将数据从Android应用程序发送到PHP服务器

Here is my android code which executes normally I debugged it and says data sent.

public void postRegistrationData(final String result) {
        // Create a new HttpClient and Post Header
        Thread thread = new Thread(new Runnable(){
            @Override
            public void run() {
                try {
                    try {
                        URL url;
                        HttpURLConnection urlConn;

                        url = new URL ("http://192.168.*.**/server/mypage.php");
                        urlConn = (HttpURLConnection)url.openConnection();
                        urlConn.setDoInput (true);
                        urlConn.setDoOutput (true);
                        urlConn.setUseCaches (false);
                        urlConn.setRequestProperty("Content-Type","application/json");   
                        urlConn.setRequestProperty("Accept", "application/json");
                        urlConn.setRequestMethod("POST");
                        urlConn.connect();  
                        //Create JSONObject here
                        JSONObject jsonParam = new JSONObject();
                        jsonParam.put(result, true);

                        // Send POST output.
                        /*printout = new DataOutputStream(urlConn.getOutputStream ());
                        printout.writeUTF(URLEncoder.encode(jsonParam.toString(),"UTF-8"));
                        Log.i("NOTIFICATION", "Data Sent");
                        printout.flush ();
                        printout.close ();*/
                        OutputStreamWriter os = new OutputStreamWriter(urlConn.getOutputStream(), "UTF-8");
                        os.write(jsonParam.toString());
                        Log.i("NOTIFICATION", "Data Sent");
                        os.close();

                    } catch (MalformedURLException muex) {
                        // TODO Auto-generated catch block
                        muex.printStackTrace();
                    } catch (IOException ioex){
                        ioex.printStackTrace();
                    } catch (JSONException jex) {
                        // TODO Auto-generated catch block
                        jex.printStackTrace();
                    }
                } catch (Exception e) {
                    e.printStackTrace();
                    Log.e("ERROR", "There is error in this code");
                }
            }
        });

        thread.start(); 
    }

Here is the server(XAMPP) side PHP code which inserts data correctly when I run it but doesn't from the android app on my phone. I read all the similar responses in this site and others but their solutions didn't work for me for the last 2 days and decided to see if someone can help me. Your help is much needed and appreciated.

<?php
        header('Content-type: application/json');
            // connect to the database
            $servername = "localhost";
            $username = "root";
            $password = "password";
            $dbname = "db"; 
            $received = json_decode(stripslashes($_POST['json']));
            // if text data was posted
           if(isset($received['result'])){
            //print_r($_POST);
            try {
                $conn = new PDO("mysql:host=$servername;dbname=$dbname", $username, $password);
                // set the PDO error mode to exception
                $conn->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
                //$data   = urldecode($_POST['regid']);
                $sql = "INSERT INTO table (regID) VALUES ('$received')";
                // use exec() because no results are returned
                $conn->exec($sql);
                echo "New record created successfully";
            } catch (PDOException $e) {
                echo $sql . "<br>" . $e->getMessage();
            }
            $conn = null;
            }elseif ($received === NULL) {
                echo "Not value passed!!!!!!!!!!!!";
    }
        ?>

This is the logcat log.

    Look like you are missing the KeyName for the post data. try this 

    .....
String postData="json="+jsonParam.toString();
.....

 os.write(postData);
