Simple Android program using .Net web service and Ksoap2

I have given very simple program that uses .Net web service and we display that data in our android program in a text field.


Your .Net web service should return a string like this:


[WebMethod]

public string Test()
{
string sValue = string.Empty;
try
{
sValue = "This is from web service, Yashwanth";
}
catch (Exception ex)
{
sValue = ex.Message.ToString();
}
finally
{
}
return sValue;
}


Create a new android project using eclipse and in your MainActivity class paste the following code. Change the Package name and Activity name of yours.



And your android program:

package com.test.webservice;

import org.ksoap2.serialization.SoapObject;
import org.ksoap2.serialization.SoapPrimitive;

import android.os.Bundle;
import android.app.Activity;
import android.view.Menu;
import android.widget.TextView;
import android.widget.Toast;
import org.ksoap2.SoapEnvelope;
import org.ksoap2.serialization.SoapSerializationEnvelope;
import org.ksoap2.transport.HttpTransportSE;

public class MainActivity extends Activity

{
private static final String SOAP_ACTION = "http://tempuri.org/Test";
private static final String METHOD_NAME = "Test";
private static final String NAMESPACE = "http://tempuri.org/";
private static final String URL = "http://192.168.1.40/Test/Service.asmx";

TextView tv;

@Override
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
tv=(TextView)findViewById(R.id.textView1);
call();
}
public void call()
{
try {
SoapObject request = new SoapObject(NAMESPACE, METHOD_NAME);
SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11);
envelope.dotNet=true;
envelope.setOutputSoapObject(request);
HttpTransportSE androidHttpTransport = new HttpTransportSE(URL);
androidHttpTransport.call(SOAP_ACTION, envelope);
SoapPrimitive response = (SoapPrimitive)envelope.getResponse();
tv.setText(response.toString());
}

catch (Exception e) {
Toast.makeText(MainActivity.this,"Error - " +e.getMessage()
.toString(),Toast.LENGTH_LONG).show();
}}

@Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.main, menu);
return true;
}
}

Your activity_main xml should look like this:

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context=".MainActivity" >

<TextView
android:id="@+id/textView1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerHorizontal="true"
android:layout_centerVertical="true" />
</RelativeLayout>

Your AndroidManifest.xml file:

In AndroidManifest.xml in permission tab add Uses Permission ⇒
Name = android.permission.INTERNET

<?xml version="1.0" encoding="utf-8"?>

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.examp.web"
android:versionCode="1"
android:versionName="1.0" >

<uses-sdk
android:minSdkVersion="8"
android:targetSdkVersion="18" />
<uses-permission android:name="android.permission.INTERNET"/>

<application
android:allowBackup="true"
android:icon="@drawable/ic_launcher"
android:label="@string/app_name"
android:theme="@style/AppTheme" >

<activity android:name="com.examp.web.MainActivity"
android:label="@string/app_name" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</application>
</manifest>


Output:
