方法详细资料

from

public static FingerprintManagerCompat from(android.content.Context context)

hasEnrolledFingerprints

public boolean hasEnrolledFingerprints()

Determine if there is at least one fingerprint enrolled.

返回:

true if at least one fingerprint is enrolled, false otherwise

isHardwareDetected

public boolean isHardwareDetected()

Determine if fingerprint hardware is present and functional.

返回:

true if hardware is present and functional, false otherwise.

authenticate

public void authenticate(FingerprintManagerCompat.CryptoObject crypto,
                         int flags,
                         android.os.CancellationSignal cancel,
                         FingerprintManagerCompat.AuthenticationCallback callback,
                         android.os.Handler handler)

Request authentication of a crypto object. This call warms up the fingerprint hardware and starts scanning for a fingerprint. It terminates when FingerprintManagerCompat.AuthenticationCallback.onAuthenticationError(int, CharSequence) or {@link AuthenticationCallback#onAuthenticationSucceeded(AuthenticationResult) is called, at which point the object is no longer valid. The operation can be canceled by using the provided cancel object.

参数:

crypto - object associated with the call or null if none required.

flags - optional flags; should be 0

cancel - an object that can be used to cancel authentication

callback - an object to receive authentication events

handler - an optional handler for events
