How to send data between android app and arduino via wifi

Hello guys, i am pretty new with arduino and android. i have developed all the modules of arduino like checking temperature, turn on and off lights and other appliances. I also developed the basic android app Like buttons through which arduino device is suppose to control. No i don't know how to connect these two devices in order to complete this project.

thanks in advance

P.S: I read it somewhere on the internet that, Server should be created on the arduino wifi module and then connect android app with that server

Put the Arduino away for now. Learn how to do what you want to do using two PCs, with one as server and the other as client. When you understand what a server does, and what a client does, then making the Arduino act as a server is simple. There are even examples provided with the IDE for the ethernet shield or the WiFi shield.
