How to get Fingerprint input from user and save to sqlite in android [closed]

Answer 1

1. In technical terms, Android OS stores Fingerprints in TEE (stands for Trusted Execution Environment), TEE is separate and isolated area in phone's hardware or software depending on the way device is manufactured. TEE will never let us in even if device is rooted. Check this for more details about Trusty OS

2. If your requirement is to get fingerprint signature (which is a critical practice from user's privacy point of view) you'll have to buy a 3rd party fingerprint scanner and integrate with your app.
