title: How to create an Android app to control Arduino over Wi-Fi?
body: <p>I have an Arduino Mega board. I've connected the <a href="http://www.sparkfun.com/products/9367" rel="noreferrer">WiFly</a> module to it and established connection with my Android phone. Now I want to make a simple app for my Android, where I press a button and the <a href="http://en.wikipedia.org/wiki/Light-emitting_diode" rel="noreferrer">LED</a> on the Arduino board turns on. </p>
  
  <p>In fact, I've already made an app (in Eclipse) with a button, and if I press it, I get a toast message saying the button is pressed. Now, how do I implement the <a href="http://en.wikipedia.org/wiki/Wi-Fi" rel="noreferrer">Wi-Fi</a> functionality to it and enable it to light up the Arduino's LED?</p>
