I still got problems, i don't have idea why it is not working, when i tried last time to compile this - it worked, now i'm trying to compile (i haven't changed anything) - it's not working.
It's working well on desktop version Qt 5.4.0, i can't get it working on android http://scr.hu/0tgp/6ntgy
undefined reference, but the same QCA files are with desktop and android version so i don't know what is wrong :/
