如何停止位置管理器? [英] How to stop location manager?

问题描述

不知道为什么，但是有时位置管理器在关闭应用程序后仍然可以正常工作.

Don't know why, but sometimes LocationManager is still working also after closing application.

我在一个Activity中的onCreate-Methode中调用startGPS()(只有一个，我称之为StartActivity).

I call startGPS() in onCreate-Methode in one Activity (only one, let me call it StartActivity).

protected void startGPS(){    
 try {           
     lmanager = (LocationManager)getSystemService(Context.LOCATION_SERVICE);
     lmanager.requestLocationUpdates(LocationManager.NETWORK_PROVIDER, 0, 0, this);
     lmanager.requestLocationUpdates(LocationManager.GPS_PROVIDER, 0, 0, this);
 } catch(Exception e) {
     e.printStackTrace();
 }
}

如果此活动将被破坏(因此，当应用程序关闭时)，我将调用endGPS()

And if this activity will be destroyed (so, when application will be closed), I call endGPS()

public void endGPS(){
 try {           
     lmanager.removeUpdates(this);
     lmanager=null;
 } catch(Exception e) {
  e.printStackTrace();
 }
}

一些想法，一些建议，我做错了什么?！

Some ideas, some suggestions, what have I done wrong?!

推荐答案

是否可能没有破坏您的活动?即:您按下了主页按钮.将您的GPS起点/终点移至onStart和onPause.

Is it possible your activity isn't being destroyed? i.e.: you hit the home button. Move your gps start/stop to onStart and onPause.
