问题描述
我只是在做机器人演示了地理围栏按文档，但这里地质击剑广播接收器并没有叫，当我从围栏面积外出或进入它。
I just made a demo for the Geo Fencing in android as per the documentation but here Geo Fencing Broadcast Receiver is not calling when I go out from the fence area or entered into it.
专家看code和试图抓住这个问题。
Guys look the code and try to catch the issue.

它成功添加地理围栏，但后来它不会调用广播接收器来了解是否进入/退出
It add the Geo Fence successfully but later it does not call the Broadcast receiver to get to know whether entered/exit
推荐答案
Android的地理围栏从未启用GPS（因为它们的API是可怕的和器件的功耗已经是如此不可收拾的地步）。你必须设置你的地理围栏，然后不断的，如果你想在GPS地理围栏分别轮询GPS。
Android GeoFences never enable the GPS (because their API is awful and their device power consumption is already so out of hand). You have to set up your geofences and then constantly poll the GPS separately if you want geofencing over GPS.
