Question

我遇到了这个问题。我有活动和服务我需要该服务为活动提供gps位置

我的服务类，

public class RecordingService extends Service {

public Thread backgroundWork;
public boolean threadCanRun;
private GPSReceiver _gps;

public void onCreate() {
    super.onCreate();
    threadCanRun = true;
    backgroundWork = new Thread(new Runnable() {
        @Override
        public void run() {
            someTask();

        }
    });

}

public int onStartCommand(Intent intent, int flags, int startId) {
    backgroundWork.start();

    return super.onStartCommand(intent, flags, startId);
}

public void onDestroy() {
    threadCanRun = false;
    super.onDestroy();

}

public IBinder onBind(Intent intent) {

    return null;
}

void someTask() {

    while (threadCanRun) {
        Intent intent = new Intent(RecordingActivity.BROADCAST_ACTION);

        _gps = new GPSReceiver(this);

        // preluare status GPS
        LocationManager myManager = (LocationManager) getSystemService(Context.LOCATION_SERVICE);
        boolean GPSstatus = myManager
                .isProviderEnabled(LocationManager.GPS_PROVIDER);

        if (GPSstatus) {
            _gps.getMyLoction();

            try {
                TimeUnit.SECONDS.sleep(3);
                intent.putExtra("latitude", _gps.getLatitude());
                intent.putExtra("longitude", _gps.getLongitude());
                intent.putExtra("GPSstatus", GPSstatus);
            } catch (InterruptedException e) {

            }

            sendBroadcast(intent);

        } else {

            try {

                TimeUnit.SECONDS.sleep(1);
                intent.putExtra("latitude", 0);
                intent.putExtra("longitude", 0);
                intent.putExtra("GPSstatus", GPSstatus);
                sendBroadcast(intent);

            } catch (InterruptedException e) {

            }

        }

    }

}

}

当我尝试调用＆＃34; _gps.getMyLoction（）＆＃34;

时，

应用程序崩溃

获得位置的方法;

public void getMyLoction() 
{
    _locationManager = (LocationManager) _context.getSystemService(LOCATION_SERVICE);
    _isGPSEnabled = _locationManager.isProviderEnabled(LocationManager.GPS_PROVIDER);

    if (_isGPSEnabled)
    {               
        this._canGetGPSLocation = true;

        if (_location == null)
        {               
            _locationManager.requestLocationUpdates(LocationManager.GPS_PROVIDER,0,0, this);                        
             if (_locationManager != null)
             {
                 _location = _locationManager.getLastKnownLocation(LocationManager.GPS_PROVIDER);
                 setLocation(_location);
            }
        }
    }       
}

也许这不是一个很好的实现从gps获得自动定位，我认为这个解决方案gps甚至在活动的后台工作中给出了位置。你可以帮助我，也许还有另外一个想法，如果这是蝙蝠的想法。

非常感谢
