Android : WebService and insert ListArrary with cast

I have a problem when inserting a string returned by a webService a ListArray integer.

I have a problem debugging is that the loop lacks an iteration and then not run some sentences. I put the code of the part that fails:

if (inputStream! = null)
{
   result = convertInputStreamToString (inputStream);
   Log.i ("Asyn", "result Volser:" + result);

   String [] aux = result.split (";");
   serviciosSi.clear ();

   for (int i = 0; i <aux.length; i ++)
   {
        Log.i ("Asyn", "for" + aux [i]);
        serviciosSi.add (Integer.parseInt (aux [i]));
        Log.i ("Asyn", "tamsi:" + serviciosSi.size ());
        Log.i ("Asyn", "insert aux" + serviciosSi.get (i));
   }
   Log.i ("Asyn", "tamsi:" + serviciosSi.size ());
   secure = "1";
   progressDialog.setProgress (43);
}

This is the logcat:

I/Asyn(8761): result volSer: 1;4;7  
I/Asyn(8761): for: 1
I/Asyn(8761): tamSI: 1
I/Asyn(8761): inserto aux: 1
I/Asyn(8761): for: 4
I/Asyn(8761): tamSI: 2
I/Asyn(8761): inserto aux: 4
I/Asyn(8761): for: 7

It should also show:

I/Asyn(8761): tamSI: 3
I/Asyn(8761): inserto aux: 7
I/Asyn(8761): tamSI: 3

and output for:

I/Asyn(8761): tamSI: 3

Can anyone help me?

Thank's you for your time and help.
