When you click on a button, does it call the API?

Question

Java

Hello.
How to make it so that when you click on a button in an Android application, a method is called from some server?
For example, so that I click on a button, and then my phone accesses the API of my site (site.ru/api?code=123).

Answer 1

Well, in the button handler, write a call to the server, for example.
What do you know about event handlers and buttons in general?
