onLocationChanged（）未在我的服务中执行

Question

我试图自动更新我的位置，并在位置发生更改时使云的相关代码的其他部分工作。这里是我服务的代码：

    @Override 
    public IBinder onBind(Intent arg0) { 
     // TODO Auto-generated method stub 
     return null; 
    } 
} 

祝酒词，直到“里面detectLocation”被弹出，甚至登录取得直到

04-04 00:42:34.687: V/X(10217): Response:After lm1.requestLocationUpdates 

但除此之外，该代码只是可达条目... GPS标志显示在操作栏中，但显示位置的吐司没有弹出...请帮助.... !!!

Answer 1

在requestLocationUpdates(LocationManager.GPS_PROVIDER, 10, Two_Min, ll1)中，您将Two_Min（已设置为5 * 60 * 1000 = 300000）传递到minDistance参数中，该参数应该是米的数量。尝试将minDistance设置为0。
