Disclaimer: I AM a newbie at Android programming :( I have seen a similar question posted here, but the solution did not work for me. I AM trying to meet all the criteria for a properly posted question so please bear with me. I wrote a C# client to test my wcf service (SimpleHTTPTransport) and it works fine over WiFi from a second computer so I know there are no firewall issues. My Android browser can hit http://10.0.0.134:4444/DietService.svc?msdl with no problem. THe service is set for anonymous user, so no login info necessary. I've checked out every possible reference I could find here and elsewhere on the web for 2 days with no help. I'm using ksoap2 2.5.2 and can't get anything to work. I've even tried setting up an Async Task. I've copied allegedly "working" code and still can't get any comm to the wcf service. At this point, I'm totally stumped. Here is my stack trace, code and the variables at the time of transmission:

Stack Trace:

What a learning experience! In searching for more answers, I found that there was a newer ksoap2 library (2.6.0) so I decided to upgrade from 2.5.2.. When I did, I noticed that I was using the 2.5.2 WITHOUT dependencies. After upgrading, my stack trace was much more detailed and indicated a permissions fault. A quick search on the 'net had me check for

 <uses-permission android:name="android.permission.INTERNET"/>

DUH! I forgot to add it to my AndroidManifest.xml file. Bingo! Connection established. Now all I had to deal with was a contract mismatch. That required adding IDietService to the SOAP_ACTION path:

changed:

final static String SOAP_ACTION = "http://tempuri.org/GetFoodName";

to:

final static String SOAP_ACTION = "http://tempuri.org/IDietService/GetFoodName";

Using the WITH-DEPENDENCIES version of the ksoap2 library was the key to the solution. I don't know if the version upgrade helped. I admit that I was confused when my catch block found a null for the e.getMessage() when using the ksoap2 2.5.2 but I assumed (yea, I know) that that was just the way it was. Bottom line -

CHECK YOUR DETAILS!
