Android服务刷新位置

Question

我有一个从api获取数据的服务。我想实现一个位置管理器，这样我就可以获得用户位置并更新lat和lng。 我有这个每分钟刷新一次的服务，并通过调用LoadPlaces（它创建一个对象）从API加载数据。所以我想得到用户的lat和lng并将其传递给对象。 代码如下。有帮助吗？ 感谢

public class DownloadPlaceService extends Service {
Double lat, lng;

public DownloadPlaceService() {

}

private static final String TAG = "TAG";
private LocationManager mLocationManager = null;
private static final int LOCATION_INTERVAL = 400;
protected LocationManager locationManager;
protected LocationListener locationListener;

@Override
public void onCreate() {
    super.onCreate();
    Log.i("StartCommand", "started");
    lat = 42.01;
    lng = 21.22;

}


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

        //locationManager.requestLocationUpdates("gps", 0, 0, locationListener);


    final Context context = this;

    Log.w("Coordinates",lat+"");

    LoadPlaces reloadPersons = new LoadPlaces(
            this,
            new onDownloadPlaceDatabaseNotification(this),
            lat,
            lng
    );
    reloadPersons.execute();
    Log.i("StartCommand","reloaded persons");
    return super.onStartCommand(intent, flags, startId);
}
@Override
public IBinder onBind(Intent intent) {

    // TODO: Return the communication channel to the service.
    throw new UnsupportedOperationException("Not yet implemented");
}

}
