在模拟器或智能手机中，HttpClient与HttpURLConnection的连接速度非常慢

Question

我正在通过邮件提交我的服务器并发送我的服务器，阅读json。

有一个很大的延迟，我有一个错误

 //VERY SLOW HERE =( 1 a 5 min

httpURLConnection c = ( HttpURLConnection ) u.openConnection (); 
//or 
response = httpclient.execute(httpget); //get or post

和

可能是什么？怎么解决？

执行操作的代码段下方。

这些行在doInBackgrund方法asynktask中。模拟器是4.4.2 google apis或＆gt; 4.0（因为推送通知）。

选项1：

        URL u = new URL(url);
        HttpURLConnection c = (HttpURLConnection) u.openConnection();
       //VERY SLOW HERE =( 1 a 5 min open connection
        c.setRequestMethod("HEAD");
        // c.setRequestProperty("Connection", "Keep-Alive");
        c.setRequestProperty("Content-length", "0");
        c.setUseCaches(false);
        c.setAllowUserInteraction(false);
        c.setConnectTimeout(timeout);
        c.setReadTimeout(timeout);
        c.connect();
        int status = c.getResponseCode();

        switch (status) {
        case 200:
        case 201:
            BufferedReader br = new BufferedReader(new InputStreamReader(
                    c.getInputStream()));
            StringBuilder sb = new StringBuilder();
            String line;
            while ((line = br.readLine()) != null) {
                sb.append(line + "\n");
            }
            br.close();
            return sb.toString();
        }

选项2：

    HttpClient httpclient = new DefaultHttpClient();
    HttpParams httpParameters = httpclient.getParams();
    HttpConnectionParams.setConnectionTimeout(httpParameters, 5000);
    HttpConnectionParams.setSoTimeout(httpParameters, 5000);
    HttpConnectionParams.setTcpNoDelay(httpParameters, true);

    HttpPost httpget = new HttpPost(url);

    HttpResponse response = null;

    try {

        response =httpclient.execute(httpget); //VERY SLOW HERE =( 1 a 5 min

        HttpEntity entity = response.getEntity();

        if (entity != null) {
            InputStream instream = entity.getContent();
            String json = toString(instream);
            instream.close();

通常早期工作，模拟器中的时间不超过10秒。请帮帮我=（
