php - 为什么 Http Post 仅适用于 API 10？

Question

这是我的代码

                List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>(1);
                nameValuePairs.add(new BasicNameValuePair("nama", nama));
                nameValuePairs.add(new BasicNameValuePair("pesan", s));

                try {
                    HttpClient httpClient = new DefaultHttpClient();
                    HttpPost httpPost = new HttpPost("http://192.168.173.1/chatgroup/insert.php");
                    httpPost.setEntity(new UrlEncodedFormEntity(nameValuePairs));
                    HttpResponse response = httpClient.execute(httpPost);
                    HttpEntity entity = response.getEntity();
                    is = entity.getContent();
                    textchat.setText("");
                    getData();

                } catch (ClientProtocolException e1) {
                    Log.e("ClientProtocol", "Log_tag");
                    e1.printStackTrace();
                } catch (UnsupportedEncodingException e1) {
                    e1.printStackTrace();
                } catch (IOException e1) {
                    Log.e("IOException", "Log_tag");
                    e1.printStackTrace();
                }

我在 API 10[Gingerbread] 中构建了这个并成功工作，...

但是，如果我为 API 11 构建> 不起作用并强制关闭应用程序..这里的任何人都可以给我建议，..或者此代码仅适用于 api 10？

注意:我在manifest.xml中使用uses-permision Internet:D谢谢您的回复

尝试这样

 try {
                URL url = new URL(url);
                HttpURLConnection conn = (HttpURLConnection)url.openConnection();
                conn.setRequestMethod("POST");
                conn.setRequestProperty("Content-Type", "application/json");
                conn.setDoOutput(true);

                JSONObject postDataParams = new JSONObject();
                try {
                    postDataParams.put("nama", nama);
                    postDataParams.put("pesan", s);
                } catch (JSONException e) {
                    e.printStackTrace();
                }

                PrintWriter out = new PrintWriter(conn.getOutputStream());
                out.print(postDataParams);
                out.close();

                int responseCode=conn.getResponseCode();

            } catch (UnsupportedEncodingException e) {
                e.printStackTrace();
            } catch (ClientProtocolException e) {
                e.printStackTrace();
            } catch (IOException e) {
                e.printStackTrace();
            }
