Im getting single data from web service using SOAP in android and displayed well.But when i need to retrieve multiple set of values from web services..How could i do that?For ex.from a webservice.,im getting 10 set of student records with fields stu.Name,stuRegno.,stuAge.After getting response of this.,i need to parse it to stored into local db with corresponding field names.How could i do that?
My code:
public class Main extends Activity {
private static final String METHOD_NAME = "TopGoalScorers";
private static final String SOAP_ACTION = "http://footballpool.dataaccess.eu/data/TopGoalScorers";
private static final String NAMESPACE = "http://footballpool.dataaccess.eu";
private static final String URL = "http://footballpool.dataaccess.eu/data/info.wso?WSDL";
//Called when the activity is first created.
#Override
public void onCreate(Bundle icicle) {
super.onCreate(icicle);
setContentView(R.layout.main);
//Buttons deaktiviert alles automatisch
SoapObject request = new SoapObject(NAMESPACE, METHOD_NAME);
request.addProperty("iTopN", 3);// username von Preferences abgeholt
//request.addProperty("intB", 4);
SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11);
Toast.makeText(getApplicationContext(), request.toString(), Toast.LENGTH_LONG).show();
envelope.setOutputSoapObject(request);
AndroidHttpTransport androidHttpTransport = new AndroidHttpTransport (URL);
try {
androidHttpTransport.call(SOAP_ACTION, envelope);
//Parse Response
SoapObject resultsRequestSOAP = (SoapObject) envelope.getResponse();
String xy = resultsRequestSOAP.getProperty(0).toString();
((TextView)findViewById(R.id.lblStatus)).setText(xy);
} catch(Exception E) {
((TextView)findViewById(R.id.lblStatus)).setText("ERROR:" + E.getClass().getName() + ": " + E.getMessage());
}
}
}
I don't understand what is your problem. You need to convert resultsRequestSOAP to appropriate data format(for example String) and parse it(for example through SAX) and in your parser collect all data in a container(for example List).

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

tv.append(resultArr[i]+"\n\n");
}
setContentView(tv);
} catch (Exception e) {

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.
The above image is just adding two values and displaying the result on the below textview.
But i need to show that answer on the first tab(ie.Tab_1) of tabhost on next screen.
How to do this?
.java class
public class Demo_webserviceActivity extends Activity
{
/** Called when the activity is first created. */
private static String NAMESPACE = "http://tempuri.org/";
private static String METHOD_NAME = "FahrenheitToCelsius";
private static String SOAP_ACTION = "http://tempuri.org/FahrenheitToCelsius";
private static String URL = "http://www.w3schools.com/webservices/tempconvert.asmx?WSDL";
Button btnFar;
EditText txtFar;
#Override
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
btnFar = (Button)findViewById(R.id.btnFar);
txtFar = (EditText)findViewById(R.id.txtFar);
btnFar.setOnClickListener(new View.OnClickListener()
{
public void onClick(View v)
{
String b;
//Initialize soap request + add parameters
SoapObject request = new SoapObject(NAMESPACE, METHOD_NAME);
//Use this to add parameters
request.addProperty("Fahrenheit",txtFar.getText().toString());
//Declare the version of the SOAP request
SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11);
envelope.setOutputSoapObject(request);
envelope.dotNet = true;
try
{
HttpTransportSE androidHttpTransport = new HttpTransportSE(URL);
//this is the actual part that will call the webservice
androidHttpTransport.call(SOAP_ACTION, envelope);
// Get the SoapResult from the envelope body.
SoapPrimitive result = (SoapPrimitive)envelope.getResponse();
if(result != null)
{
//Get the first property and change the label text
b = result.toString();
Intent i = new Intent(getApplicationContext(),Activity2.class);
i.putExtra("gotonextpage", b.toString());
startActivity(i);
}
else
{
Toast.makeText(getApplicationContext(), "No Response",Toast.LENGTH_SHORT).show();
}
}
catch (Exception e)
{
e.printStackTrace();
}
}
});
}
}
NOTE : This source is actually consuming a webservice from android and showing the result by SOAP method
Thanks a lot.
You can use Shared preferences to store values, then you can access it in any activity of your project:

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.
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...
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.
