Regarding Webservice problem

Question

HI All,

I m developing one android application and calling SOAP web service which is .net based web service.

The Problem is that when web serivce is working fine my application is working without any issue. but when the server is down my app does not work. i think i haven't done the exception handling properly.

if(Result.equals("Loginsuccessfull")) { Intent i = new Intent(); i.setClassName("com.android.example","com.android.istock.newScreen"); startActivity(i); } else { alert(); }

       }
       catch(Exception e)
       {
           e.printStackTrace();
       }

Can anybody help me..
