lock options

Android 17 introduces a system app locking feature, enhancing mobile security with a new permission structure called LOCK_APPS, allowing only system apps and designated launchers to execute this functionality. This feature utilizes the Biometric Prompt API for user authentication via fingerprint, facial recognition, or PIN. Users can lock or unlock apps by long-pressing the app icon on the launcher, which sends a SETAPPLOCK request to Android's core security service. The app lock will only be available on handheld devices, excluding Android Automotive, Wear OS, and Android TV. The feature is expected to debut later in the rollout of Android 17, benefiting Xiaomi devices and HyperOS.
