Well, good job, it's cool that you have opencv running on your phone, and
the gui works as well..
The images you decoded on the x86 are the same taken from the N810 camera?
It doesn't seem to be a compile problem.
I suggest you use qrcode-0.9, if you can write your entire application in
Java you have solved all your problems. You will notice that libdecodeqr
is in practice useless because it decodes only some images.
