How do I use parameters with ksoap2? - android

I have created a web service to test passing parameters via ksoap2. I thought it seemed like a pretty simple process, but I'm apparently missing something simple. The web service does nothing more than return the integer that is passed to it. When I execute the code below it returns the number 0 instead of 1.
private static String SOAP_ACTION = "http://tempuri.org/TestParams";
private static String NAMESPACE = "http://tempuri.org/";
private static String METHOD_NAME = "TestParams";
private static String URL = "http://services.lockrem.com/WebService.asmx?WSDL";
/** Called when the activity is first created. */
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
SoapObject request = new SoapObject(NAMESPACE, METHOD_NAME);
request.addProperty("RoundId", 1);
SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11);
envelope.setOutputSoapObject(request);
HttpTransportSE androidHttpTransport = new HttpTransportSE(URL);
try {
androidHttpTransport.call(SOAP_ACTION, envelope);
} catch (Exception e) {
e.printStackTrace();
}
SoapObject result = (SoapObject)envelope.bodyIn;
Note: I have tested this using a .net web page and it returns the number 1 as expected. The web service is not the issue here.
Here is the web service.
[WebMethod]
public int TestParams(int RoundId)
{
return RoundId;
}
Thank you for any help.

Disclaimer: Whenever I try to talk to a .NET webservice using kSoap2, I usually end up doing a lot of fiddling. And I mean that literally: I setup a windows machine with Fiddler2 and use that as a proxy for both the failing request and a working reference request, so I can actually see what's going wrong. I strongly advise doing something similar as soon as you try to do something non-trivial.
That said, in your case, it might be enough to do
envelope.dotNet = true;

Try removing the WSDL at the end
private static String URL = "http://services.lockrem.com/WebService.asmx";
In addition try using this to get the response:
Object response = envelope.getResponse();
instead of SoapObject result = (SoapObject)envelope.bodyIn;
EDITED
This works:
public class MainActivity extends Activity {
private static String NAMESPACE = "http://tempuri.org/";
private static String METHOD_NAME = "TestParams";
private static String URL = "http://services.lockrem.com/WebService.asmx";
private TextView tv;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
tv = (TextView)findViewById(R.id.tv);
HttpTransportSE transport = new HttpTransportSE(URL);
SoapObject request = new SoapObject(NAMESPACE, METHOD_NAME);
request.addProperty("RoundId", 1);
SoapSerializationEnvelope envelope =
new SoapSerializationEnvelope(SoapEnvelope.VER11);
envelope.dotNet = true;
envelope.setOutputSoapObject(request);
try {
transport.call(NAMESPACE + METHOD_NAME, envelope);
Object response = envelope.getResponse();
tv.setText(response.toString());
} catch (Exception e) {
e.printStackTrace();
}
}
}
Hope it helps.

In Android, You cannot perform network operation on the main thread, You need to execute your soap request in a background thread. Please read up on AsyncTask.

Could anyone please help in processing the SOAP request and response from an android application.
I have followed the tutorial at
http://www.c-sharpcorner.com/UploadFile/88b6e5/how-to-call-web-service-in-android-using-soap/
But when I run the application, it exits prematurely with the error
Unfortunately, has stopped.
I am running it in an emulator.
Can anyone please explain what I might be missing. Any example source code will be very useful.

Thanks for any help
Since your code works with several other web services. I think you have only changed the URL,SOAP Action and Method. So please check weather the response contain a popper SOAP message. To check that you can something like TCPMon in between the communication.

How to add header,username,password sharepoint webservice using ksoap in android

I am writing an Android application that will use the getlistitems() method of the lists.amx service in sharepoint 2010. I am using ksoap2-android to handle my soap messages. When I try to authenticate I get an xmlpullparser exception expected START_TAG... Why will the following code not authenticate to the sharepoint server?
private static final String SOAP_ACTION = "http://schemas.microsoft.com/sharepoint/soap/GetListItems";
private static final String METHOD_NAME = "GetListItems";
private static final String NAMESPACE = "http://schemas.microsoft.com/sharepoint/soap/";
private static final String URL = "http://www.domain.com/tr-TR/_vti_bin/Lists.asmx";
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
TextView tv=(TextView)findViewById(R.id.tve);
SoapObject request = new SoapObject(NAMESPACE, METHOD_NAME);
request.addProperty("listName", "Haberler");
request.addProperty("viewName", null);
request.addProperty("query", null);
request.addProperty("viewFields", null);
request.addProperty("rowLimit", "30");
request.addProperty("queryOptions", null);
request.addProperty("webID",null);
SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(
SoapEnvelope.VER11);
envelope.dotNet = true;
envelope.setOutputSoapObject(request);
// envelope.headerOut=new Element[1];
// envelope.headerOut[0]=buildAuthHeader();
String authentication = android.util.Base64.encodeToString("myusername:mypassword".getBytes(), android.util.Base64.NO_WRAP);
List<HeaderProperty> headers = new ArrayList<HeaderProperty>();
headers.add(new HeaderProperty("X-FORMS_BASED_AUTH_ACCEPTED","f" +authentication));
HttpTransportSE androidHttpTransport = new HttpTransportSE(URL);
androidHttpTransport.debug = true;
try {
androidHttpTransport.call(SOAP_ACTION, envelope,headers);
SoapObject response = (SoapObject) envelope.getResponse();
tv.setText(response.toString());
Log.e("SONUC",response.toString());
} catch (Exception e1) {
e1.printStackTrace();
}
}
Don't send null values. Instead, add all the values and then try sending it.
Try to use NtlmTransport instead of HttpTransportSE. MayBe it works for you.

How to call a .NET Webservice from Android using KSOAP2?

I have a problem while calling a webservice. I have a .NET web service on the server, and I am using KSOAP2 (ksoap2-j2se-full-2.1.2) in Android. While running the program I got an runtime exception like "org.ksoap2.serialization.SoapPrimitive". What should I do?
Here is my code.
package projects.ksoap2sample;
import org.ksoap2.SoapEnvelope;
import org.ksoap2.serialization.SoapObject;
import org.ksoap2.serialization.SoapSerializationEnvelope;
import org.ksoap2.transport.HttpTransportSE;
import android.app.*;
import android.os.*;
import android.widget.TextView;
public class ksoap2sample extends Activity {
/** Called when the activity is first created. */
private static final String SOAP_ACTION = "http://tempuri.org/HelloWorld";
private static final String METHOD_NAME = "HelloWorld";
private static final String NAMESPACE = "http://tempuri.org/";
private static final String URL = "http://192.168.1.19/TestWeb/WebService.asmx";
TextView tv;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
tv=(TextView)findViewById(R.id.text1);
try {
SoapObject request = new SoapObject(NAMESPACE, METHOD_NAME);
//request.addProperty("prop1", "myprop");
SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11);
envelope.dotNet=true;
envelope.setOutputSoapObject(request);
HttpTransportSE androidHttpTransport = new HttpTransportSE(URL);
androidHttpTransport.call(SOAP_ACTION, envelope);
Object result = (Object)envelope.getResponse();
String[] results = (String[]) result;
tv.setText( ""+results[0]);
}
catch (Exception e) {
tv.setText(e.getMessage());
}
}
}
It's very simple. You are getting the result into an Object which is a primitive one.
Your code:
Object result = (Object)envelope.getResponse();
Correct code:
SoapObject result=(SoapObject)envelope.getResponse();
//To get the data.
String resultData=result.getProperty(0).toString();
// 0 is the first object of data.
I think this should definitely work.
How does your .NET Webservice look like?
I had the same effect using ksoap 2.3 from code.google.com. I followed the tutorial on The Code Project (which is great BTW.)
And everytime I used
Integer result = (Integer)envelope.getResponse();
to get the result of a my webservice (regardless of the type, I tried Object, String, int) I ran into the org.ksoap2.serialization.SoapPrimitive exception.
I found a solution (workaround). The first thing I had to do was to remove the "SoapRpcMethod() attribute from my webservice methods.
[SoapRpcMethod(), WebMethod]
public Object GetInteger1(int i)
{
// android device will throw exception
return 0;
}
[WebMethod]
public Object GetInteger2(int i)
{
// android device will get the value
return 0;
}
Then I changed my Android code to:
SoapPrimitive result = (SoapPrimitive)envelope.getResponse();
However, I get a SoapPrimitive object, which has a "value" filed that is private. Luckily the value is passed through the toString() method, so I use Integer.parseInt(result.toString()) to get my value, which is enough for me, because I don't have any complex types that I need to get from my Web service.
Here is the full source:
private static final String SOAP_ACTION = "http://tempuri.org/GetInteger2";
private static final String METHOD_NAME = "GetInteger2";
private static final String NAMESPACE = "http://tempuri.org/";
private static final String URL = "http://10.0.2.2:4711/Service1.asmx";
public int GetInteger2() throws IOException, XmlPullParserException {
SoapObject request = new SoapObject(NAMESPACE, METHOD_NAME);
PropertyInfo pi = new PropertyInfo();
pi.setName("i");
pi.setValue(123);
request.addProperty(pi);
SoapSerializationEnvelope envelope =
new SoapSerializationEnvelope(SoapEnvelope.VER11);
envelope.dotNet = true;
envelope.setOutputSoapObject(request);
AndroidHttpTransport androidHttpTransport = new AndroidHttpTransport(URL);
androidHttpTransport.call(SOAP_ACTION, envelope);
SoapPrimitive result = (SoapPrimitive)envelope.getResponse();
return Integer.parseInt(result.toString());
}
Typecast the envelope to SoapPrimitive:
SoapPrimitive result = (SoapPrimitive)envelope.getResponse();
String strRes = result.toString();
and it will work.
You can Use below code to call the web service and get response .Make sure that your Web Service return the response in Data Table Format..This code help you if you using data from SQL Server database .If you you using MYSQL you need to change one thing just replace word NewDataSet from sentence obj2=(SoapObject) obj1.getProperty("NewDataSet"); by DocumentElement
private static final String NAMESPACE = "http://tempuri.org/";
private static final String URL = "http://localhost/Web_Service.asmx?"; // you can use IP address instead of localhost
private static final String METHOD_NAME = "Function_Name";
private static final String SOAP_ACTION = NAMESPACE + METHOD_NAME;
SoapObject request = new SoapObject(NAMESPACE, METHOD_NAME);
request.addProperty("parm_name", prm_value); // Parameter for Method
SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11);
envelope.dotNet = true;
envelope.setOutputSoapObject(request);
HttpTransportSE androidHttpTransport = new HttpTransportSE(URL);
try {
androidHttpTransport.call(SOAP_ACTION, envelope); //call the eb service Method
} catch (Exception e) {
e.printStackTrace();
} //Next task is to get Response and format that response
SoapObject obj, obj1, obj2, obj3;
obj = (SoapObject) envelope.getResponse();
obj1 = (SoapObject) obj.getProperty("diffgram");
obj2 = (SoapObject) obj1.getProperty("NewDataSet");
for (int i = 0; i < obj2.getPropertyCount(); i++) //the method getPropertyCount() return the number of rows
{
obj3 = (SoapObject) obj2.getProperty(i);
obj3.getProperty(0).toString(); //value of column 1
obj3.getProperty(1).toString(); //value of column 2
//like that you will get value from each column
}
If you have any problem regarding this you can write me..
If more than one result is expected, then the getResponse() method will return a Vector containing the various responses.
In which case the offending code becomes:
Object result = envelope.getResponse();
// treat result as a vector
String resultText = null;
if (result instanceof Vector)
{
SoapPrimitive element0 = (SoapPrimitive)((Vector) result).elementAt(0);
resultText = element0.toString();
}
tv.setText(resultText);
Answer based on the ksoap2-android (mosabua fork)
I think you can't call
androidHttpTransport.call(SOAP_ACTION, envelope);
on main Thread.
Network operations should be done on different Thread.
Create another Thread or AsyncTask to call the method.
