Question

I’m getting ArrayList of complex objects using KSOAP2 library based on this tutorial:

And I’m able to receive arrayList of objects. The problem is when the envelope have just one object… When I do:

//...Call webservice
Vector<SoapObject> vectorOfSoapObject = (Vector<SoapObject>)envelope.getResponse();
//pass Vector to ArrayList

It returns me an ClassCastException on this line, when I have just one object on the envelope. When I have more it works fine (I made debug to see this happening)…

What could be the problem?

I was able to solve this problem. Using the suggestion of @Pranalee, I made this:

//call webservice
Object o1 = envelope.getResponse();
if(o1 == null){//no devices updated
    Log.d("GetUpdatesThread","o1==null");
} else if(o1.getClass().toString().equals(new SoapObject("", "").getClass().toString())){//one device updated
    Log.d("GetUpdatesThread","class -- soapObject");
    SoapObject result = (SoapObject) envelope.getResponse();
    Device d = convertToDevice(result);
    devicesUpdated.add(d);
} else if (o1.getClass().toString().equals(new Vector().getClass().toString())){//more than one device updated
    Log.d("GetUpdatesThread","class -- vector");
    Vector<SoapObject> vectorOfSoapObject2 = (Vector<SoapObject>)envelope.getResponse();
    for (SoapObject soapObject : vectorOfSoapObject2) {
         Device d = convertToDevice(soapObject);
         devicesUpdated.add(d);
    }  
}
