Como faço para conectar o banco de dados mysql e inserir dados nele usando o código android

HttpPost httppost = new HttpPost("http://10.0.2.2/insert.php");

        // this variables is used for connecting to database and server
        $host="yourhost";
        $uname="username";
        $pwd='pass';
        $db="dbname";

        // this is for connecting
        $con = mysql_connect($host,$uname,$pwd) or die("connection failed");
        mysql_select_db($db,$con) or die("db selection failed");

        // getting id and name from the client
         if(isset($_REQUEST)){
        $id=$_REQUEST['id'];
        $name=$_REQUEST['name'];}


       // variable used to tell the client whether data is stored in database or not

        $flag['code']=0;

        // for insertion
        if($r=mysql_query("insert into emp_info values('$name','$id') ",$con))
        {
            //if insertion succeed set code to 1
            $flag['code']=1;
            echo"hi";
        }
        // send result to client that will be 1 or 0
        print(json_encode($flag));

        //close
        mysql_close($con);
    ?>

 JSONObject json_data = new JSONObject(result);
            code=(json_data.getInt("code"));

            if(code==1)
           {
        Toast.makeText(getBaseContext(), "Inserted Successfully",
            Toast.LENGTH_SHORT).show();
            }
            else
          {
        Toast.makeText(getBaseContext(), "Sorry, Try Again",
            Toast.LENGTH_LONG).show();
            }
