I am creating an Android APP and have to connect with the web service of my company to make the login system, I am using the lib KSOAP2 3.3.0.

The path of my WS is for example as: http://www.dominio.com/servicos/sambanet.asmx

My problem that happens:

09-04 10:57:52.835: W/System.err(19717): 
SoapFault - faultcode: 'soap:Client' faultstring: 
'Server did not recognize the value of HTTP Header SOAPAction:
http://www.dominio.com/servicos/ObterIdentificadorLoja.'
faultactor: 'null' detail: org.kxml2.kdom.Node@428e60d0

The variables stored for the connection:

private final String NAMESPACE = "http://tempuri.org/";
private final String URL = "http://www.dominio.com/servicos/ws.asmx";
private final String SOAP_ACTION = "http://tempuri.org/ObterIdentificadorLoja";
private final String METHOD_NAME = "ObterIdentificadorLoja";
private String TAG = "LOGAR";

my WSDL is:

<wsdl:operation name="ObterIdentificadorLoja">
<soap:operation soapAction="http://tempuri.org/ObterIdentificadorLoja" style="document"/>

I need to access the "Get identifier store", only it always gives the error of either the "HEADER could not be recognized" or "Timeout" or "Reference was not set to an instance or an object", and I tried several ways already..

Where I might be missing?

Note: I am emulating on my own phones (Moto X 4.4.4, Samsung Neo 4.1.3, Optimus One 2.3.3)

java android web-service android-eclipse

  • Test, first, all the resources of the webservice here http://www.soapclient.com/soaptest.html

  • everything works normally, @Igorronner! It’s a web service that my company has used for a long time! And we have over 1000 clients connected to it using the same things I’m trying to..

  • where you fill the identifier variable, I did not find.

  • is at the end of the code: identifier = sponse.toString(); It assigns to the identifier the answer of the webservice @Igorronner

  • you are setting the transponder valow in the Property without having yet?

  • not @Igorronner! In Try he is consuming the webservice, and the answer he delivers, he assigns to the identifier! For example, his answer is 2 (int), he assigns to the handle = "2", so it is shown on the screen as a test that has been completed.. In case with this error, only null appears because it cannot connect..

    but that’s beside the point, the problem is he can’t connect...

  • Can someone help me?

After several attempts, I ended up solving the problem myself..

Follow the before and after source:
