How to integrate phone with computer?

Question

Java

Good afternoon, I ran into a problem. There is a task: you need to make sure that certain actions occur on the computer when certain actions are taken on the phone. Those. if I press the number 10 on the phone, I get a green square on the computer, or if I enter some data on the phone, so that they are displayed on the computer. In view of the ignorance of Android development, I would like to ask a question how it is possible to connect a computer and a phone.

Answer 1

The easiest way is through Firebase . Write an android app using firebase and a desktop app using the same base. Any changes made by one application will be immediately received by another.
But you can also write your own data exchange server if you want difficulties.
