android - 从android到GAE的未知主机异常

Question

我正在尝试从 android 发布到 GAE，我遇到了未知的主机异常。这是我的代码，

HttpClient httpclient = new DefaultHttpClient();  
    HttpPost httppost = new HttpPost("http://silver-kites.appspot.com");  

    try {  
        // Add your data 
        List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>(2);  
        nameValuePairs.add(new BasicNameValuePair("abc", "123"));  
        nameValuePairs.add(new BasicNameValuePair("xyz", "456"));  
        httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));  

        // Execute HTTP Post Request  
        HttpResponse response = httpclient.execute(httppost);
        HttpEntity entity = response.getEntity();
        if(entity != null){
          InputStream inputStream = entity.getContent();
          ResponseText.setText(convertStreamToString(inputStream));
        }
    } catch (ClientProtocolException e) {
        ResponseText.setText(e.getMessage()); 
    } catch (IOException e) {
        ResponseText.setText(e.getMessage());
    }

当我尝试连接到 localhost:8888 时，连接被拒绝。我不知道如何通过这个。帮助我。

我也试过了，在 android 中仍然出现未知主机异常。是否需要做任何设置才能访问 HTTP？或者在模拟器中 http 将无法工作？

我设置了 <uses-permission android:name="android.permission.INTERNET"></uses-permission>在 android list xml 中。仍然没有希望。

有帮助吗？我 checkin 了 GAE，但我的请求没有到达那里。

这是我的代码，

HttpClient httpclient = new DefaultHttpClient();  
    HttpPost httppost = new HttpPost("http://silver-kites.appspot.com/silverscores");  

    try {  

        nameValuePairs.add(new BasicNameValuePair("name", "JP"));
        nameValuePairs.add(new BasicNameValuePair("seconds", "123"));

        httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));  

        // Execute HTTP Post Request  
        HttpResponse response = httpclient.execute(httppost);
        HttpEntity entity = response.getEntity();
        if(entity != null){
          InputStream inputStream = entity.getContent();
          ResponseText.setText(convertStreamToString(inputStream));
        }
    } catch (ClientProtocolException e) {
        ResponseText.setText(e.getMessage()); 
    } catch (IOException e) {
        ResponseText.setText(e.getMessage());
    }
