Hello guys,

I'm trying to connect my Android application with Tomcat web server running in the same computer.

This Activity is simple, only shows the HTML code from the index page of a server. It works with whatever URL on Internet, but I'm having problems getting the index page of my own Tomcat server (from my browser with "http://localhost:8080", there isn't any problem)

Using java Syntax Highlighting
  1. public class Localizador extends Activity {
  2.  
  3.     /** Called when the activity is first created. */
  4.  
  5.     @Override
  6.  
  7.     public void onCreate(Bundle savedInstanceState) {
  8.  
  9.                
  10.  
  11.         super.onCreate(savedInstanceState);
  12.  
  13.        
  14.  
  15.         EditText edit = new EditText(this);
  16.  
  17.  
  18.  
  19.         String server = "10.0.2.2";            
  20.  
  21.         int port = 8080;                  
  22.

  25.         try {
  26.  
  27.                
  28.  
  29.           Socket socket = new Socket( server, port);

I have read here (http://code.google.com/android/kb/commo ... lhostalias) I need use the IP 10.0.2.2 referer to localhost, but it doesn't work !

I have no clue about the problem and I'm sure it's a nonsense. :cry:

Please, could somebody help me to connect my Android application with my Tomcat server, running on the same host?

Thanks a lot in advance
