I solve it. I added this code. it's working.
my Code
@Override
protected void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
init();
}
private void init()
{
//your webservice envelope
String envelope="<?xml version=\"1.0\" encoding=\"utf-8\"?><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/\"><soap:Body><GetContentTreeBySections xmlns=\"http://tempuri.org/\"><SectionsInclude>%s</SectionsInclude><DocumentCount>%s</DocumentCount><SortBy>%s</SortBy><SortOrder>%s</SortOrder><UserName>%s</UserName><Pass>%s</Pass></GetContentTreeBySections></soap:Body></soap:Envelope>";
String myEnvelope = String.format(envelope, "myParam1 value", "myParam2 value","myParam3 value","myParam4 value");
String url = "http://www.mywebserice.com/XMLGenerator/GenerateXML.asmx";
String soapAction = "http://tempuri.org/GetContentTreeBySections";
String response = CallWebService(url, soapAction, myEnvelope);
//Log.v("response", response);
Toast.makeText(getApplicationContext(), "this"+response,Toast.LENGTH_LONG).show();
String xml=response;
}
@Override
public boolean onCreateOptionsMenu(Menu menu)
{
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.activity_main, menu);
return true;
}
String CallWebService(String url,String soapAction,String envelope)
{
final DefaultHttpClient httpClient=new DefaultHttpClient();
// request parameters
HttpParams params = httpClient.getParams();
HttpConnectionParams.setConnectionTimeout(params, 10000);
HttpConnectionParams.setSoTimeout(params, 15000);
// set parameter
HttpProtocolParams.setUseExpectContinue(httpClient.getParams(), true);
// POST the envelope
HttpPost httppost = new HttpPost(url);
// add headers
httppost.setHeader("soapaction", soapAction);
httppost.setHeader("Content-Type", "text/xml; charset=utf-8");
String responseString="";
try
{
// the entity holds the request
HttpEntity entity = new StringEntity(envelope);
httppost.setEntity(entity);
// Response handler
ResponseHandler<String> rh=new ResponseHandler<String>() {
// invoked when client receives response
public String handleResponse(HttpResponse response)
throws ClientProtocolException, IOException {
// get response entity
HttpEntity entity = response.getEntity();
// read the response as byte array
StringBuffer out = new StringBuffer();
byte[] b = EntityUtils.toByteArray(entity);
// write the response byte array to a string buffer
out.append(new String(b, 0, b.length));
return out.toString();
}
};
responseString=httpClient.execute(httppost, rh);
}
catch (Exception e) {
Log.v("exception", e.toString());
}
// close the connection
httpClient.getConnectionManager().shutdown();
return responseString;
}

Rather than using ksoap, try using ice-soap library, which is open source. It's far better than ksoap and provides efficient library to send request and parse response using annotatations....

First of all never use Network Operations in main thread try always to insert network operations inside non-main thread like AsyncTask or any other worker thread. Second use the following code to get the result:
String message="";
SoapObject result = (SoapObject)envelope.bodyIn;
if(result != null)
{
message=result.getProperty(0).toString();
}
and also change the following code
Request.addProperty("DocumentCount",10);
to be
Request.addProperty("DocumentCount","10");
