The term fingerprint recognition sounds familiar, but it's not used much in the actual development process. Google started with Android6.0 (API23) to provide standard fingerprint recognition support, and to provide external fingerprint identification related interface. In addition to fit 6.0 and above system, the main also provides 6.0 of the following equipment

Recently, the project needs to use the fingerprint identification function, after consulting the relevant information, organized into this article. Fingerprint recognition is a new feature after Android 6.0, so it is necessary to determine whether the system version of the user's phone supports fingerprint recognition

Fingerprint recognition is a new feature after Android 6.0, so it is necessary to determine whether the system version of the user's phone supports fingerprint recognition when it is used. In addition, in the actual development scenario, there are two main scenarios for using fingerprints: Pure local use. That is, after the user completes the
