		## Biometric HALs ##
		---

		## Overview: ##

		The interfaces within the biometrics.* HAL tree are used by the Android Biometric Services
		(e.g. FingerprintService, FaceService) to discover and operate biometric sensors on the device.

		More details and versioning information can be found within each particular HAL.

		More complete information about the Android Biometric HALs and subsystem can be found at
		[source.android.com](https://source.android.com/security/biometric).

		// This file is a snapshot of an AIDL interface (or parcelable). Do not try to
		// edit this file. It looks like you are doing that because you have modified
		// an AIDL interface in a backward-incompatible way, e.g., deleting a function
		// from an interface or a field from a parcelable and it broke the build. That
		// breakage is intended.
		//
		// You must not make a backward incompatible changes to the AIDL files built
		// with the aidl_interface module type with versions property set. The module
		// type is used to build AIDL files in a way that they can be used across
		// independently updatable components of the system. If a device is shipped
		// with such a backward incompatible change, it has a high risk of breaking
		// later when a module using the interface is updated, e.g., Mainline modules.
