The support library has been superseded by [AndroidX](/jetpack/androidx) which is part of [Jetpack](/jetpack). We recommend using the AndroidX libraries in all new projects. You should also consider [migrating](/jetpack/androidx/migrate) existing projects to AndroidX. To find the AndroidX class that maps to this deprecated class, see the AndroidX support library [class\n| mappings](/jetpack/androidx/migrate/class-mappings).\n\nClasses\n-------\n\n|-------------------------------------------------------------------------------------------------------------------------------------------------------|---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|\n| [FingerprintManagerCompat](/reference/android/support/v4/hardware/fingerprint/FingerprintManagerCompat) | A class that coordinates access to the fingerprint hardware. |\n| [FingerprintManagerCompat.AuthenticationCallback](/reference/android/support/v4/hardware/fingerprint/FingerprintManagerCompat.AuthenticationCallback) | Callback structure provided to [authenticate(CryptoObject, int, CancellationSignal, AuthenticationCallback, Handler)](/reference/android/support/v4/hardware/fingerprint/FingerprintManagerCompat#authenticate(android.support.v4.hardware.fingerprint.FingerprintManagerCompat.CryptoObject, int, android.support.v4.os.CancellationSignal, android.support.v4.hardware.fingerprint.FingerprintManagerCompat.AuthenticationCallback, android.os.Handler)). |\n| [FingerprintManagerCompat.AuthenticationResult](/reference/android/support/v4/hardware/fingerprint/FingerprintManagerCompat.AuthenticationResult) | Container for callback data from [authenticate(CryptoObject, int, CancellationSignal, AuthenticationCallback, Handler)](/reference/android/support/v4/hardware/fingerprint/FingerprintManagerCompat#authenticate(android.support.v4.hardware.fingerprint.FingerprintManagerCompat.CryptoObject, int, android.support.v4.os.CancellationSignal, android.support.v4.hardware.fingerprint.FingerprintManagerCompat.AuthenticationCallback, android.os.Handler)). |\n| [FingerprintManagerCompat.CryptoObject](/reference/android/support/v4/hardware/fingerprint/FingerprintManagerCompat.CryptoObject) | A wrapper class for the crypto objects supported by FingerprintManager. |\n\n-\n\n Classes\n -------\n\n - [FingerprintManagerCompat](/reference/android/support/v4/hardware/fingerprint/FingerprintManagerCompat)\n - [FingerprintManagerCompat.AuthenticationCallback](/reference/android/support/v4/hardware/fingerprint/FingerprintManagerCompat.AuthenticationCallback)\n - [FingerprintManagerCompat.AuthenticationResult](/reference/android/support/v4/hardware/fingerprint/FingerprintManagerCompat.AuthenticationResult)\n - [FingerprintManagerCompat.CryptoObject](/reference/android/support/v4/hardware/fingerprint/FingerprintManagerCompat.CryptoObject)"]]
