Android application sends a request to the server, php script or something else gives the answer.
script.php:

<?php

Answer 4

If it is not critical that the data is on your computer, then it is better to use Parse.com for these purposes. This is a great backend option for mobile applications, and in general, when you don’t want to bother with the backend. There are other similar services.
