Welcome to the B4X community
@oleg_
Once you have studied the B4X getting started booklet that has been expertly written by
@klaus, I would recommend that you quickly looking at this cross platform example(s) (a simple Simon Says game) in the links below. This cross platform example is basically one set of code that is running the same game example on Android, iOS, Windows and MacOS operating systems. This is a relatively simple one code fits all example for beginners. As long as you use B4XPages with XUI, you should be able to accomplish most (if not all) of the cross platform projects you would probably like to create.
The two links below are for B4A (Android) and also B4J (Desktops), they download the exact same zip file and share the same simple to follow source code. You can open the project twice (one in B4A and the other in B4J) and for example when you change the source code in B4A, you will see the source code changes happen in B4J just a few seconds later.

Hello to you all, I decided to recreate this simple but effective game example, the game is based on the B4XPages library. The game is designed for hand, eye and memory coordination, so I called it 'Erel Says' ;) I've tried to make the code as simple as possible to follow for new to B4X...
