Android Web Service Access Tutorial

In this post I'm going to illustrate how we can access web service in Android using ksoap2-android project that provides a lightweight and efficient SOAP library for the Android platform.

You can download the jar file from following link;
http://ksoap2-android.googlecode.com/svn/m2-repo/com/google/code/ksoap2-android/ksoap2-android-assembly/2.5.8/ksoap2-android-assembly-2.5.8-jar-with-dependencies.jar

Here is the sample code that illustrate SOAP web service call. I have access a live web service ConvertWeight from http://www.webserviceX.NET/ which convert weight from one unit to another. I have set "envelope.dotNet = true;" in Line 53 since I'm accessing .NET web service. You can comment that line if your web service is not .NET one.
package com.sencide;
 
import org.ksoap2.SoapEnvelope;
import org.ksoap2.serialization.PropertyInfo;
import org.ksoap2.serialization.SoapObject;
import org.ksoap2.serialization.SoapPrimitive;
import org.ksoap2.serialization.SoapSerializationEnvelope;
import org.ksoap2.transport.HttpTransportSE;
 
import android.app.Activity;
import android.os.Bundle;
import android.util.Log;
import android.widget.TextView;
 
public class AndroidWebService extends Activity {
  
    private final String NAMESPACE = "http://www.webserviceX.NET/";
    private final String URL = "http://www.webservicex.net/ConvertWeight.asmx";
    private final String SOAP_ACTION = "http://www.webserviceX.NET/ConvertWeight";
    private final String METHOD_NAME = "ConvertWeight";
 
    /** 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); 
      
        String weight = "3700";
        String fromUnit = "Grams";
        String toUnit = "Kilograms";
      
        PropertyInfo weightProp =new PropertyInfo();
        weightProp.setName("Weight");
        weightProp.setValue(weight);
        weightProp.setType(double.class);
        request.addProperty(weightProp);
         
        PropertyInfo fromProp =new PropertyInfo();
        fromProp.setName("FromUnit");
        fromProp.setValue(fromUnit);
        fromProp.setType(String.class);
        request.addProperty(fromProp);
         
        PropertyInfo toProp =new PropertyInfo();
        toProp.setName("ToUnit");
        toProp.setValue(toUnit);
        toProp.setType(String.class);
        request.addProperty(toProp);
        
        SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11);
        envelope.dotNet = true;
        envelope.setOutputSoapObject(request);
        HttpTransportSE androidHttpTransport = new HttpTransportSE(URL);
 
        try {
            androidHttpTransport.call(SOAP_ACTION, envelope);
            SoapPrimitive response = (SoapPrimitive)envelope.getResponse();
            Log.i("myApp", response.toString());
    
            TextView tv = new TextView(this);
            tv.setText(weight+" "+fromUnit+" equal "+response.toString()+ " "+toUnit);
            setContentView(tv);
 
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
}
You have to add INTERNET permission to AndroidManifest.xml as follows;
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
      package="com.sencide"
      android:versionCode="1"
      android:versionName="1.0">

    <application android:icon="@drawable/icon" android:label="@string/app_name">
        <activity android:name=".AndroidWebService"
                  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>
    
    <uses-permission android:name="android.permission.INTERNET"></uses-permission>
</manifest>
You can download the source code of above project (Password:sara).

I have updated my previous code in the post Android Login Screen Using HttpClient to authenticate users from web service. There I have illustrate how you can start new activity if the login is successful.

You can download the updated source code with sample .NET web service application (Password:sara).

  6. Saranga, your sample app was just what I was looking for. I have a lot of experience with .net web services but I am new to the Android platform. I have looked at a lot of samples that are out there for KSOAP2 but none of them seemed to work as promised. Yours was straight forward and works perfectly. Thanks so much for taking the time to post this. Ken

  9. @ Samuel Limawan,

    First create new folder called "lib" in your project and copy the jar file to that folder.

    Then right click on your project and select Build Path --> Configure Build Path...
    Then go to Libraries tab and click "Add External Jars..." button.
    Then browse the jar file from the created "lib" file. That's it. :)

    Check my following post and there you can see screen-shots.

  10. Hi Saranga,

    Thank you very much for your answer.
    I have one more question :
    How to access secured asp.net webservice that requires user name & password?

    This is an example of secured method.

    _
    _.
    Public Function HelloWorld12() As String.
    If Authentication.Username = "user name" And Authentication.Password = "password" Then.
    Return "Hello World 12".
    Else.
    Return "Access Denied..."
    End If.
    End Function.

    Thanks,
    Samuel

  11. Saranga,

    I was successful running your original sample call that called
    the web service http://www.webservicex.net/ConvertWeight.asmx. However when I try to call the same
    (basically the same) service running on my localhost I get the dreaded "expected START_TAG"... blah blah blah error.

    I saw your other sample, authenticatedUser, was running agaist localhost so I download that sample and got the same error.
    I've tried every hint I can find on the net for solving this problem

    1) I set the service to use local IIS Web Server in visual studio
    2) I tried my local IP address in leiu of localhost
    3) I tried using 10.0.2.2

    None of these work when I try and access a service running on my local server.

    How on earth did you get localhost to work?

    Please check the following post.
    There I have created login screen. Updated code which use web service is available at the end of this post.

    @ Ken,
    Please check following things, make sure you have define these things correctly and these are case sensitive.
    private final String NAMESPACE = "http://tempuri.org/";
    private final String URL = "http://10.0.2.2:50761/Service1.asmx?WSDL";
    final String SOAP_ACTION = "http://tempuri.org/ConvertWeight";
    final String METHOD_NAME = "ConvertWeight";
    If you are getting error please send me your code with web service project. My gmail id is saranga.rathnayake

    1. I have the exact same error as Ken, please could you help me to know which are the fields to put in METHOD_NAME, URL, NAMESPACE and SOAP_ACTION??? My route to the webservice is this one:

      http://caracasfutbolclub.com/esite/images/mobil/webservice/Service1.asmx

      And the method that I want to read is GetNews.

      I am assuming that this is the problem for the expected Start_Tag error. Could be anything else? Thanks in advance Saranga

      Delete
  13. Saranga,

    I am going to email you the AndroidLogin sample instead of the ConvertWeight sample.
    In that one I downloaded your web service code and the android code.
    I was able to get that sample to work when I installed the web service on another machine
    running IIS on my network. You will see a comment in the web service that shows the URL
    I used that worked fine.

    The problem I have is I cannot get the same sample to work when I use my local IIS (localhost or 10.0.2.2).

    I hope you can figure this out. While working with another server is acceptable for me it would make development
    much easier and quicker if I could use localhost when testing.

    Thanks again for your help.

    Ken (KRock).

  35. Hi. I'm trying to access a webservice on my android app. The webservice is running in a Virtual Machine (and working, already made requests using Soap UI). I already developed my code, but i keep getting this error:

    I get exception "org.xmlpull.v1.xmlpullparserexception expected start_tag"

    i think it has to be with the SOAP_ACTION or NAMESPACE, but i already tried all the alternatives that i think that are right.
    Any help on this one plz? Thank you!

    Thank you so much for this post.

    With some other config, I can access my own web service(using SOAP and running on local host of PC) from my Android device with URL "http://ip-address/mywebservice".

    However, if I create a RESTful web service, I can browser it with url "http://localhost/mywebservice" but cant browser with "http://ip-address/mywebservice". And, of course, I can't access this web service from my Android device.

    Do you have any information to help me?

  62. Hi Saranga,

    I have been trying to learn about calling web services from android and found your tutorial online.
    I have imported it and getting the following error for each of the methods below:

    weightProp.setName("Weight");
    weightProp.setValue(weight);
    weightProp.setType(double.class);
    request.addProperty(weightProp);



    "The method setName(String) is undefined for the type weightProp"
    Is there something missing? Do I need to have an extra class, or how do I define these methods?

    Could you please please help me??

    Thank you soo much.

    One solution might be to rename the "lib" folder in the original uploaded project to "libs". It worked for me to get rid of the original crashings

  72. Saranga, I have a question. I was able to make the application run, then I run the web service, I checked on the method in the .NET project, and is comparing user and pass with user=saranga, and pass=saranga. I type that on the Android app but get always "LOGIN FAILED" message. Any idea what could be causing this?
    Thanks
    Miguel

  79. Hello Saranga
    your post is very useful, but I have a small problem
    I am new to Android platform.

    My web service is accessible via a web application. Net.
    but I can not get a response via Andriod.
    When I call 'androidHttpTransport.call (Exec_SOAP_ACTION, envelope);'
    execution proceeds directly into the 'catch'

    have you an idea about the origin to the problem.
    Thx ...
