我尝试通过网络提供商检索服务中的位置更新，但更新没有执行。我的代码如下所示：

public class TimeService extends Service{

LocationManager lm;
LocationListener ll = new LocationListener()
{

    @Override
    public void onLocationChanged(Location location) {

        double latitude = location.getLatitude();
        double longtitude = location.getLongitude();

        Intent inte =new Intent( TimeService.this, myAppWidgetProvider.class);
        inte.setAction("action_location");
        inte.putExtra("lat", latitude);
        inte.putExtra("long", longtitude);

        PendingIntent pinte = PendingIntent.getBroadcast(TimeService.this, 0, inte, 0);

        try {
            pinte.send();
        } catch (CanceledException e) {
            // TODO Auto-generated catch block
            Log.d("sendPIException", ":-(");
        }

        Log.d("locReceived", "onLochanged");

    }

    @Override
    public void onProviderDisabled(String provider) {
        // TODO Auto-generated method stub

    }

    @Override
    public void onProviderEnabled(String provider) {
        // TODO Auto-generated method stub

    }

    @Override
    public void onStatusChanged(String provider, int status,
            Bundle extras) {
        // TODO Auto-generated method stub

    }

};

在 onLocationChanged 中记录“locReceived”没有出现我 logcat 以下代码也负责我的服务中的位置：

@Override
    public int onStartCommand(Intent intent, int flags, int startId) {
        this.registerReceiver(br, new IntentFilter(Intent.ACTION_TIME_TICK));
        lm =(LocationManager)this.getSystemService(Context.LOCATION_SERVICE);
        lm.requestLocationUpdates(LocationManager.NETWORK_PROVIDER, 0, 0, ll);
        return super.onStartCommand(intent, flags, startId);
    }

我的代码有什么问题？

Criteria criteria = new Criteria();

String provider = lm.getBestProvider(criteria, false);
Location location = lm.getLastKnownLocation(provider);

lm.requestLocationUpdates(provider, 0, 0, ll);

if (location == null) {
    Log.e("Impl", "Location not available");
}
