    fingerprint: send cancel-message to system · b0b78348
    Lukas0610 authored
    Android expects a FINGERPRINT_ERROR_CANCELED error-message if a
    fingerprint authentication-requested was cancelled.
    
    As bauth doesn't deliver such a message on its own, we use the
    already notify-wrapper to send a message to Android if the
    authentication was cancelled by bauth to allow a proper operation
    of the fingerprint-service.
    
    Some devices (hero, hero2) with the fingerprint scanner embedded in
    the home button need this for the "config_fingerprintWakeAndUnlock"
    option to work reliably.
