Answer 1

biometrics API provides BiometricConstants for error handling

override fun onAuthenticationError(errorCode: Int, errString: CharSequence) {
    super.onAuthenticationError(errorCode, errString)

    //The device does not have a biometric sensor.
    if (errorCode == BiometricPrompt.ERROR_HW_NOT_PRESENT){
      //Do something
    }
}
