 200m would be reasonable. How do I map this to the setPriority() parameter ? In other words, given current location services implementation and some set of devices (define them ?) does this map to PRIORITY_BALANCED_POWER_ACCURACY or to PRIORITY_HIGH_ACCURACY ?

推荐答案

有关50m-200米ACCURAY你需要GPS所有的时间。结果
没有半功率GPS，让利locationg工艺来实现这一目标的精度。
（手机信号塔1000米和WLAN斑点50米如果你有一个，但往往是没有的。）

For 50m- 200m accuray you need GPS all the time.
There is no half power GPS, none of other locationg technics achieve this accuracy. (Cell Tower 1000m, and Wlan spots 50m if you have one, but often there is none.)

如果应用必须跟踪他们，你必须使用GPS_PROVIDER

If the app has to track them, you have to use GPS_PROVIDER
