🚨 Important Update for Android & Flutter Developers – 16 KB Page Support
Google Play is introducing a major requirement that will affect all new app submissions and updates in the coming months. If you’re an Android or Flutter developer, it’s critical to prepare your projects now to avoid rejections, crashes, or installation failures on future devices.
🔴 What’s Changing?
Starting November 1, 2025, all Android apps targeting Android 15 or higher must support 16 KB memory page sizes on 64-bit devices.
Historically, Android used 4 KB pages for memory management. With modern devices shipping with much larger RAM, Android is moving towards 16 KB and larger page sizes for improved memory performance and efficiency.
From May 1, 2026, Google Play will block all app updates that do not meet this requirement. That means if your app isn’t compatible, you won’t be able to push updates to your users.
⚠️ Who Is Affected?
Pure Dart/Java/Kotlin apps → Safe (these don’t use native libraries).
Apps using NDK or plugins that depend on native .so libraries → Must be rebuilt.
If you ignore this, your app may:
Fail to install on future devices
Crash on startup
Be rejected from the Google Play Store
🛠 How to Prepare
To make your app ready for this change, here are the steps recommended by Google and the Flutter team:
Upgrade your toolchain
Use AGP 8.5.1+
Update to the latest Gradle
Use NDK r28+
Update Flutter SDK and plugins
Most popular plugins are already updated for 16 KB support, but check if your dependencies rely on native libraries.
Rebuild your app
Run the following to generate a fresh app bundle with updated libraries:
flutter clean && flutter build appbundle
Test on Android 15 with 16 KB page size
Use the command below to confirm the device or emulator is running with 16 KB pages:
adb shell getconf PAGE_SIZE

💡 Final Thoughts
This is not optional. If you don’t act now, your app updates will be blocked starting in 2026. Even if your app works fine today, future devices with 16 KB memory pages will fail to run apps built only for 4 KB pages.
I’ve already started preparing my projects by upgrading dependencies and testing on Android 15 emulators. The sooner you test and rebuild, the smoother your transition will be.
👉 Have you checked whether your apps and plugins are ready for 16 KB support?
