The Fingerprint authentication API

Android Marshmallow now allows us, the developers, to authenticate users with their fingerprint scans when using such authentication scanners on supported devices.

The Fingerprint API was added to Android Marshmallow via a whole new package:

android.hardware.fingerprint

The package contains four classes:

  • FingerprintManager.AuthenticationCallback

  • FingerprintManager.AuthenticationResult

  • FingerprintManager.CryptoObject

Each class has a specific role in our fingerprint authentication process.
