Parsing List of Soap Objects from Web Service in Android

    In previous post, I presented a simple way to consuming SOAP web service. The fact that, data responsed from server usually complicated. For example, a list of json objects, json array or list of Soap Objects,...
    In this tutorial post, you will learning how to parsing a list of soap objects were responsed form a web service by using k-soap2 library and showing them to view after all.

1. Download and import library

- Launch Android Studio and start a new project.
- Download lastest k-soap2 jar file from Project's download page.
- Put yout jar file to your project - see this article for how to import external  jar it into Android Studio project.

2. Web service preview

Okey, we have a dotNet web service like this:
As you can see, client must transfer 3 properties for each request (appType (int), userName (String) and sessionId(String)). Invoke a test after enter inputs, we have this result:
Now, we start making an Android project which consuming it.

3. Coding project core 

    After importing successfull library, we start coding for our project. In this example, we will make a request to server and retrieve a list of Banks from it.
For call a soap method using ksoap we need these 4 things (URL ADRESS, SOAP ACTION ADRRESS, NAMESPACE, METHOD NAME. Soap Action = Namespace + Method name). Define these properties value in ConstantString.java:

Make a model BankInfo with some information:
    For making request to server, we'll use an AsyncTask and run in background thread. In it:
- Checking Internet connection (in onPreExcute method)
- Creating and set properties value for our SoapObject, create HttpRequest, Envelop, sending request and receiving response data in doInbackground method.
- processing data and call back to UI thread (MainActivity) in onPostExcute method.
    getServiceResult method (creating, sending request and receive data):
Full GetBankTask.java source code:
    In our activity, the most important method is calling back data from AsyncTask, parsing list of Soap Objects here, get each soap object property by getPrimitivePropertyAsString method:
Full MainActivity.java code:

4. Creating some necessary files

- Layout for activity:

- Layout for each bank entity: showing name and it's code:
- local build.gradle file:
- Strings resource:
- open AndroidManifest.xml add adding permissions to checking network state and using Internet:

5. Running application
