java - Android 与服务器的连接无法识别或引发错误。我究竟做错了什么？

Question

我正在尝试通过 Android 应用程序将 JSON 数据推送到服务器，但无法隔离问题。服务器根本没有收到连接，但客户端没有表明任何问题。

public void getServerData() throws JSONException, ClientProtocolException, IOException {
    DefaultHttpClient httpClient = new DefaultHttpClient();
    ResponseHandler <String> resonseHandler = new BasicResponseHandler();
    HttpPost postMethod = new HttpPost("HTTP://URL_GOES_HERE/FOLDER");
    List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>(2);
    //Log.v("JSON being sent", json.toString());
    nameValuePairs.add(new BasicNameValuePair("jsonString", json.toString()));
    postMethod.setEntity(new UrlEncodedFormEntity(nameValuePairs));
    String response = httpClient.execute(postMethod,resonseHandler);

    JSONObject jsonResponse = new JSONObject(response);
    Log.v("beginresponse","beginresponse");
    Log.v("server response", jsonResponse.toString());
    Log.v("endresponse","endresponse");
    //Log.v("msg to server", json.toString());

}

这是一些示例日志输出:

Answer 1

是的，我猜从 API 11 开始，服务器连接将无法在 UI 线程上工作。所以尝试将其放入异步任务中。
