Functions

func Init

func Init(env *jni.Env) error

Init resolves all JNI class and method references for this package. It is safe to call multiple times (uses sync.Once internally). Exported for E2E testing on Android.

Types

type Manager

type Manager struct {
	VM  *jni.VM
	Ctx *app.Context
	Obj *jni.GlobalRef
}

Manager wraps android.hardware.fingerprint.FingerprintManager.

func NewManager

func NewManager(ctx *app.Context) (*Manager, error)

NewManager obtains android.hardware.fingerprint.FingerprintManager from the Android system service manager.

func (*Manager) Close

func (m *Manager) Close()

Close releases the global reference to the underlying Java object. After Close, the Manager must not be used.

func (*Manager) HasEnrolledFingerprints

func (m *Manager) HasEnrolledFingerprints() (bool, error)

HasEnrolledFingerprints calls android.hardware.fingerprint.FingerprintManager.hasEnrolledFingerprints.

func (*Manager) IsHardwareDetected

func (m *Manager) IsHardwareDetected() (bool, error)

IsHardwareDetected calls android.hardware.fingerprint.FingerprintManager.isHardwareDetected.

func (*Manager) ToString

func (m *Manager) ToString() (string, error)

ToString calls android.hardware.fingerprint.FingerprintManager.toString.

type ManagerAuthenticationCallback

type ManagerAuthenticationCallback struct {
	VM  *jni.VM
	Obj *jni.GlobalRef
}

ManagerAuthenticationCallback wraps android.hardware.fingerprint.FingerprintManager$AuthenticationCallback.

func (*ManagerAuthenticationCallback) OnAuthenticationError

func (m *ManagerAuthenticationCallback) OnAuthenticationError(arg0 int32, arg1 string) error

OnAuthenticationError calls android.hardware.fingerprint.FingerprintManager$AuthenticationCallback.onAuthenticationError.

func (*ManagerAuthenticationCallback) OnAuthenticationFailed

func (m *ManagerAuthenticationCallback) OnAuthenticationFailed() error

OnAuthenticationFailed calls android.hardware.fingerprint.FingerprintManager$AuthenticationCallback.onAuthenticationFailed.

func (*ManagerAuthenticationCallback) OnAuthenticationHelp

func (m *ManagerAuthenticationCallback) OnAuthenticationHelp(arg0 int32, arg1 string) error

OnAuthenticationHelp calls android.hardware.fingerprint.FingerprintManager$AuthenticationCallback.onAuthenticationHelp.

func (*ManagerAuthenticationCallback) OnAuthenticationSucceeded

func (m *ManagerAuthenticationCallback) OnAuthenticationSucceeded(arg0 *jni.Object) error

OnAuthenticationSucceeded calls android.hardware.fingerprint.FingerprintManager$AuthenticationCallback.onAuthenticationSucceeded.

func (*ManagerAuthenticationCallback) ToString

func (m *ManagerAuthenticationCallback) ToString() (string, error)

ToString calls android.hardware.fingerprint.FingerprintManager$AuthenticationCallback.toString.

type ManagerAuthenticationResult

type ManagerAuthenticationResult struct {
	VM  *jni.VM
	Obj *jni.GlobalRef
}

ManagerAuthenticationResult wraps android.hardware.fingerprint.FingerprintManager$AuthenticationResult.

func (*ManagerAuthenticationResult) GetCryptoObject

func (m *ManagerAuthenticationResult) GetCryptoObject() (*jni.Object, error)

GetCryptoObject calls android.hardware.fingerprint.FingerprintManager$AuthenticationResult.getCryptoObject.

func (*ManagerAuthenticationResult) ToString

func (m *ManagerAuthenticationResult) ToString() (string, error)

ToString calls android.hardware.fingerprint.FingerprintManager$AuthenticationResult.toString.

type ManagerCryptoObject

type ManagerCryptoObject struct {
	VM  *jni.VM
	Obj *jni.GlobalRef
}

ManagerCryptoObject wraps android.hardware.fingerprint.FingerprintManager$CryptoObject.

func (*ManagerCryptoObject) GetCipher

func (m *ManagerCryptoObject) GetCipher() (*jni.Object, error)

GetCipher calls android.hardware.fingerprint.FingerprintManager$CryptoObject.getCipher.

func (*ManagerCryptoObject) GetMac

func (m *ManagerCryptoObject) GetMac() (*jni.Object, error)

GetMac calls android.hardware.fingerprint.FingerprintManager$CryptoObject.getMac.

func (*ManagerCryptoObject) GetSignature

func (m *ManagerCryptoObject) GetSignature() (*jni.Object, error)

GetSignature calls android.hardware.fingerprint.FingerprintManager$CryptoObject.getSignature.

func (*ManagerCryptoObject) ToString

func (m *ManagerCryptoObject) ToString() (string, error)

ToString calls android.hardware.fingerprint.FingerprintManager$CryptoObject.toString.
