Hi,
AppUpdating latest release uses okHttp/okHttpUtils. Anyway you have the full source code to the lib (post #1) so any change needed to properly work on https could be applied. Sorry if I can't volunteer myself but I'm very busy these days.
Quite sorry, i actually checked your code, and there is a significant difference between v1.26 and v1.30...
You are actually using the right Http Library for HTTPS on the last version!!!
I was using 1.26.......
Problem solved, Thank You!
