Question

我的应用程序需要调用多个AsyncTask任务。我收到错误

Android AsyncTask #2 calls detach()
Android AsyncTask #3 calls detach()
...

这是什么意思？

另外，如何为API 14 ++同时运行多个AsyncTask

这就是我使用Async的方式

   private void callAPI() {
    new AsyncTask<Void, Void, String>() {

            protected String doInBackground(Void... parameters) {



                List<NameValuePair> params = new ArrayList<NameValuePair>();
                params.add(new BasicNameValuePair("user_id",    user_id));

                return api.post("", params);


            }//end doInBackground


            protected void onPostExecute(String result) {
                Log.i(TAG + "POST() => " + result);


            }//end onPostExecute
        }.execute(); //end AsyncTask
      }

logcat的
