我通过该警报管理器拥有警报管理器，我正在启动一项服务，但是当我停止该警报管理器时，该服务的 onDestroy 方法永远不会被调用。

我的代码：

启动服务

            //----------------------------------------------------------------------------------------
            //Starting Alarm Manager for Lat Lng
            //----------------------------------------------------------------------------------------

            AlarmManager alarmManager = (AlarmManager)getSystemService(ALARM_SERVICE);

            Calendar calendar = Calendar.getInstance();
            calendar.setTimeInMillis(System.currentTimeMillis());
            calendar.add(Calendar.SECOND, 10);
            alarmManager.setRepeating(AlarmManager.RTC_WAKEUP, calendar.getTimeInMillis(), 1000*1, pendingIntent);

            //----------------------------------------------------------------------------------------
            //Starting Alarm Manager for Lat Lng
            //----------------------------------------------------------------------------------------

停止服务

AlarmManager alarmManager = (AlarmManager)getSystemService(ALARM_SERVICE);
alarmManager.cancel(pendingIntent);

我的服务

double nlat;
double nlng;
double glat;
double glng;

LocationManager glocManager;

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

@Override

    LocationManager nlocManager   = (LocationManager)getSystemService(Context.LOCATION_SERVICE);
    LocationListener nlocListener = new MyLocationListenerNetWork();
    nlocManager.requestLocationUpdates(LocationManager.NETWORK_PROVIDER,
            1,          
            1,

AlarmManager alarmManager = (AlarmManager)getSystemService(ALARM_SERVICE);
alarmManager.cancel(pendingIntent);

您只是取消了alarmManager，这意味着警报管理器不会再次启动该服务。

要停止服务：

stopService(new Intent(this, YourService.class));
