Is it possible to have an app interact with a PC over one's own wifi?

Question

I'm new to Android development, and one of my app's function (at least on paper) would be interacting with a PC of choice and saving images. I came across Wifi Peer-to-Peer, and it appears that I might be able to do that but there is no official documentation on it.

I also came across this question which seems to imply that I may be able to do so, but I would like some verification.

Answer 1

Yes it is possible.

You can use TCP. So you can do what you like, you just need the internet permission. Ad hoc networks are also possible, but I would not use them better use a given infrastructure.
