We calculate the Andreev spectroscopy between a ferromagnetic lead and a Bi/Ni bilayer system. The bilayer system is described by the Anderson-Brinkman-Morel (ABM) state and mixing ABM and $S$-wave states. In both the ABM state and ABM state is mixed with small $S$-wave state, the Andreev conductance is consistent with that obtained in the point-contact experiment [Zhao et al., arXiv:1810.10403]. Moreover, the conductance peak near zero energy is induced by the surface state of the ABM state. Our work may provide helpful clarification for understanding recent experiments.
