⭐ [Android] Support 16kb page size for Android 15+ devices

Description

Description

I am encountering issues when running my app on Android 15 devices with a 16 KB page size, particularly with some native components. Are there any plans to recompile the library to address these issues and ensure compatibility with phones that have a 16 KB page size?

As stated on Android doc,

Beginning with Android 15, Android supports devices that are configured to use a page size of 16 KB (16 KB devices). If your app uses any NDK libraries, either directly or indirectly through an SDK, then you will need to rebuild your app for it to work on these 16 KB devices.

An analysis of my app using the APK Analyzer as described by Android shows that it does use libreanimated.so as native code.

This is the native binary reported by the APK analysis:

libcrashlytics-common.so

Describe the solution you'd like

I would like for libreanimated.so to support 16kb page size phones so that apps supporting sdk 35 do not crash

Hey! 👋

The issue doesn't seem to contain a minimal reproduction.

Could you provide a snack or a link to a GitHub repository under your username that reproduces the problem?

Hey! 👋

It looks like you've omitted a few important sections from the issue template.

Please complete Reanimated version and Description sections.

Hey @k-saparia, is this issue related to react-native-screens, or does it affect this library? From your description I conclude that it is react-native-reanimated who is affected rather than react-native-screens and you should consider opening the issue on it's repo (or let me know, I might be able to transfer the issue there)

Hi there, as of yesterday, it looks like this issue will have to be fixed by November 1st 2025
See announcement from Google: https://android-developers.googleblog.com/2025/05/prepare-play-apps-for-devices-with-16kb-page-size.html

Starting November 1st, 2025, all new apps and updates to existing apps submitted to Google Play and targeting Android 15+ devices must support 16 KB page sizes.

You can see libreanimated.so being flagged using the tools at
https://developer.android.com/guide/practices/page-sizes#16-kb-impact

Hi all, support for 16 KB page size for Android 15+ devices was added in #7037 by @m-bert which has been released in 3.17.0 and 4.0.0-beta.3. Please upgrade react-native-reanimated to 3.17.0 or newer (current latest is 3.17.5).

If you need to use an older release of react-native-reanimated without this change, please use patch-package on your own.
