HttpPost在使用Thread的jellybean中不起作用

Question

我正在尝试创建与数据库的连接，并且它在gigerbread 2.3.6中没有问题，而且在高于jellybean os中没有。

这是我的代码 -

    new Thread(new Runnable() {
           public void run() {
               select();

           }                        
    }).start();

选择方法 - （我从edittext获取id）

public void select()
{
    ArrayList<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>();

String id="1";
nameValuePairs.add(new BasicNameValuePair("id",id));

    try
    {
    HttpClient httpclient = new DefaultHttpClient();
        HttpPost httppost = new HttpPost("http://yangoninnovation.com/mmuniteddbphp/conn.php");
        httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));
        HttpResponse response = httpclient.execute(httppost); 
        HttpEntity entity = response.getEntity();
        is = entity.getContent();
        txvstartstatus.setText("connected ...");
}
    catch(Exception e)
{

        txvstartstatus.setText("No Internet connection: ");
}     

    try
    {
        BufferedReader reader = new BufferedReader
            (new InputStreamReader(is,"iso-8859-1"),8);
            StringBuilder sb = new StringBuilder();
            while ((line = reader.readLine()) != null)
    {
            sb.append(line + "\n");
        }
            is.close();
            result = sb.toString();

            String re2;
            re2=result.substring(result.lastIndexOf(":"));
            re2=re2.substring(2, re2.lastIndexOf('"'));

            txvstartstatus.setText(re2);


}
    catch(Exception e)
    {
        txvstartstatus.setText("No Internet connection: ");
}     
}

我无法控制连接更高版本的Android版本。请帮助我。我的select（）在较低版本中成功运行。我该怎么解决呢提前致谢。这个问题让我陷入了大约一个月的困境。希望你可以帮忙！
