To be honest I am not sure if there are still many users of ksoap2-android out there. I have sorta left the Android development efforts myself. A few comments showed up in issues pointing to a missing module and I had a quick look to fix it.
And voila – here is a new 3.6.3 release for you to enjoy and use. And of course I am happy to cut more releases, provided someone else sends me any pull requests with bug fixes or improvements.
I guess at this stage we could update to Java 8 and a whole bunch of stuff, but really it might not be worth it. Just let me know how things are working on the mailing list or the github issue tracker.
