Thank you!
a marginal question: In blog https://android-developers.googleblog.com/2018/06/better-biometrics-in-android-p.html. Bimometrics have support for android O or lower if import library. Where I can get BimometricPrompt compat library and they said Biometricprompt can suppor for face and iris but when I read in document https://developer.android.com/reference/android/hardware/biometrics/BiometricPrompt. I can't see support for iris or face. Biometricprompt is really support for iris and face?

from biometricpromptdemo.

It mean if api <28 I can't use BiometricPrompt?
