解决方案
一个简单的方法将数据发送到服务器是使用谷歌凌空库。 http://developer.android.com/intl/zh-cn /training/volley/index.html
i used list view in my android app i wants send the users current position to the server. for this i used the following code........
public class Home extends ListActivity {
private ProgressDialog pDialog;
// URL to get contacts JSON
private static String url = "http://api-11hr.anovatesoft.com/v1/list";
// JSON Node names
private static final String TAG_CONTACTS = "contacts";

ListView lv = getListView();
// Listview on item click listener
lv.setOnItemClickListener(new OnItemClickListener() {
@Override
