errorCode	int: An integer ID associated with the error.
errString	CharSequence: A human-readable string that describes the error.

onAuthenticationFailed

public void onAuthenticationFailed (FragmentActivity activity)

Called when a biometric (e.g. fingerprint, face, etc.) is presented but not recognized as belonging to the user.

Parameters
activity	FragmentActivity: FragmentActivity the prompt is attached to

onAuthenticationSucceeded

public void onAuthenticationSucceeded (FragmentActivity activity, 
                BiometricPrompt.AuthenticationResult result)

Called when a biometric (e.g. fingerprint, face, etc.) is recognized, indicating that the user has successfully authenticated.

After this method is called, no further events will be sent for the current authentication session.

Parameters
activity	FragmentActivity: FragmentActivity the prompt is attached to
result	BiometricPrompt.AuthenticationResult: An object containing authentication-related data.
