How to connect an Android smartphone to a PC (Windows) via Wi-Fi?

Question

Android

Good day to all!
I am hatching the idea of ​​​​an application for the implementation of which it is necessary that a smartphone or several can exchange data with a PC. Not via the Internet, but directly over the network (Wi-Fi) / The data that will be chasing between the smartphone and the PC are tables. So the main condition is that the PC does not have to install a large bunch of applications (all sorts of web servers and other things) for this connection to work.
Please tell me how to implement. If it is not difficult to explain the general scheme of operation of such a connection and what technologies should be used.
I will implement this in Java, but if you need to use something else for a part of the PC, please tell me about it))
Thank you very much in advance for the answers !!

Answer 1

Actually, both in Windows and in android devices with wifi there is an access point mode, and without third-party programs.
You create an access point, connect, after which a full-fledged IP - TCP network appears between the devices with IP 192.168.43.1-255 with all technologies:
With this IP 192.168.43.1, you can raise all types of
remote control servers (RDP), FTP video streaming and so on. .
done by pressing three

На этой, что надо зайти в свойства соединения на компе, и открыть порты FTP и RDP (но это не обязательно можно и без них):

Answer 2

Look towards BitTorrent Sync
A simple client is installed on a PC and a phone. Then you share the folder on your PC and add it to your phone through the link.
Now you just put the necessary files in this folder, and the phone itself will periodically synchronize with it.

You can open a server on any port of your smartphone, and the PC connects to it and exchanges data. (If I described correctly)
Look at how AirDrod is implemented, as for me, it's very convenient.
