java - DEBUG/SntpClient(70) : request time failed: java.net.SocketException:Android 上的协议(protocol)不支持地址族

Question

我创建这样的代码:

try {
    int ct_id;
    String ct_name;
    try{
        HttpClient httpclient = new DefaultHttpClient();
        HttpPost httppost = new HttpPost("http://10.0.2.2/update.php");
        httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));
        HttpResponse response = httpclient.execute(httppost);
        HttpEntity entity = response.getEntity();
        is = entity.getContent();
    }catch(Exception e){
        Log.e("log_tag", "Error in http connection"+e.toString());
    }
    //convert response to string
    try{
        BufferedReader reader = new BufferedReader(new InputStreamReader(is,"iso-8859-1"),8);
        sb = new StringBuilder();
        sb.append(reader.readLine() + "\n");
        String line="0";
        while ((line = reader.readLine()) != null) {
            sb.append(line + "\n");
        }
        is.close();
        result=sb.toString();
    }catch(Exception e){
        Log.e("log_tag", "Error converting result "+e.toString());
    }
    //paring data
    int max = 0;
    try{
        jArray = new JSONArray(result);
        JSONObject json_data=null;
        for(int i=0;i<jArray.length();i++){
            json_data = jArray.getJSONObject(i);
            ct_id=json_data.getInt("max(id)");
            ct_name=json_data.getString("date");
            max = ct_id;
        }
    }
    catch(JSONException e1){

} catch (ParseException e1) {
    e1.printStackTrace();
}

但是当我调试的时候出现了:

07-03 08:50:42.657: DEBUG/SntpClient(70): request time failed: java.net.SocketException: Address family not supported by protocol

这是什么意思？以及如何解决？

这看起来像一个本地 url，你确定你的 apache 在 80 端口上运行吗？您可以尝试访问此网址吗 http://10.0.2.2/update.php在桌面浏览器中，你看得正确吗？通常仅当套接字无法与服务器建立连接时才会出现此错误。
