pleas check your manifest file.whether have you added those permissions or not.

See the updated answer:

protected void showCurrentLocation() 
       {
         geocoder = new Geocoder(this); 
         locationManager = (LocationManager) getSystemService(Context.LOCATION_SERVICE);
         locationManager.requestLocationUpdates(
                    LocationManager.NETWORK_PROVIDER, 
                    MINIMUM_TIME_BETWEEN_UPDATES, 
                    MINIMUM_DISTANCE_CHANGE_FOR_UPDATES,
                    myLocationListener
            );
         timer = new Timer();
         timer.schedule(new GetLastLocation(),20000);

       }

     class GetLastLocation extends TimerTask {

            @Override
            public void run() {
                timer.cancel();
                locationManager.removeUpdates(locationListener);
                 Location location = locationManager.getLastKnownLocation(LocationManager.NETWORK_PROVIDER);
                   System.out.println("loc.."+location);
                   if (location != null) 
                   {
                   String message = String.format("Location \n Longitude: %1$s \n Latitude: %2$s",
                                location.getLongitude(), location.getLatitude());
                       Toast.makeText(ShowActivity.this, message,
                               Toast.LENGTH_LONG).show();
                  //acTextView.setText(message);
                   try {
                          List
 addresses = geocoder.getFromLocation(location.getLatitude(), location.getLongitude(), 10); //<10>
                          for (Address address : addresses) {
                              System.out.println("my location .."+address.getAddressLine(0));
                            acTextView.setText(address.getAddressLine(0));
                          }



                        } catch (IOException e) {
                          Log.e("LocateMe", "Could not get Geocoder data", e);
                        }
                    }
                    else
                    {
                    AlertDialog.Builder alertbox1 = new AlertDialog.Builder(this);
                    alertbox1.setMessage("No GPS or network ..Signal please fill the location manually!");
                    alertbox1.setNeutralButton("Ok", new DialogInterface.OnClickListener() {
                    public void onClick(DialogInterface arg0, int arg1) 
                    {}});
                    alertbox1.show();
                    }
                }   
                return;
            }
        }

     /** The location listener. */
        LocationListener myLocationListener = new LocationListener() {

            public void onLocationChanged(Location location) {

            }
