Introduction
In this tutorial, we will learn how to call a Web Service using SOAP (Simple Object Access Protocol).
Prerequisites
Web Service, SOAP envelope, WSDL (Web Service Definition Language)
What is SOAP?
SOAP is a protocol specification for exchanging structured information in the implementation of Web Services in computer networks. It relies on Extensible Markup Language (XML) for its message format and usually relies on other Application Layer protocols, most notably Hypertext Transfer Protocol (HTTP) and Simple Mail Transfer Protocol (SMTP), for message negotiation and transmission. The following is the structure of the SOAP Envelope:
Step 1
First, create a "New Android Project". Name it "WebServiceDemo" like below.
Step 2
Now right-click on your "WebServiceDemo" project and select "New -> Folder"
Now, give it a name it "lib". We need to add a SOAP library into this directory.
Step 3
Now download the attached library named "ksoap2-android-assembly-2.6.0-jar-with-dependencies.jar". Copy that file and paste it into the "lib" directory.
After copying, do the following steps:
- Right-click on the project.
- Go "Build Path -> Configure Build Path"
- Now, click on "Add Jars" and select the ".jar" file from the "project -> lib" directory.
- Click on "Ok" to finish the procedure of adding the library to the Android application.
Step 4
Next, we need to create a layout of a screen. To do so, go to "WebServiceDemo -> res -> layout -> main.xml"
Open this XML file in editing mode, and place the below code.
Main.xml
- <?xml version="1.0" encoding="utf-8"?>
- <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
- android:layout_width="match_parent"
- android:layout_height="match_parent"
- android:orientation="vertical" >
- <TextView
- android:id="@+id/textView1"
- android:layout_width="wrap_content"
- android:layout_height="wrap_content"
- android:text="Fahrenheit"
- android:textAppearance="?android:attr/textAppearanceLarge" />
- <EditText
- android:id="@+id/txtFar"
- android:layout_width="match_parent"
- android:layout_height="wrap_content" >
- <requestFocus />
- </EditText>
- <TextView
- android:id="@+id/textView2"
- android:layout_width="wrap_content"
- android:layout_height="wrap_content"
- android:text="Celsius"
- android:textAppearance="?android:attr/textAppearanceLarge" />
- <EditText
- android:id="@+id/txtCel"
- android:layout_width="match_parent"
- android:layout_height="wrap_content" />
- <LinearLayout
- android:id="@+id/linearLayout1"
- android:layout_width="match_parent"
- android:layout_height="wrap_content" >
- <Button
- android:id="@+id/btnFar"
- android:layout_width="wrap_content"
- android:layout_height="wrap_content"
- android:layout_weight="0.5"
- android:text="Convert To Celsius" />
- <Button
- android:id="@+id/btnCel"
- android:layout_width="wrap_content"
- android:layout_height="wrap_content"
- android:layout_weight="0.5"
- android:text="Convert To Fahrenheit" />
- </LinearLayout>
- <Button
- android:id="@+id/btnClear"
- android:layout_width="match_parent"
- android:layout_height="wrap_content"
- android:text="Clear" />
- </LinearLayout>
This will create simple
following screen.
Step 5
Now, find out any Web Service, make sure that you can view its WSDL file by writing "?wsdl" after that address.
http://www.w3schools.com/webservices/tempconvert.asmx?WSDL".
You are now done with the Web Service part from the internet. Now you need to extend some portion of the WSDL file. Open the first link in your browser, it will display 2 conversions for you:
-
CelsiusToFahrenheit
-
FahrenheitToCelsius
Select anyone of them, and you will see following screen:
For CelsiusToFahrenheit
-
-
-
METHOD_NAME = "CelsiusToFahrenheit";
-
For FahrenheitToCelsius
-
-
-
METHOD_NAME = " FahrenheitToCelsius ";
-
Step 6
You need to understand some classes before proceeding to use a Web Service.
-
SoapObject (
A simple dynamic object that can be used to build SOAP calls without implementing KvmSerializable. Essentially, this is what goes inside the body of a SOAP envelope - it is the direct subelement of the body and all further sub-elements. Instead of this class, custom classes can be used if they implement the KvmSerializable interface.
ConstructorSoapObject (java.lang.String namespace, java.lang.String method)
-
SoapSerializationEnvelope
This class extends the SoapEnvelope with Soap Serialization functionality.
Constructor
SoapSerializationEnvelope (int version)
Fields
|
Type
|
Field
|
Description
|
|
boolean
|
dotNet
|
Set this variable to true for compatibility with what seems to be the default encoding for .Net-Services.
|
Methods
|
Return Type
|
Method Name
|
Description
|
|
void
|
setOutputSoapObject(java.lang.Object soapObject)
|
Assigns the object to the envelope as the outbound message for the soap call.
|
-
HttpTransportSE (org.ksoap2.transport.HttpTransportSE)A J2SE based HTTP transport layer.
Constructor
HttpTransportSE(java.lang.String url)
Method
|
Return Type
|
Method
|
Description
|
|
void
|
call(java.lang.String SoapAction, SoapEnvelope envelope)
|
set the desired soapAction header field
|
Step 7
Open your "WebServiceDemo -> src -> WebServiceDemoActivity.java" file and enterr following code.
WebServiceDemoActivity.java
- import org.ksoap2.SoapEnvelope;
- import org.ksoap2.serialization.SoapObject;
- import org.ksoap2.serialization.SoapSerializationEnvelope;
- import org.ksoap2.transport.HttpTransportSE;
- import android.app.Activity;
- import android.os.Bundle;
- import android.view.View;
- import android.widget.Button;
- import android.widget.EditText;
- import android.widget.Toast;
- public class WebServiceDemoActivity extends Activity
- {
-
- private static String SOAP_ACTION1 = "http://tempuri.org/FahrenheitToCelsius";
- private static String SOAP_ACTION2 = "http://tempuri.org/CelsiusToFahrenheit";
- private static String NAMESPACE = "http://tempuri.org/";
- private static String METHOD_NAME1 = "FahrenheitToCelsius";
- private static String METHOD_NAME2 = "CelsiusToFahrenheit";
- private static String URL = "http://www.w3schools.com/webservices/tempconvert.asmx?WSDL";
- Button btnFar,btnCel,btnClear;
- EditText txtFar,txtCel;
- @Override
- public void onCreate(Bundle savedInstanceState)
- {
- super.onCreate(savedInstanceState);
- setContentView(R.layout.main);
- btnFar = (Button)findViewById(R.id.btnFar);
- btnCel = (Button)findViewById(R.id.btnCel);
- btnClear = (Button)findViewById(R.id.btnClear);
- txtFar = (EditText)findViewById(R.id.txtFar);
- txtCel = (EditText)findViewById(R.id.txtCel);
- btnFar.setOnClickListener(new View.OnClickListener()
- {
- @Override
- public void onClick(View v)
- {
-
- SoapObject request = new SoapObject(NAMESPACE, METHOD_NAME1);
-
- request.addProperty("Fahrenheit",txtFar.getText().toString());
-
- SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11);
- envelope.setOutputSoapObject(request);
- envelope.dotNet = true;
- try {
- HttpTransportSE androidHttpTransport = new HttpTransportSE(URL);
-
- androidHttpTransport.call(SOAP_ACTION1, envelope);
-
- SoapObject result = (SoapObject)envelope.bodyIn;
- if(result != null)
- {
-
- txtCel.setText(result.getProperty(0).toString());
- }
- else
- {
- Toast.makeText(getApplicationContext(), "No Response",Toast.LENGTH_LONG).show();
- }
- } catch (Exception e) {
- e.printStackTrace();
- }
- }
-
- });
- btnCel.setOnClickListener(new View.OnClickListener()
- {
- @Override
- public void onClick(View v)
- {
-
- SoapObject request = new SoapObject(NAMESPACE, METHOD_NAME2);
-
- request.addProperty("Celsius",txtCel.getText().toString());
-
- SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11);
- envelope.setOutputSoapObject(request);
- envelope.dotNet = true;
- try {
- HttpTransportSE androidHttpTransport = new HttpTransportSE(URL);
-
- androidHttpTransport.call(SOAP_ACTION2, envelope);
-
- SoapObject result = (SoapObject)envelope.bodyIn;
- if(result != null)
- {
-
- txtFar.setText(result.getProperty(0).toString());
- }
- else
- {
- Toast.makeText(getApplicationContext(), "No Response",Toast.LENGTH_LONG).show();
- }
- } catch (Exception e) {
- e.printStackTrace();
- }
- }
- });
- btnClear.setOnClickListener(new View.OnClickListener()
- {
- @Override
- public void onClick(View v)
- {
- txtCel.setText("");
- txtFar.setText("");
- }
- });
- }
- }
Step 8
Now, open your "WebServiceDemo -> android.manifest" file. Add the following line before the <application> tag:
<uses-permission android:name="android.permission.INTERNET" />
This will allow the application to use the internet.
Step 9
Run your application in the Android Cell. You will get the following outcome:
NoteIn the emulator, we need to fix a proxy, so try the application in an Android Cell.
Summary
In this brief tutorial, we learned about Web Services, SOAP envelopes, WSDL files, HTTP transport, and how to use them in an Android application.

Jay YosiPosted Feb 7, 2017, 2:28 PM
For those who visited this site lately make sure that you update the URL, namespace, SoapAction, as Akhil Nair put it. Also make sure you use either thread or AsyncTask class to implement the process.
Akhil NairPosted Jan 27, 2017, 12:25 AM
Works like a charm!!!!................use this...........final private String URL = "http://www.w3schools.com/xml/tempconvert.asmx";private static String SOAP_ACTION1 = "http://www.w3schools.com/xml/FahrenheitToCelsius"; private static String NAMESPACE = "http://www.w3schools.com/xml/"; private static String METHOD_NAME1 = "FahrenheitToCelsius";

You can check like if(envelope.bodyIn instanceof SoapFault){//Fault is returned from soap service}else{//this is SoapObject}
Sumit GuhaPosted Jun 17, 2014, 5:23 AM
Not able to run this sample. Please check error log as : 06-17 14:44:03.303: W/System.err(18244): java.lang.ClassCastException: org.ksoap2.SoapFault cannot be cast to org.ksoap2.serialization.SoapObject Please help me to reolve it..

hi, it was very useful, as you commented before it depends if API is below or above 15... So it worked on my emulator which is below 15 but didn't work on cell which is above 15... What would be the reason for that? Do i need some changes on dependencies? thanks

@salman, which API level you are using??? if its above 15, then you need to add "Android Dependencies" otherwise you need to check for "Android References".

Hello Chintan, nice tutorial. Helped me much. I have a further question. For example you want to send a list of "Fahrenheit" values to this service and want to use the responses for each value. Have you an idea how to handle this? For me it´s difficult to send values in a loop. Maybe you have an idea? Thank you.

Hi Abbas... solution for this is don't store your json stream inside memory. instead store it in a "file" inside cache directory. and after completion, just read that file and parse it.

The namespace defines the Envelope as a SOAP Envelope. If you do like to learn SOAP from scratch, "http://www.w3schools.com/soap/soap_intro.asp" site will help you.

Hi, I searched for proxy settings in emulator, and i found that you need to give proxy in your "RunConfiguration" which is "Your Project"->Run As-> Run Configuration -> Target -> Additional Emulator Command Line Argument Options. In this field, you need to pass argument like following. Syntax -------- -http-proxy <ip>:<port> Example --------- -http-proxy http://10.10.136.103:8080 Above are my settings to access Internet. This will solve issue of connecting emulator to Internet and you can also access internet also. Thanks

Hi Chintan, very nice and simple tutorial. I have looked at many before and was a bit confused by some. I am doing the uni project and will need to access some web services. At the moment I can only test it on emulator, will have a phone hopufully next week. I was wondering if you could explain what you mean by fixing proxy, cause I think this is what stops me from getting other examples to work. Thanks alot.

Chintan RathodPosted Jul 21, 2012, 1:17 PM
Solution: 1) When your activity is in "running" mode (you can view your activity on screen), and you are trying to recall that activity one more time, it will fire that "Activity not started, its current task has been brought to the front" 2) Most important thing is that, web service call and other internet "http" calls we can't do from emulator. because it has some limitation of streaming and proxies. Thought you can set proxy in your emulator, you are not able to perfectly call http. even though your internet path is right, it will not download that file. the only way to overcome this is to try this application in actual android cell.

Thanks for your answers!
Chintan RathodPosted Jul 11, 2012, 4:05 AM
yes you can use web service by building wsdl file from java file. and you can make it simple by just calling is soap methods....you can find free plug ins in eclipse which will help you to build wsdl files...
JohnPosted Jul 11, 2012, 2:47 AM
For your experience, which is the best solution to invoke Java methods (on android app) from Java server (on PC)? (e.g. like RPC used between C++ & Java)
Chintan RathodPosted Jul 11, 2012, 1:50 AM
yes.. you could. And though you don't have a device, no problem. you can make some changes in emulator to connect it with internet, as our device has "Wireless Connection Settings". If you are successful to connect your emulator with internet, it will give you output like a device. So, carry on.
JohnPosted Jul 10, 2012, 10:59 AM
Thanks for your reply! So, unfortunately, I haven't a device to test it. I'm studing for a real time application (Java server (on PC) and Android app). You think that the use of web service could be a good solution?
Chintan RathodPosted Jul 10, 2012, 10:46 AM
hi... thanks.. there is free appliation available like "Proxy Setting" but still some problem facing for web service calling in emulators. So its batter to test it in real device.
JohnPosted Jul 10, 2012, 10:41 AM
Good work!!! How can I fix a proxy to emulate this app on emulator?
Chintan RathodPosted Jul 6, 2012, 8:24 AM
Have you read all commments? If you read, you will be going to knew that application is running successfully. I am not kidding. I am an android application developer. So follow the process, you will definitely get output.
rupesh munotPosted Jul 6, 2012, 7:24 AM
it's not working.. are u kidding with us?
Zacharia CherianPosted Jun 18, 2012, 4:19 AM
Good work...
gracePosted May 31, 2012, 3:31 AM
sure. i'll check on them. maybe i need to read lots of articles before creating apps first. thanks for your time sir! :)
Chintan RathodPosted May 31, 2012, 3:24 AM
my pleasure grace ... i also posted other articles, which are initial level tutorials, you can also see them. :-)
gracePosted May 31, 2012, 3:16 AM
hehe. yes! i really wanted to know more. i have a lot of questions. it shows there are lot of things i need to learn first. i'm glad i landed here in your article. thank you sir!
Chintan RathodPosted May 31, 2012, 3:09 AM
yes.. android provide facility to direct run your application in cell. And if you do have any query, there will be no any last question for me... it's my pleasure if you ask me.
gracePosted May 31, 2012, 2:57 AM
wow. i didn't know that. thanks sir! last question. do you also run your projects in your android cell? :)
Chintan RathodPosted May 31, 2012, 2:42 AM
yes, what you understood is right...emulator has some limitations as like demo and real.
gracePosted May 31, 2012, 2:37 AM
okay. so i need to really install it with my phone and not rely on the emulator? is that what you mean?
Chintan RathodPosted May 31, 2012, 2:33 AM
Hm.. I know what is problem with emulator. Emulator has some setting of ports and proxies. For that you need to install some application which will set those settings and allow you to run application. If you want to check now, you can check. You can't access your internet through your emulator, thought you have provided permission. You just need to see the web service, as shown in figure ( with red annotation ) , and need to replace your strings parameter with new one. But be sure that of what type of web service you are using. Because every web service has different arguments. In this tutorial, it is only one. So you just need to go with web service structure.
gracePosted May 31, 2012, 2:28 AM
yeah i tried installing it in my android phone and it worked. now i wanted to create my own based on your tutorial here. i'm not having errors. its just not working in the emulator. i dont know what seems to be the problem.
Chintan RathodPosted May 31, 2012, 2:19 AM
ya sure.. but what you are doing tell me? Code will not work in emulator of eclipse. You need to try it in real android cell.
gracePosted May 31, 2012, 2:00 AM
i dont know why but I imported your code in eclipse and it is not working. can u help me?? thanks!

Mahesh ChandPosted May 30, 2012, 12:41 PM
Chintan, this is definitely good work. Are you building Android applications for your work or as a hobby?
