Follow the steps

1. Create file named test.php and copy your php code in that file.
2. Copy that file in xamp server root folder ( in side WWW directory)
3. Make sure your mobile and computer connected to same WiFi router if so then copy the IP address of your system.
4. Copied IP address will your server IP . You may need to do search port number.
5. After above 4 steps you end up with URL some thing like this http://IP adreas : port number/test.php Example http://192.168.1.1:8080/test.php
6. Run your xamp server.
7. Set this url in your android http request.
8. Look for errors n Google .
