- Android 15 introduces page-size-agnostic support, allowing devices to run with either 4 KB or 16 KB memory page sizes.
- Starting November 1, 2025, new apps and updates with native C/C++ code must support 16 KB page sizes for Google Play submission.
- Performance benefits include 5-10% overall boost, faster app launches (up to 30%), reduced power draw (4.56%), quicker camera starts (4.48-6.60%), and faster system boot-ups (~0.8 seconds).
- Apps using native code need recompilation for 16 KB compatibility, but the same binary will work on both 4 KB and 16 KB devices.
- Android Studio tools like APK Analyzer, alignment checks, and Lint help identify and update non-compliant libraries.
- Developers should eliminate hardcoded 4 KB assumptions and use runtime queries like getpagesize().
- Android Emulator and on-device testing options (e.g., Pixel 8) support 16 KB page size testing.
