unhandled exception - Android - Error referencing another class -

i'm giving shot @ creating class can pass in of parameters stored procedure execution of return dataset.

here call

  @override     protected void doinbackground(void... params) {         log.i(tag, "doinbackground");         list<string> myargs = new arraylist<string>();         myargs.add("_caseid|apples");          webservicescontroller.soapactionexecutestoredprocedure("djprovider_delete", myargs);           return null;     } 

i'm getting error @ webservicescontroller.soapactionexecutestoredprocedure. error unhandled exceptions xmlpullparser,javaioexception.

this class i'm calling

    public static void soapactionexecutestoredprocedure(string method_name,list<string> argumentpipevalue) throws xmlpullparserexception, ioexception {     //make new soap object     soapobject request = new soapobject(namespace, method_name);      //add arguments in     (string arg : argumentpipevalue) {         string[] splitargs = arg.split("|");         request.addproperty(splitargs[0], splitargs[1]);     }      soapserializationenvelope soapenvelope = new soapserializationenvelope(soapenvelope.ver11);     soapenvelope.dotnet = true;     soapenvelope.setoutputsoapobject(request);      httptransportse transport = new httptransportse(namespace+asmxurl);        transport.call(namespace+method_name,soapenvelope);     resultstring = (soapprimitive) soapenvelope.getresponse();  } 

this first web service application android. i'm positive error because void has throws xmlpullparserexception, ioexception. not know how add syntax call.

also don't understand why if remove that, transport.call(namespace+method_name,soapenvelope); produces same error unhandled exception

any grealy appreciated!

put

@override     protected void doinbackground(void... params) {         log.i(tag, "doinbackground");         list<string> myargs = new arraylist<string>();         myargs.add("_caseid|apples");          try{              webservicescontroller.soapactionexecutestoredprocedure("djprovider_delete", myargs);             }catch(exception e){              }      return null; }
