last year, Google launched the new version of the support library AndroidX, and as its description indicates, is a component that provides compatibility with all previous versions of Android. In addition, it is updated separately to the S. O. so that mitigates a little more fragmentation.
Google Now reports that the computer Android Framework and Security has been added to the behavior biometric of Android 10 in all the devices running Android 6.0 or higher.
Library Biometric AndroidX
The new API to biometric library support AndroidX supports multiple form factors of biometric authentication (fingerprint, face, iris…) and makes it much easier for developers to test what biometric sensors have a device in particular. In case you do not have any biometric sensor, the API allows developers to specify they want to use the credentials in your applications.
The API biometrics not only offers several advantages to developers, OEM manufacturers of devices also benefit from the new features because it offers a API user-friendly and standardized which allows you to integrate the support for all types of biometric sensors in its devices.
In Android 6.0 was added official support to the finger sensor, but without providing an interface for authentication. Each manufacturer and application had to design his window to check. In Android 9 was introduced a standardized interface for fingerprints and opened up the API to more times of biometric sensors. With Android 10 introduced the single window for authentication bearing the facial recognition. Now this interface biometric authentication is also available in the previous versions of Android.
