here 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);          = conn.getinputstream();          long len = 0;          int ch = 0;          len = conn.getcontentlength();          if (len != -1) {              // read content-length bytes              system.out.println("if...");              (int = 0; < len; i++) {                  system.out.println("for loop...");                  if ((ch = is.read()) != -1) {                      system.out.println("appending");                      b.append((char) ch);                  }              }          } else {              // read till connection closed.              system.out.println("else...");              while ((ch = is.read()) != -1) {                  system.out.println("when...");                  len = is.available();                  system.out.println("append");                  b.append((char) ch);              }          }            string data = b.tostring();          alertdialog.builder builder = new alertdialog.builder(this);         builder.setmessage(data).setcancelable(false).setpositivebutton("ok", new dialoginterface.onclicklistener() {             public void onclick(dialoginterface dialog, int id) {                 xml_test.this.getparent();             }         });
