Android Controller: Differentiating between LT & RT axes

Android Controller: Differentiating between LT & RT axes

I am trying to implement a mapping method for a Bluetooth Android
controller (snakebyte idroid). When the controller is set in a mode where
the triggers are digital it works fine and the onkey() methods are called.
However, when the triggers are set as analogue I attempt to trap the event
in onGenericMotionEvent(MotionEvent event), but both LT and RT use the
MotionEvent.Z_AXIS id, where LT goes from 0 to -1 and RT from 0 to 1.
Therefore, holding both down cancels them out. Is this just a hardware
flaw or is there a way at the os level to get the different values for
each? When I make a call to getPointerCount() there is only 1 so there
does not seem to be any bundled events like you would expect for the touch
input calls.
Thank you in advance for anyone that might have some insight.
