android - 如何在专用网络上检测 android GPS 位置

Question

您好，我有一个连接在私人 APN 上的 Android 手机上的应用程序，如果我无法导航到不在我的 APN 上的任何地方，我想知道如何获取 GPS 位置。

这是在我的应用程序上使用 GPS 的代码：

public double[] _getLocation (Context _context)
{
    // Get the location manager
    LocationManager locationManager = (LocationManager)_context.getSystemService (LOCATION_SERVICE);
    Criteria criteria = new Criteria ();
    String bestProvider = locationManager.getBestProvider (criteria, true);
    Location location = locationManager.getLastKnownLocation (bestProvider);

    LocationListener loc_listener = new LocationListener() {

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

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

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

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

    locationManager.requestLocationUpdates(bestProvider,0 ,0, loc_listener);
    location = locationManager.getLastKnownLocation (bestProvider);   

    double lat=0.00;
    double lon=0.00;

    try
    {
        lat = location.getLatitude ();
        lon = location.getLongitude ();
    }
    catch (NullPointerException e)
    {
        Toast.makeText(_context,"El GPS debe estar encendido, asegurate en configuracion-->Localizacion",Toast.LENGTH_LONG).show();
    }

    double[] result = {lat,lon};
    return result;
}
