FingerprintManager Class

Definition

A class that coordinates access to the fingerprint hardware.

[Android.Runtime.Register("android/hardware/fingerprint/FingerprintManager", ApiSince=23, DoNotGenerateAcw=true)]
public class FingerprintManager : Java.Lang.Object
[<Android.Runtime.Register("android/hardware/fingerprint/FingerprintManager", ApiSince=23, DoNotGenerateAcw=true)>]

Remarks

A class that coordinates access to the fingerprint hardware.

This member is deprecated. See BiometricPrompt which shows a system-provided dialog upon starting authentication. In a world where devices may have different types of biometric authentication, it's much more realistic to have a system-provided authentication dialog since the method may vary by vendor/device.
