well, i guess this app works for some phones but some doesnt. 

This is a permission issue which I am trying to figure it out too.

If you look into it, you will find it caused by the l2cap socket.
(At least it happens here to me.)

Only bluez bt stack is supported. So it will work on AOSP but any other ROM 
using proprietary bt stack won't work even if phone is rooted.

CM uses bluez as bt stack so it just works ;)

well, Android alse uses bluez as its bt stack. This problem might be caused by 
your su permission.

It depends on bt stack used by Your phone manufacturer. Some of them use bluez 
and androhid should work on those phones. And some of them use proprietaries bt 
stack - and those phones won't work with androihid.
