我有一个singelton线程类，它将gps指向我的服务器。该类保持并刷新gps位置。
FinderThread：
public class FinderThread extends Thread {

public boolean isinterrupt = true;

public int minage;
public int distance;

private Handler dlh;
private Handler myLocationHandler;
boolean pause=false;
private FinderThread(Context ctx,Handler dlh, Handler myLocationHandler) {
this.ctx = ctx;
gps = (LocationManager) ctx.getSystemService(Context.LOCATION_SERVICE);
gps.requestLocationUpdates( LocationManager.GPS_PROVIDER,60000, 20, llistener);
pref = ctx.getSharedPreferences("NFF", 0);
sid = pref.getString("sid", "");
this.dlh = dlh;
if (myLocationHandler!=null)
{
this.myLocationHandler = myLocationHandler;
}
if(myLocationHandler != null)
{
myLocationHandler.sendEmptyMessage(0);
}
}
public static synchronized FinderThread getInstance(Context ctx,Handler dlh, Handler myLocationHandler)

当我在模拟器上测试我的应用程序并使用模拟器控件设置位置时，everthing工作正常。当我在手机上测试时，机器人找不到位置。我已经测试了应用程序“GPS测试”，它在3分钟内找到了5个卫星的位置。
请帮忙

看起来你在那里拥有一切。
你在FINE_LOCATION的清单中给自己一个权限，对吗？
我要提出的一个建议就是更改你的requestLocationUpdates()，以便它们要求修复它们之间的0时间和0之间的距离。我见过的所有GPS接收器都会通过此设置为您提供大约每秒一次的修复，这几乎是大多数GPS引擎的工作方式。只是在您提出请求的一分钟和20米的可能性让您失望。如果你得到了这个建议的修复，你可以在那里工作，以尽量减少gps的开启时间。
