emulator - internet connection issue

I have set my proxy settings in emulator and I can access normal internet on emulator's browser. But when I try to run my application, it gives error But when I change my URL to services running inside my organisation I can fetch data!!!

What is the issue here and how could I connect to URLs outside my org through my app???

Thanks Abhinav Tyagi

here is my code:

         StringBuffer b = new StringBuffer();
         System.out.println("try");
         String registrationUrl = "http://google.com";
         url = new URL(registrationUrl);  
         System.out.println("url");
         URLConnection connection = url.openConnection(); 
         System.out.println("open connection");
         conn = (HttpURLConnection) connection;         
         int responseCode = conn.getResponseCode();  
         System.out.println(responseCode);
         is = conn.getInputStream();
         long len = 0;
         int ch = 0;
         len = conn.getContentLength();
         if (len != -1) {
             // Read exactly Content-Length bytes
             System.out.println("IF...");
             for (int i = 0; i < len; i++) {
                 System.out.println("For Loop...");
                 if ((ch = is.read()) != -1) {

                     b.append((char) ch);
                 }

I dont have much time to go through what you actually need but if you wanna apply proxy to your application check the following examples..
