            The Amazon Fire Game Controller follows the NVidia standard of sending
            AXIS_HAT_X/AXIS_HAT_Y results when the user hits the D-Pad. Only if we
            return false from dispatchGenericMotionEvent() will it then send
            DPAD keycodes.
                    
            But the most popular Android joystick on the market at this time, the
            Nyko Playpad Pro, returns AXIS_HAT_X/AXIS_HAT_Y results when the left
            analog stick hits its extremes, meaning that the analog stick will
            generate DPAD keys if we return false. The Nyko generates DPAD keys
            directly for the DPAD controller.
                    
            So we have two incompatible standards fighting with each other. Probably
            the safest thing to do would be to ask the user to press on their DPAD
            and see what messages we get, but that is beyond the scope of this
            example code.
