Проблема в том, что я не могу отправлять данные методом POST

Ни один из кодов не помог мне передать данные через метод post, все отмеченные ошибки при запуске

Код:

 public class Registro extends Activity{

protected String pagina = "http://192.168.0.5/vcard/index.php";
protected WebView web;
protected String qr = "70", firstname = "Name", lastname = "Last",
            email = "email@hotmail.es", institucion = "ITA", movil = "9136161";


protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    web = (WebView) findViewById(R.id.webView1);

    postData();

    web.loadUrl(pagina);
}

public void postData() {
    // Create a new HttpClient and Post Header
    HttpClient httpclient = new DefaultHttpClient();
    HttpPost httppost = new HttpPost(pagina);

    try {
        // Add your data
        List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>(6);
                nameValuePairs.add(new BasicNameValuePair("qr", qr));
                nameValuePairs.add(new BasicNameValuePair("firstname", firstname));
                nameValuePairs.add(new BasicNameValuePair("lastname", lastname));
                nameValuePairs.add(new BasicNameValuePair("email", email));
                nameValuePairs.add(new BasicNameValuePair("institucion", institucion));
                nameValuePairs.add(new BasicNameValuePair("movil", movil ));
        httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));

        // Execute HTTP Post Request
        HttpResponse response = httpclient.execute(httppost);

    } catch (ClientProtocolException e) {
        // TODO Auto-generated catch block
    } catch (IOException e) {
        // TODO Auto-generated catch block
    }
} }

В конце концов, данные получены и загружается визитная карточка, но всегда загружается визитная карточка без данных

Используйте класс AsyncTask для postData()
