I created Java web services and trying to connect with android code.I am getting the service running but android app is showing error in soap object creating for namespace and method name.I did all the changes and everything is correct namespace,method name,URL all is correct.But I don't know what is wrong can anyone help me out...!
My android code is----->
showing error in
-"SoapObject request = new SoapObject(NAMESPACE, METHOD_NAME);"
public class RetailerActivity extends Activity {
private static final String SOAP_ACTION = "urn:training/searchCompanyInfo";
private static final String METHOD_NAME = "searchCompanyInfo";
private static final String NAMESPACE = "urn:training/";
private static final String URL = "http://localhost/attest/CompanyInfoService?wsdl";
/** Called when the activity is first created. */
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
System.out.println(NAMESPACE);
System.out.println(METHOD_NAME);
SoapObject request = new SoapObject(NAMESPACE, METHOD_NAME);
SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11);
envelope.setOutputSoapObject(request);
HttpTransportSE ht = new HttpTransportSE(URL);
try {
ht.call(SOAP_ACTION, envelope);
SoapPrimitive response = (SoapPrimitive)envelope.getResponse();
SoapPrimitive s = response;
String str = s.toString();
String resultArr[] = str.split("&");//Result string will split & store in an array
TextView tv = new TextView(this);
for(int i = 0; i<resultArr.length;i++){
tv.append(resultArr[i]+"\n\n");
}
setContentView(tv);
} catch (Exception e) {
e.printStackTrace();
}
}
}

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.

SOAP web service call from android

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.

I have one simple code for you. Where we have a button and we will be calling helloworld method.
Button Worldmethod;
private static final String SOAP_ACTION1 = "http://tempuri.org/HelloWorld";
private static final String HelloWorldmethod = "HelloWorld";
private static final String NAMESPACE = "http://tempuri.org/";
private static final String URL = "http://192.168.1.5/MobileDemo/Demo.asmx";
#Override
protected void onCreate(Bundle savedInstanceState) {
StrictMode.ThreadPolicy policy = new StrictMode.ThreadPolicy.Builder().permitAll().build();
StrictMode.setThreadPolicy(policy);
super.onCreate(savedInstanceState);
setContentView(R.layout.webservices_layout);
Worldmethod= (Button)findViewById(R.id.Worldmethod);
Worldmethod.setOnClickListener(this);
#Override
public void onClick(View v) {
switch (v.getId()){
case R.id.Worldmethod:
try
{
methodbody= (TextView)findViewById(R.id.methodbody);
SoapObject request1 = new SoapObject(NAMESPACE, HelloWorldmethod);
// add paramaters and values
SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11);
envelope.dotNet = true;
envelope.setOutputSoapObject(request1);
//Web method call
HttpTransportSE androidHttpTransport = new HttpTransportSE(URL);
androidHttpTransport.debug = true;
androidHttpTransport.call(SOAP_ACTION1, envelope);
//get the response
SoapPrimitive result= (SoapPrimitive)envelope.getResponse();
String results = result.toString();
methodbody.setText( ""+results);
}
catch (Exception e)
{
methodbody.setText(e.getMessage());
e.printStackTrace();
}
break;
}
}

How do I use parameters with ksoap2?

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.

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.

XmlPullParser Exception

I'm not able to resolve this error:
org.xmlpull.v1.XmlPullParserException: expected: START_TAG {http://www.w3.org/2001/12/soap-envelope}Envelope (position:START_TAG #1:6 in java.io.InputStreamReader#43e524c8)
I have an Android app which accesses a .NET web service. It passes an int and receives an int as a response. I'm using ksoap2.
I added the permissions to the manifest file also and moreover I included all jar files. However, I'm stuck and I am unable to view which SOAP request I am sending.
My code is:
public class FirstAppUI extends Activity{
private static final String NAMESPACE = "http://tempuri.org/";
private static final String URL =
"http://nautilussoft.biz.whbus12.onlyfordemo.com/staging/litigation/demowebservice.asmx";
private static final String SOAP_ACTION ="http://tempuri.org/GetNumber";
private static final String METHOD_NAME = "GetNumber";
/** Called when the activity is first created. */
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
TextView tv= (TextView)findViewById(R.id.TextView01);
SoapObject request = new SoapObject(NAMESPACE, METHOD_NAME);
request.addProperty("maxbelow", "123");
SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11);
envelope.dotNet= true;
envelope.setOutputSoapObject(request);
HttpTransportSE androidHttpTransport = new HttpTransportSE(URL);
try {
//Toast.makeText(getBaseContext(), "received object", Toast.LENGTH_SHORT).show();
androidHttpTransport.call(SOAP_ACTION, envelope);
Object resultsRequestSOAP = (SoapObject)envelope.getResponse();
//SoapObject resultsRequestSOAP = (SoapObject) envelope.bodyIn;
//Toast.makeText(getBaseContext(), "received object", Toast.LENGTH_SHORT).show();
tv.setText("Received :" + resultsRequestSOAP.toString());
} catch (MalformedURLException e) {
e.printStackTrace();
Log.e("APP", "MalformedURLException while sending\n" + e.getMessage());
tv.setText("Malformedexception"+e);
}
catch(Exception e1)
{
e1.printStackTrace();
tv.setText("exception"+e1);
}
}
}
Thanks in advance.

Give permission to your webserivce folder in IIS or through IIS manager.

please check the weburl you are using.. its case sensitive... even though its working fine in a web browser, you should use the exact name in your code...
