Unable to call Java Webservice from android application - android

I am trying to call java webservice form android application but unable to call it. When I generate WSDL file, SOAPAction showing blank
string(<soap:operation soapAction=""/>) in soap:operation.
My android application code:
public class MainActivity extends Activity {
private static final String SOAP_ACTION = "http://com/add";
private static final String METHOD_NAME = "add";
private static final String NAMESPACE = "http://com/";
private static final String URL = "http://localhost:8080/WebApplication1/demo";
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Button button=(Button)findViewById(R.id.button1);
button.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
SoapObject request = new SoapObject(NAMESPACE, METHOD_NAME);
PropertyInfo pi1 = new PropertyInfo();
pi1.setName("i");
pi1.setValue(3);
pi1.setType(int.class);
request.addProperty(pi1);
PropertyInfo pi2 = new PropertyInfo();
pi2.setName("j");
pi2.setValue(3);
pi2.setType(int.class);
request.addProperty(pi2);
SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(
SoapEnvelope.VER11);
envelope.dotNet = true;
envelope.setOutputSoapObject(request);
// HttpTransportSE androidHttpTransport = new HttpTransportSE(URL);
AndroidHttpTransport androidHttpTransport = new AndroidHttpTransport(URL);
try {
((TextView) findViewById(R.id.textView1)).setText(String
.valueOf("The WebService is about to call"));
androidHttpTransport.call(SOAP_ACTION, envelope);
((TextView) findViewById(R.id.textView1)).setText(String
.valueOf("The WebService call is done"));
SoapPrimitive response = (SoapPrimitive) envelope.getResponse();
((TextView) findViewById(R.id.textView1)).setText(String
.valueOf(response.toString()));
((TextView) findViewById(R.id.textView1)).setText(String
.valueOf("Done"));
} catch (Exception e) {
e.printStackTrace();
Log.e("Err", "Error Says: " + e.toString());
}
}
});
}
}
There is showing an exception network on main thread exception

Because you are calling the web service in your main thread.This must be done in the background using background thread.You can use asyntask for background operations.

cant parse xml using a KSOAP2

I have connected to the asp.net Service using Ksoap2 and it connects fine, but one thing is that i get the response back in XML. Is there anyway i can get it to display in normal text.
This is the code i have used
public class AndroidWebService extends Activity {
/** Called when the activity is first created. */
private static String SOAP_ACTION = "http://tempuri.org/GetHelpDeskCalls";
private static String NAMESPACE = "http://tempuri.org/";
private static String METHOD_NAME = "GetHelpDeskCalls";
static final String URL = "https://198.125.364:8080/AndroidServices/Service1.asmx";
Button getData;
EditText userID;
TextView data;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.helpdesk);
getData = (Button) findViewById(R.id.button1);
userID = (EditText) findViewById(R.id.txtFar);
data = (TextView) findViewById(R.id.textView1);
Thread nT = new Thread() {
#Override
public void run() {
getData.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
SoapObject request = new SoapObject(NAMESPACE,
METHOD_NAME);
request.addProperty("userID", userID.getText()
.toString());
SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(
SoapEnvelope.VER11);
envelope.setOutputSoapObject(request);
envelope.dotNet = true;
envelope.setOutputSoapObject(request);
try {
HttpTransportSE androidHttpTransport = new HttpTransportSE(
URL);
// androidHttpTransport.call(SOAP_ACTION, envelope);
androidHttpTransport.debug = true;
androidHttpTransport.call(SOAP_ACTION, envelope);
final String ss = androidHttpTransport.responseDump;
// final SoapObject response = (SoapObject) envelope
// .getResponse();
runOnUiThread(new Runnable() {
public void run() {
data.setText(ss.toString());
}
});
} catch (Exception e) {
data.setText("Error");
}
}
});
}
};
nT.start();
}
}
There is a neat website called google, it does wonders.
since you seem to be lazy there are 3 basic xml parsing methods you can use
SAX parser,
DOM parser,
XML pull parser

Webservices in android

I am new to android. In my application I tried to call SOAP web services, in that I can't understand what is meant
for(SOAP_Action,OperationName,WSDL_TARGET_NAMESPACE,SOAP_ADDRESS). The following is my full code
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
TextView textView = new TextView(this);
setContentView(textView);
SoapObject request = new SoapObject(WSDL_TARGET_NAMESPACE,
OPERATION_NAME);
SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(
SoapEnvelope.VER11);
envelope.dotNet = true;
System.out.println("subbu="+request);
envelope.setOutputSoapObject(request);
HttpTransportSE httpTransport = new HttpTransportSE(SOAP_ADDRESS);
try
{
httpTransport.call(SOAP_ACTION, envelope);
Object response = envelope.getResponse();
textView.setText(response.toString());
}
catch (Exception exception)
{
textView.setText(exception.toString());
}
}
}
Can anybody explain what thats purpose for. Give some link from which I can get idea.
SOAP_ACTION / NAMESPACE and METHODS can be found in the WSDL file of the target webservice !
Here is a sample code to send a SOAP request to a webservice :
public class SoapRequest {
private static final String SOAP_ACTION = "xxx";
private static final String METHOD_NAME = "xxx";
private static final String NAMESPACE = "xxx";
private static final String URL = "url of the webservice";
public static SoapObject soap() throws IOException, XmlPullParserException {
SoapObject request = new SoapObject (NAMESPACE, METHOD_NAME);
/* Here you can add properties to your requests */
PropertyInfo pi1 = new PropertyInfo();
pi1.name = "xxx";
pi1.type = String.class;
request.addProperty(pi1, "xxx");
SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11);
envelope.setOutputSoapObject(request);
HttpTransportSE androidHttpTransport = new HttpTransportSE(URL);
androidHttpTransport.debug = true;
androidHttpTransport.call(SOAP_ACTION, envelope);
SoapObject soapResult = (SoapObject) envelope.bodyIn;
return soapResult;
}

Android: soap primitive error

I am having some issues with accessing a web service. Getting ClassCastException Error. Consider a scenario that I am trying to access a method of a web-service and the webservice is supposed to return two strings (Lets say String1 and String2). Moreover, I have to provide or pass two parameters (lets say Parameter 1 and Parameter 2 where Parameter 1 should be integer and Parameter 2 should be String) Here is my code
public class MyWebService extends Activity {
private static final String SOAP_ACTION ="http://www.mywebsite.com/myMethod";
private static final String METHOD_NAME = "MyMethod";
private static final String NAMESPACE = "http://www.myNamespace/";
private static final String URL = "http://mysession.com/myservice.asmx?WSDL";
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
try {
SoapObject request = new SoapObject(NAMESPACE, METHOD_NAME);
PropertyInfo pi = new PropertyInfo();
pi.setName("Parameter 1");
pi.setValue(1);
pi.setType(pi.INTEGER_CLASS);
request.addProperty(pi);
PropertyInfo pi2 = new PropertyInfo();
pi2.setName("Parameter 2");
pi2.setValue("Any string");
pi2.setType(pi2.STRING_CLASS);
request.addProperty(pi2);
SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11);
envelope.dotNet=true;
envelope.setOutputSoapObject(request);
HttpTransportSE androidHttpTransport = new HttpTransportSE(URL);
androidHttpTransport.call(SOAP_ACTION, envelope);
SoapObject result=(SoapObject)envelope.getResponse();
String string1=result.getProperty(0).toString();
String string2=result.getProperty(1).toString();
} catch (Exception e) {
e.printStackTrace();
}
}
}
This is the exception I am getting
java.lang.ClassCastException: org.ksoap2.serialization.SoapPrimitive
Can anyone tell me if I am doing something wrong here..
Thanks
Try this,
SoapPrimitive result= (SoapPrimitive)envelope.getResponse();
OR
Object result= (Object)envelope.getResponse();
instead of
SoapObject result=(SoapObject)envelope.getResponse();
Try this:
SoapObject request = new SoapObject(SOAP_NAMESPACE,SOAP_METHOD);
request.addProperty("name", abcd);
request.addProperty("age", 30);

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.
