Google's AndroidX Security State Enables Component-Level Patch Verification

Google introduced the AndroidX Security State and Security State Provider libraries, letting apps verify Android security at the component level instead of relying on a single device-wide patch date. The library distinguishes three patch levels — Device SPL, Published SPL, and Available SPL — for the kernel, system, and Google Play modules.

• Three patch levels: Device SPL, Published SPL, and Available SPL
• Verification covers kernel, system, and Google Play modules
• areCvesPatched() and isDeviceFullyUpdated() check specific CVEs
• Security State Provider standardizes update notifications for OEMs
