应用程序在姜饼中正常运行但在kikat中死亡。这是logcat：

错误似乎与网络请求有关，但为什么会发生在kikat而不是gingenbread。

网络请求代码：

item_name_view = (EditText) findViewById(R.id.item_name);
        item_quantity_view = (EditText) findViewById(R.id.item_quantity);

        item_name = item_name_view.getText().toString();
        Log.w("item name", item_name);
        item_quantity = item_quantity_view.getText().toString();
        // Creating HTTP client
        HttpClient httpClient = new DefaultHttpClient();
        // Creating HTTP Post
        HttpPost httpPost = new HttpPost(SUBMISSION_URL);


        // Building post parameters
        // key and value pair
        List<NameValuePair> nameValuePair = new ArrayList<NameValuePair>(3);
        nameValuePair.add(new BasicNameValuePair("code", scanContent));
        nameValuePair.add(new BasicNameValuePair("name", item_name));
        nameValuePair.add(new BasicNameValuePair("quantity", item_quantity));

        // Url Encoding the POST parameters
        try {
            httpPost.setEntity(new UrlEncodedFormEntity(nameValuePair));
        } catch (UnsupportedEncodingException e) {
            // writing error to Log
            e.printStackTrace();
        }

        // Making HTTP Request
        try {
            HttpResponse response = httpClient.execute(httpPost);

            // writing response to log
            Log.d("Http Response:", response.toString());
            //response_text.setText(getResponseBody(response).replaceAll("<.*>", " "));
            response_text.setText(getResponseBody(response));
        } catch (ClientProtocolException e) {
            // writing exception to log
            e.printStackTrace();
        } catch (IOException e) {
            // writing exception to log
            e.printStackTrace();

        }
    }

应用程序通过邮件向服务器发出请求，并接收要在活动中显示的响应。这对姜饼坚果应用程序的工作正常，当请求进入网络时会崩溃。
