opencv+qt+android

edit

hey guys! could anybody give a step-by-step tutorial for setting up qt for building android applications using opencv?

I have a qt and i can to create android projects. Also i have opencv, built for windows and i can to create windows projects using opencv. Now i wanna to create android application using opencv library. I've downloaded opencv-android from here and what should i do next? Is it need to build opencv from sources like it need when building opencv for windows? or i can simply use *.a files from OpenCV-2.4.10-android-sdk\sdk\native\libs?
