I know it sounds like a stupid question, but I've tried to find the latest Ksoap2 jar files on google but to no avail. I think the latest versions are 3+, but so far I have only found deprecated versions of it.
On github:
https://github.com/simpligility/ksoap2-android
There isn't any ksoap2 jar file at all. Any idea how to get the latest version of the file?
The current ksoap2-android jars are located here. For future reference, you can find the repository for the releases in the pom.xml (for example, in the current 3.6.2 version) and on the project website.
