我在三星 S3 中没有得到经纬度。在其他设备上，我的代码工作正常，并且得到了正确的经度和经度。下面是我获取经度和经度的代码。

public class MainActivity extends Activity {
TextView textView1;
Location currentLocation;
double currentLatitude,currentLongitude;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    textView1 = (TextView) findViewById(R.id.textView1);

    findLocation();


}

 public void findLocation() {

        LocationManager locationManager = (LocationManager) this
                .getSystemService(Context.LOCATION_SERVICE);

        LocationListener locationListener = new LocationListener() {

            public void onLocationChanged(Location location) {

                updateLocation(location,currentLatitude,currentLongitude);

                Toast.makeText(
                        MainActivity.this,
                        String.valueOf(currentLatitude) + "\n"
                                + String.valueOf(currentLongitude), 5000)
                        .show();

                }

            public void onStatusChanged(String provider, int status,
                    Bundle extras) {
            }

            public void onProviderEnabled(String provider) {
            }

            public void onProviderDisabled(String provider) {
            }
        };

        locationManager.requestLocationUpdates(
                LocationManager.NETWORK_PROVIDER, 0, 0, locationListener);

    }


    void updateLocation(Location location,double currentLatitude,double currentLongitude) {
            currentLocation = location;
            this.currentLatitude = currentLocation.getLatitude();
            this.currentLongitude = currentLocation.getLongitude();


            textView1.setText(String.valueOf(this.currentLatitude) + "\n"
                    + String.valueOf(this.currentLongitude));

        }
}

在上面的代码中，onLocationChanged() 方法没有在 S3 中执行，并且相同的代码在三星 S3 设备中不起作用。在其他设备中它工作正常。我在其他设备中得到正确的纬度和经度。请帮我整理一下这个问题..
