Android - way to identify sensor type and to authenticate only with fingerprint method

[erezz33]

trying to find a way to ignore facial recognition of android devices and only allow to authenticate with the fingerprint sensor.
I need to know if there is a method to check in android, which biometric method the user has used to authenticate himself with because if he used only facial recognition I don't want to prompt him a biometric authentication with facial recognition

I am also facing the same problem. I need to differentiate between Face and fingerprint biometric authentication. is there any way to do that ? For business Analytics reporting its very necessary.
