Thanks for your reply.
By the way, I actually found what is my problem, from analyze other working on screen button.
It turns out the compiled framework don't add META-INF.
After I add that folder to my compiled framework, *with total commander, It works.
And editing the SystemUI turns out unnecessary.
What I still wonder is how to add menu button (the right key, beside back and home button), and also make holding home button show the ics style recent app (the one that you can swipe to remove it from recent app).
