SOAP in Android

Like many other Android developers I came to the same problem – parsing SOAP in Android.
My short instruction how to do this…

download ksoap2 sourse files – ksoap2-src-2.1.1.zip (http://sourceforge.net/project/showfiles.php?group_id=158028&package_id=176860)
download kxml2 source files – kxml2-src-2.3.0.zip (http://sourceforge.net/project/showfiles.php?group_id=9157&package_id=58653)
put in your source folder:

ksoap2-src-2.1.1.zip
/src/org/ksoap2/
/src_j2se/org/ksoap2/

kxml2-src-2.3.0.zip
/src/org/kxml2/

take missed kObjects files from here: http://kobjects.cvs.sourceforge.net/viewvc/kobjects/kobjects/src/org/kobjects/
/org/kobjects/base64/Base64.java
/org/kobjects/isodate/IsoDate.java

Use simple code to connect the server

private static final String SOAP_ACTION = "myMethod";
private static final String METHOD_NAME = "myMethod";
private static final String NAMESPACE = "http://mynamespace.com/";
private static final String URL = "http://myserver.com/bean";
 
void test() {
    try {
        SoapObject request = new SoapObject(NAMESPACE, METHOD_NAME);
        request.addProperty("prop1", "myprop");
 
        SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11);
        envelope.setOutputSoapObject(request);
        HttpTransportSE androidHttpTransport = new HttpTransportSE(URL);
        androidHttpTransport.call(SOAP_ACTION, envelope);
 
        Object result = envelope.getResponse();
 
        //handle result here
 
        myExampleHandler.getResults();
    } catch (Exception e) {
        e.printStackTrace();
    }
}

I am trying to do exactly the same things, so I would like to thank you for posting this.

By the way, could you also give an example of ParserHandler (the ContentHandler implementation) ? I am going to search Google, but I think it might be usefull for the next visitors .
villain_dm

ParserHandler extends DefaultHandler-) I think this is a part of regular SAX parser tutorials like this: http://www.anddev.org/parsing_xml_from_the_net_-_using_the_saxparser-t353.html
http://www.piwai.info Piwaï

Thanks for answering so fast. I will have a look at that. Anyway, even without parsing the response, everything works fine (using result.toString() ). So thanks a lot for that !

One more thing for visitors : if you use local webservices while developping, don’t put localhost or 127.0.0.1 in the url, since it will be the localhost of the Emulator, not the one of your computer. You should put your network IP instead (like 192.168.10.10).
villain_dm

well… actually I didn’t do any research in parsing response-) I replaced soap to the simple XML.
result.toString() will be something like anyType{name=value; …}… SAX parser won’t help in this case:)

please see ksoap2 tutorial how to handle this: http://google.com/codesearch/p?hl=en#fNok_iy2ojk/samples/org/ksoap2/samples/amazon/search/AmazonSearchClient.java

Just wanted to give some more feedback :

Android does not currently works fine with HTTPS and some Certificate Authorities, probably due to a lack of implementation of some algorithms. If you happen to encounter the following IOException : “Hostname was not verified”, here is the crappy patch I found : in org.ksoap2.transport.ServiceConnectionSE, I added the following code on line 50 (after “connection.setUseCaches(false);” in the constructor) :

if (connection instanceof HttpsURLConnection) {
((HttpsURLConnection) connection)
.setHostnameVerifier(new AllowAllHostnameVerifier());
}

THIS IS A TEMPORARY AND BAD SOLUTION, since CA are not any more verified.

I tried to use your code, and I did not change anything except namespace, url etc. but it didn’t work.

I tried to debug and every this call : androidHttpTransport.call(SOAP_ACTION, envelope);

I get an unknown error, and fall catch block.

I try to connect a dotnet web service, please help me if you know something..

Below is my func. names etc..

private static final String SOAP_ACTION = “http://tempuri.org/AddIntegers”;
private static final String METHOD_NAME = “AddIntegers”;
private static final String NAMESPACE = “http://tempuri.org/”;
private static final String URL = “http://127.0.0.1:1416/WebServiceTest/Service.asmx”;
Michael

thank you, i tried to get ksoap working the whole last week….and with your tutorial it worked in a few minutes…
good job!
Adam Gaines

For some reason no matter what I do I get the following error:

detailMessage “expected: END_TAG {http://schemas.xmlsoap.org/soap/envelope/}Body (position:END_TAG @1:375 in java.io.InputStreamReader@4377f160) ” (id=830060642608)

Hi,
I’m having a problem accessing my web-service.
This is my code:

private static final String SOAP_ACTION = “”;
private static final String METHOD_NAME = “getPOIS”;
private static final String NAMESPACE = “http://ws.intelliPOI/”;
private static final String URL = “http://10.0.2.2:8084/intelliPOI/GetPOIS”;

//–//

object = new SoapObject(NAMESPACE, METHOD_NAME);
envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11);

object.addProperty(“username”, “ze”);

object.addProperty(“latitude”, 40.211491);
object.addProperty(“longitude”, -8.429201);
envelope.setOutputSoapObject(object);

HttpTransportSE aht = new HttpTransportSE(URL);
try{

aht.call(SOAP_ACTION, envelope);

SoapPrimitive primitive = (SoapPrimitive) envelope.getResponse();
tv.setText(“From Server: ” + primitive);

}catch(Exception e){
e.printStackTrace();
}

//–//

However, I can’t get the webservice to respond.
Can anyone help me?

Hello,
I want to use Android to connect to a WCF.
Please cn you help me to resolve this problem?
I have not any idea to start the work.
Thank you very much
Fran

Luis,

try changing this line:
SoapPrimitive primitive = (SoapPrimitive) envelope.getResponse();
with:
SoapObject soa = (SoapObject ) envelope.getResponse();

Did anyone find a better solution for the https problem?
Manfred Moser

Oh and a KSOAP related note. I have a patched branch that supports attribute parsing. See http://github.com/mosabua/ksoap2-android This fixes issue 17 .. http://code.google.com/p/ksoap2-android/issues/detail?id=17
diengsallah

Hello,
I am using Android to connect to a JAX-WS Web service using KSOAP2.
My Webservice containair is Glassfish v3.
Any time, I get this error from the server:
org.xml.v1. XmlPullParser…
When I use a dump, I see that the server response is that :
Http 404
The requested response () is not available .
Please have you got any idea ?
It is very difficult for me!
Thanks
tobias

Hello,

I used your example and also tried with ksoap2 for android library.

With your example (with the sourcecode) I get an Error with HttptransportSE

With the android ksoap library it works. They use androidhttptransport

But I want to use the source code like you. What can I do?
tobias

Hello,

the code works now with the sourcecode of you from ksoap2.

But there is another problem. I can see the http request and response in wireshark.
And I get an ERROR back in the celsius string.

I think I now why:
10</v:Bo

Its because of that :n0 Namespace tag. With the special android library there is no :n0 in the tag..

Can you give me plz a hint"
tobias

sorry I`m again. It should look like this:
5
0260 35 3c 2f 43 65 6c 73 69 75 73 3e 3c 2f 43 65 6c 5. .

ups…so here:

Hi,
I was following these indication, but when I ran the project I received this error “the application has stopped unexpectedly. please try again”. This error is showed specifically when I execute this line SoapObject request = new SoapObject(NAMESPACE, METHOD_NAME) running the project step by step; any ideas?
Thanks a lot
Twitty

Hi guys I can’t import SoapObject, SoapSerializationEnvelope and HttpTransportSE!!! What more i need!
Piotr

I’v got same error code as Emanuel ( “the application has stopped unexpectedly. please try again”) when I’m creating new instance of SoapObject. I’m using ksoap2 ver 2.4 form google site.
Any ideas how to get around this problem ?
Axel

THIS IS IMPORTANT!

You must put this line on your project’s AndroidManifest file

And this is an example of my vars:

private static final String SOAP_ACTION = “http://tempuri.org/GetRides”;
private static final String METHOD_NAME = “GetRides”;
private static final String NAMESPACE = “http://tempuri.org/”;
private static final String URL = “http://iphonedemo.stage.com/SOAP/iPhoneWS.asmx”;

It works that way. (The urls are just an example you have to put your owns).
Axel

Sory the line is:

uses-permission android:name=”android.permission.INTERNET”
Nikhil

Can there be a sample service for above client I am find diffculty in creating a webservice.
Gábor Auth

Hi,

I’ve created a new SOAP client for the Android platform, it is use a JAX-WS generated interfaces, but it is only a proof-of-concept yet.

If you are interested, please try the example and/or watch the source: http://wiki.javaforum.hu/display/ANDROIDSOAP/Home
kishore

hi guys, this is a great tutorial it works fine but, I am having problem on send xml string as request like, for authentication of user

String myxml=”"+”string”+”"+
“”+”string”+”"+
“”+”318974764453″+”";.

request.addProperty(“tagname”, myxml);

is this the right way.
kishore

tags are missing name,password,tokenid.

axel thanks for the comment that is very important
kishore

hi can u suggest the best way to call web service that need to send request in xml format exactly as the below soap, is it possible in ksoap2

the soap message is

?xml version=”1.0″ encoding=”utf-8″?>
soap:Envelope xmlns:xsi=”http://www.w3.org/2001/XMLSchema-instance” xmlns:xsd=”http://www.w3.org/2001/XMLSchema” xmlns:soap=”http://schemas.xmlsoap.org/soap/envelope/”>
soap:Body>
employee xmlns=”http://abcd.com/”>
emp>
Name>string/Name>
Designation>string/Designation>
/emp>
/employee>
/soap:Body>
/soap:Envelope>

responce will be

?xml version=”1.0″ encoding=”utf-8″?>
soap:Envelope xmlns:xsi=”http://www.w3.org/2001/XMLSchema-instance” xmlns:xsd=”http://www.w3.org/2001/XMLSchema” xmlns:soap=”http://schemas.xmlsoap.org/soap/envelope/”>
soap:Body>
employeeResponse xmlns=”http://abcd.com/”>
employeeResult>string/employeeResult>
/employeeResponse>
/soap:Body>
/soap:Envelope>
sh

where to run the following code?
