I need to use .Net wcf web service. but I can't success it. I saw error and it is written:

Answer 1

first off, I assume you didn't forget to add suitable permissions in your app's manifest.

now you have a couple of problems, first you are trying network access in the UI thread which is not allowed by Android for API 12 and up, I expect a "network on main thread exception" to appear in your LogCat. You just have to move the ksoap2 call to an AsyncTask or so.

the other problem which I faced before is that I didn't specify a namespace in my wcf web service, so tempuri.org is put by default and it was not working, I had to change it to something else and use it and then it worked like a charm.

try to solve the first problem and run the app, you may not have a problem with tempuri.org but if it still crash then change the namespace in your service, publish it and run your app again.

Answer 2

In the android code don't append ?WSDL. Just write address up to Service.svc or you can copy the address from <soap:address location="..."/> tag of WSDL file. I hope it might work for you.
