无法停止LocationListener服务

Question

在Splash Activity的onResume()中，我以这种方式启动服务。

AlarmManager am = (AlarmManager) getSystemService(ALARM_SERVICE);
Intent i = new Intent(this, LocationService.class);
PendingIntent pi = PendingIntent.getService(this, 0, i,
            PendingIntent.FLAG_UPDATE_CURRENT);
am.cancel(pi);
am.setInexactRepeating(AlarmManager.ELAPSED_REALTIME_WAKEUP,
                        ystemClock.elapsedRealtime() + 20000, 60000, pi);

在onStop()中，我以这种方式停止服务

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

服务类是：

public class LocationService extends Service implements LocationListener {

    private LocationManager mgr;

    @Override
    public IBinder onBind(Intent arg0) {

        return null;
    }

    @Override
    public int onStartCommand(Intent intent, int flags, int startId) {

        mgr = (LocationManager) getSystemService(LOCATION_SERVICE);
        //get Location details
        mgr.requestLocationUpdates(LocationManager.GPS_PROVIDER,
                10 * 60 * 1000, 50, this);

        return START_NOT_STICKY;

    }

    private void dumpLocation(Location l) {
    }

    @Override
    public void onLocationChanged(Location location) {
    }

    @Override
    public void onProviderDisabled(String provider) {
    }

    @Override
    public void onProviderEnabled(String provider) {
    }

    @Override
    public void onStatusChanged(String provider, int status, Bundle extras) {
    }

    @Override
    public void onDestroy() {

        super.onDestroy();
        mgr.removeUpdates(this);
    }
}

一旦我在Splash Activity的onStop()中停止了服务，就会触发LocationService的onDestroy() (这意味着服务被停止了？)，但按照AlarmManager中的指定，该服务在一分钟后仍在运行。

将警报的挂起意图存储在变量中。当服务结束时请取消它。
