how make communication between an Android app and a windows app?

Question

how can i transfer string or anything from my android app to my windows app?

Answer 1

You can just use PHP and direct information/datas from android to PC and vice versa. Or you can just make the code create a new file that stores the data and simply cable the file.
(Like how some fully offline games work, there is a hidden folder that contains data of your saved progress in the game. If you send those files to other players, they can use your saved progress and play it fine. I think you should get what I mean.)
