Google has announced a significant change in its submission rules for Android apps, particularly for those targeting Android 15 and above. Starting from November 1, 2025, new apps and updates will be required to support 16 KB memory page sizes, replacing the long-standing 4 KB standard. This adjustment is part of Google’s initiative to modernize memory management in Android devices, accommodating the growing RAM capacities found in newer models, like the Pixel 9.
Android’s memory management has traditionally relied on dividing memory into fixed-size pages of 4 KB. However, with increasing RAM in devices, newer configurations are adopting 16 KB pages. This shift aims to reduce overhead, enhance app performance, and provide several advantages, including an 8% faster system boot-up, a 4.5% increase in battery life, a 30% speed boost in app launches, and a 6.6% quicker camera activation.
For developers, this change means that apps not using native code will not require any adjustments. However, those that utilize native libraries or SDKs will need to update their components. Apps developed entirely with native code must be recompiled using updated toolchains.
It is crucial for all apps to be assessed for their compatibility with the new memory page size. Using the Play Console’s App Bundle Explorer, developers can check their apps’ readiness for the transition. They are also encouraged to conduct testing on real devices that are compatible with 16 KB pages to ensure seamless performance.
As the deadline approaches, Google emphasizes the importance of early evaluations. Many popular applications, especially those built on frameworks like Flutter or React Native, are already compatible with this change. While the adjustments may be relatively minor for developers, the potential performance benefits for users could be significant given the ongoing advancements in Android hardware.
