Android 2.3.3 GPS冻结

Question

我正在测试不同API的AVD。在4.0.3上工作正常，但是当我用2.3.3测试它时，应用程序崩溃并且AVD每次都重新启动。

这是我的服务类：

public class SendIntentService extends Service{
    @Override
    public int onStartCommand(Intent intent, int flags, int startId){
       MyLocationListener myLocationListener = new MyLocationListener(this);
       Location location = myLocationListener.getLocation();

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

       Log.e("TEST", "lat: " + latitude + " | long: " + longtitude);    

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

这就是我获取用户位置的方式：

public class MyLocationListener implements LocationListener {

    private Context context;
    private Location location;
    private LocationManager locationManager;
    private double longtitude = 0.0;
    private double latitude = 0.0;

    public MyLocationListener(Context context){
        this.context = context;
    }

    public Location getLocation(){

        locationManager = (LocationManager) context.getSystemService(Context.LOCATION_SERVICE);
        boolean isGpsEnabled = locationManager.isProviderEnabled(LocationManager.GPS_PROVIDER);
        boolean isNetworkEnabled = locationManager.isProviderEnabled(LocationManager.NETWORK_PROVIDER);

        if (!isGpsEnabled && !isNetworkEnabled) return null;

        if (isNetworkEnabled){
            locationManager.requestLocationUpdates( LocationManager.NETWORK_PROVIDER, 
                                                    Constants.MIN_INTERVAL,
                                                    Constants.LOC_DISTANCE,
                                                    this);

            if (locationManager != null){
                location = locationManager.getLastKnownLocation(LocationManager.NETWORK_PROVIDER);
                if (location != null){
                    latitude = location.getLatitude();
                    longtitude = location.getLongitude();
                }
            }
        }

        if (isGpsEnabled){
            if (location == null){
                locationManager.requestLocationUpdates( LocationManager.GPS_PROVIDER,
                                                        Constants.MIN_INTERVAL,
                                                        Constants.LOC_DISTANCE,
                                                        this);

                if (locationManager != null){
                    location = locationManager.getLastKnownLocation(LocationManager.GPS_PROVIDER);

                    if (location != null){
                        latitude = location.getLatitude();
                        longtitude = location.getLongitude();
                    }
                }
            }
        }

        return location;
    }

    public double getLatitude(){
        return latitude;
    }

    public double getLongitute(){
        return longtitude;
    }

    @Override
    public void onLocationChanged(Location location) {
        // TODO Auto-generated method stub

    }

    @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

    }

}

权限在AndroidManifest中设置。正如我所说，在4.0.3上工作得很好，但在2.3.3上应用程序崩溃了。我不知道为什么。
