KSoap2 outOfMemoryError while doing a call Android

Question

I try to get some Data from a WebService using KSoap2.

The WebService responses a very large XML-File so while I'm doing the HttpTransportSE.call() I get an ouOfMemory Exception.

Is it possible to get a snipped response from a Soap Webservice? Or is there a way to write it directly in a file on the device? This is my Class to get the Data:

    public static SoapObject GetItemData()
{

    SoapObject request = new SoapObject(NAMESPACE, METHOD_NAME_ITEM_DATA);
    request.addProperty("Company", company);
    request.addProperty("SerialNumber", serialId);

    itemEnvelope = new SoapSerializationEnvelope(SoapEnvelope.VER11);
    itemEnvelope.dotNet = true;

    itemEnvelope.setOutputSoapObject(request);

    AndroidHttpTransportSE androidHttpTransport = new AndroidHttpTransportSE(URL);
    androidHttpTransport.debug = true;
    Log.d("==ITEM_URL==", URL);
    try
    {
       androidHttpTransport.call(SOAP_ACTION_ITEM_DATA, itemEnvelope);
       Log.d("==ItemVerbindung==", "Verbindung aufgebaut");
    }
    catch (Exception e)
    {
       e.printStackTrace();
       Log.d("==ItemVerbindung==", "HTTPCALL nicht ausgeführt");
    }

    try
    {
        itemResult = (SoapObject)itemEnvelope.getResponse();
        Log.d("==ItemResponse==", "PropertyCount: "+itemResult.getPropertyCount());
    }
    catch(ClassCastException e)
    {
        itemResult = (SoapObject)itemEnvelope.bodyIn;           
    } 
    catch (SoapFault e)
    {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }

    if(itemResult != null)
    {
        return itemResult;
    }   
    return null;
}

I have also coppied the HttpTransportSE.java and manipulated it to write directly in a file. But there I get an unvalid Token error.

I remember to have seen this problem before:

Two Recommendations:

1) Save your SOAP XML stream directly to disk as you download it. Don't store it in memory.

2) Parse it using a SAX-style parser, where you don't load the whole DOM in memory, but rather parse it in chunks.

I've read it already. I know that i have to stream it on disk but i don't know how. – Karas Nov 14 '12 at 11:18
I've already read it. I tried it this way but then i get an Unecpected Token Exception. – Karas Nov 14 '12 at 12:49

I found a solution without using the KSoap2 Library.

Here is the code:

try {

    java.net.URL url = new java.net.URL(URL);
    HttpURLConnection rc = (HttpURLConnection) url.openConnection();
    rc.setRequestMethod("POST");

    rc.setDoOutput(true);
    rc.setDoInput(true);

    rc.setRequestProperty("Content-Type", "text/xml; charset=utf-8");
    rc.addRequestProperty("User-Agent", HTTP.USER_AGENT);
    rc.setRequestProperty("SOAPAction", SOAP_ACTION_ITEM_DATA);
    OutputStream out = rc.getOutputStream();
    Writer wout;
    wout = new OutputStreamWriter(out);
    wout.write("<?xml version=\"1.0\" encoding=\"utf-8\"?>");
    wout.write("<soap:Envelope xmlns:xsi=\"http://www.w3.org/2001/XMLSchema-instance\" xmlns:xsd=\"http://www.w3.org/2001/XMLSchema\" xmlns:soap=\"http://schemas.xmlsoap.org/soap/envelope/\">");
    wout.write("<soap:Body>");
    wout.write("<GetItemData2 xmlns=\"http://localhost/HSWebBL\">");
    wout.write("<Company>" + company + "</Company>");
    wout.write("<SerialNumber>" + serialId + "</SerialNumber>");
    wout.write("</GetItemData2>");
    wout.write("</soap:Body>");
    wout.write("</soap:Envelope>");
    wout.flush();
    wout.close();
    rc.connect();

    Log.d("==CLIENT==", "responsecode: " + rc.getResponseCode() + " " + rc.getResponseMessage());
    InputStream in = new BufferedInputStream(rc.getInputStream(), BUFFER_SIZE);
} catch (ProtocolException e) {
    e.printStackTrace();
} catch (MalformedURLException e) {
    e.printStackTrace();
} catch (IOException e) {
    e.printStackTrace();
}

I use a SAXParser to parse the InputStream. In that way I don't get an outOfMemoryException and no parsing error anymore.

can you please post your code of how did you parse the above file.I am new to parsing this type of response in android. — Raj, Jul 03 '13 at 06:38
