How to check Biometrics finger with data on smart card in Tactivo mini reader in android

I am currently developing an Android application that validates biometric data from a fingerprint reader with enrolled biometric data from a smart card. PreciseMobileTKAndroid

lib allows you to validate biometric fingers with local database and owner database in sdk examples. But I cannot use these approaches because these methods depend on the database for registered fingerprints. I also found an interface PBBiometryVerifier

that contains a method verifyTemplateSmartcard()

to validate data from a smart card, if anyone has any development experience with this lib please help me with an example. I don't know how to implement this interface for a custom validation process. Many thanks.
