Java android应用程序URL连接获取请求无法工作

我有个问题

我不明白为什么下面的代码不能工作

这是一个简单的应用程序，它向一些php片段发送GET请求，这些php片段应该在表中插入一行

我不明白为什么它不起作用

请帮忙

您需要使网络操作脱离主线程

我刚刚使用AsyncTask实现并测试了此功能：

class MyAsyncTask extends AsyncTask<Void, Void, String> {

    @Override
    protected String doInBackground(Void... params) {
        StringBuilder result = new StringBuilder();
        URL url;
        HttpURLConnection urlConnection = null;
        try {
            url = new URL("http://www.chatty.co.il/biyum.php?q=mkyong");
            urlConnection = (HttpURLConnection) url.openConnection();
            InputStream in = urlConnection.getInputStream();
            InputStreamReader isw = new InputStreamReader(in);
            int data = isw.read();
            while (data != -1) {
                char current = (char) data;
                data = isw.read();
                result.append(current);
            }
        } catch (Exception e) {
            e.printStackTrace();
        } finally {
            if (urlConnection != null) {
                urlConnection.disconnect();
            }
        }

        return result.toString();
    }

    @Override
    protected void onPostExecute(String result) {
        Toast.makeText(getApplicationContext(),"GET:"+result,Toast.LENGTH_LONG).show();
    }
}

致祝酒辞：


   <?php
require('connect.inc.php');
$update_offline="INSERT INTO offline_waiters (user_partner,mail,chat_room) VALUES(0,'gavno','gavno')";
$query_run= mysqli_query($conn,$update_offline);

echo "new";

    startBtn.setOnClickListener(new View.OnClickListener(){

            new MyAsyncTask().execute();
