java - How can I transfer data between two phones in a local wireless network for testing?

Question

For testing purposes, I'm managing to develop a chat app to work through local wireless network. What would be the best options for the communication transfer? (assuming that the only information that each phone have it's the local IP) Sockets?

I referred chat because It's just for testing, my purpose is to transfer data like value of some variables, arrays etc.

Appreciate any idea/suggestion :)

Answer 1

Probably one of the simplest options would be to just use a Socket, wrap its streams in a PrintWriter and a LineNumberReader and then send JSON-encoded data. Should be more than adequate for small variables/arrays.
