memory page size

Android is transitioning to a 16 KB page size, which will become mandatory for applications in the Google Play Store by November 1, 2025. This change replaces the previous 4 KB page size and aims to enhance performance by improving memory management and reducing overhead. The introduction of Android 15 has been refactored to support this larger page size, with testing currently available on Pixel 8 and Pixel 9 devices. Expected performance improvements include faster app launches (3% to 30% faster), improved battery usage (average gain of 4.5%), quicker camera starts (4.5% to 6.6% faster), and speedier system boot-ups (approximately 8% faster). Apps without native code should remain compatible, while those using libraries or SDKs with native code may need updates. Apps containing native code might require recompilation and review for compatibility. Developers can check memory page size support through the Play Console.

Android developers are preparing for a transition to a 16 KB memory page size, expected to improve performance by 5–10% across applications and games. Google has introduced developer options for testing on Pixel 8 and Pixel 9 devices, with support from other OEMs like Samsung and Xiaomi anticipated. Developers using native code must assess and rebuild their apps, ensuring compatibility with the new page size by upgrading to Android Gradle Plugin version 8.5.1 or later and using NDK version r28 or later. Applications without native code will remain compatible without modification. Testing for compatibility can be done using emulators or physical devices like the Pixel 8/8 Pro and future Pixel 9 models. Developers are advised to avoid hardcoding assumptions about memory page sizes to prevent compatibility issues.
