Biometric(fingerprint) development from scratch

Hi I am new user here. I am working on Android app in which I am planning to add Android Bio-metric for fingerprint initially and later on face unlock. I am not sure where to start as I don’t see any guide on google developer website. I also don’t see bio-metric chapter in busy coder book. Can any one guide me on it? ( I am unable to find Android development category, due to it this question goes into CWAC. )

I am unable to find Android development category

You never requested access to that category. I found your subscriber record, granted you access to this category, and moved this question to that category.

I also don’t see bio-metric chapter in busy coder book.

See the chapter on device authentication and the chapter on the keystore. I also have some material on it in Elements of Android Q related to the changes in Android 10.
