public class menu8_Fragment extends Fragment {
    View rootview;
    @Nullable
    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
        rootview = inflater.inflate(R.layout.menu8_layout, container, false);
        final EditText txt_monteur = (EditText)rootview.findViewById(R.id.txt_id_monteur_nr);
        final EditText txt_von = (EditText)rootview.findViewById(R.id.txt_von);

                System.out.println("working4");
                @SuppressWarnings("unused")
                String resultServer  = getHttpPost(url,params);
                Toast.makeText(getActivity(), "1 Record inserted...", Toast.LENGTH_LONG).show();
                System.out.println("working5");
      }
});
        return rootview;
    }
    public String getHttpPost(String url,List params) {
        StringBuilder str = new StringBuilder();
        HttpClient client = new DefaultHttpClient();
        HttpPost httpPost = new HttpPost(url);
        try {
            httpPost.setEntity(new UrlEncodedFormEntity(params, "UTF-8"));
            HttpResponse response = client.execute(httpPost);
            StatusLine statusLine = response.getStatusLine();
            int statusCode = statusLine.getStatusCode();
            if (statusCode == 200) { // Status OK
                HttpEntity entity = response.getEntity();
                InputStream content = entity.getContent();
                BufferedReader reader = new BufferedReader(new InputStreamReader(content));
                String line;
                while ((line = reader.readLine()) != null) {
                    str.append(line);
                }
            } else {
                Log.e("Log", "Failed to download result..");
            }
        } catch (ClientProtocolException e) {
            e.printStackTrace();
        } catch (IOException e) {
            e.printStackTrace();
        }
        return str.toString();
    }
 }
Leider erscheint folgender Fehler nach Drücken des Buttons:
