//set description
fingerprintConfig.setDescription();
//set touch senesor tips
fingerprintConfig.setTouchSensorTips(R.string.biometriclock_fingerprint_touch_sensor);
//set touch senser authenticate failed tips
fingerprintConfig.setTouchSensorFailedTips(R.string.biometriclock_fingerprint_touch_sensor_failed)
