How to communicate WCF webservices in android applications

- First you have to create wcf webserices, then you have defines some necessary thing to communicate with wcf.

You have to recognize the following in your wsdl file:

Method Name and Soap Action:

Namespace:

URL:

Download ksoap 2 and import in libs folder in android:
           

The different version of these files are available at http://code.google.com/p/ksoap2-android/source/browse/#svn/m2-repo/com/google/code/ksoap2-android/ksoap2-android-assembly/

To download a file from there, right click on "View raw file" and select "Save Link as" (this label differs for different browsers) and you will get the full jar downloaded.

The latest release artifact would be available at

http://code.google.com/p/ksoap2-android/source/browse/m2-repo/com/google/code/ksoap2-android/ksoap2-android-assembly/3.2.0/ksoap2-android-assembly-3.2.0-jar-with-dependencies.jar

with a direct download url of

http://ksoap2-android.googlecode.com/svn/m2-repo/com/google/code/ksoap2-android/ksoap2-android-assembly/3.2.0/ksoap2-android-assembly-3.2.0-jar-with-dependencies.jar

Now you have to defines following java code in your android application:

import org.ksoap2.SoapEnvelope;
import org.ksoap2.serialization.SoapObject;
import org.ksoap2.serialization.SoapPrimitive;
import org.ksoap2.serialization.SoapSerializationEnvelope;
import org.ksoap2.transport.AndroidHttpTransport;
import android.app.Activity;
import android.app.ProgressDialog;
import android.os.AsyncTask;
import android.os.Bundle;
import android.widget.TextView;

public class Test extends Activity {

public class SoapTask extends AsyncTask<Void, Void, Void> {
private final ProgressDialog dialog = new ProgressDialog(Test.this);
protected void onPreExecute() {

this.dialog.setMessage("Checking in...");
this.dialog.show();

}

@Override
protected Void doInBackground(Void... arg0) {
try{
WebServiceCallExample();
}catch (Exception e){
e.printStackTrace();
}
return null;
}

protected void onPostExecute(Void result) {
TextView tv = (TextView) findViewById(R.id.Result);
tv.setText(test_string);
if (this.dialog.isShowing()){
this.dialog.dismiss();
}
}

}

private String test_string;

@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.test);
new SoapTask().execute();
}

@SuppressWarnings("deprecation")
public void WebServiceCallExample() {
final String NAMESPACE = "http://tempuri.org/";
final String URL = "http://yoururl.com/testService.svc";
final String METHOD_NAME = "SayHello";
final String SOAP_ACTION = "http://tempuri.org/IWFPService/SayHello";

SoapObject Request = new SoapObject(NAMESPACE, METHOD_NAME);

/* Set the web service envelope */
SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11);
envelope.dotNet = true;
envelope.setOutputSoapObject(Request);
System.out.println("Request::" + Request.toString());

AndroidHttpTransport androidHttpTransport = new AndroidHttpTransport(URL);
try{
androidHttpTransport.call(SOAP_ACTION, envelope);
//SoapObject response = (SoapObject) envelope.getResponse();
SoapPrimitive sp = (SoapPrimitive) envelope.getResponse();

SoapObject resultsRequestSOAP = (SoapObject) envelope.bodyIn;
System.out.println("Response::" + resultsRequestSOAP.toString());
test_string = sp.toString();
}catch (Exception e){
e.printStackTrace();
}
}
}


test.xml layout file here:

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:focusable="true"
    android:focusableInTouchMode="true"
    android:orientation="vertical" >


    <TextView
        android:id="@+id/Result"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_marginLeft="7dip"
        android:layout_marginRight="7dip"
        android:gravity="fill_vertical|fill_horizontal"
        android:layout_gravity="center_horizontal"
         android:textSize="24dip" android:text="test"
        android:textStyle="bold" >
    </TextView>

</LinearLayout>
