Support 16kb page size for Android libfs-native

Question

I'm facing the following issue with my React Native app using Expo:

"The app must be compatible with page sizes of 16 KB of memory by November 1, 2025."

The libraries listed in Google Play Console are:

base/lib/arm64-v8a/libfs-native.so

base/lib/x86_64/libfs-native.so

All my dependencies are up to date, but I don’t know what this library is.

I’ve already updated all dependencies and Expo using expo-doctor

Can anyone help me identify which library this is, so I can find a way to fix the warning in the Google Play Console?

This library is used by fullstory-react-native. Reach out to their support so they hopefully update their library to support android 16kb pages. — ethanneff

Updating Fullstory package might not be enough. Although you can see in there docs that the support for 16KB was added in July 2025 :

I found out that I had a specific version in my build.gradle of Fullstory. Just Update it to the proper version and you are good to go:

        classpath 'com.fullstory:gradle-plugin-local:1.65.0'
