title: WiFi connection via android
body: <p>I need a tutorial on how to process data on android via wifi. F.e., I need to send some message to PC and receive some other message. How should I establish the connection? What should I do to be able to transfer data and how?</p>
  
  <p>Sorry for the dummy question, but I can't find good manual. I'll be grateful for as detailed manual as possible, or for ome simple example on etablishing wifi connection and sending/receiving simple mesages.</p>
