✨ Support 16kb page size for Android 15+ devices

[k-saparia]

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:

libreanimated.so

Describe the solution you'd like

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

Additional context

Android doc: https://developer.android.com/guide/practices/page-sizes#compile-16-kb-alignment
react-native thread: facebook/react-native#45054

What Platforms whould this feature/enhancement affect?

Android

Alternatives/Workarounds

No workaround I have investigated so far.

If you upgrade to Android 36 (targetSdkVersion 36) and encounter errors like:

then add the following configuration in your android/app/build.gradle file to exclude the problematic libraries:

android {
    ndkVersion rootProject.ext.ndkVersion
    buildToolsVersion rootProject.ext.buildToolsVersion
    compileSdk rootProject.ext.compileSdkVersion

    packagingOptions {
        // Add these lines to handle 16KB page size issue
        jniLibs {
            useLegacyPackaging = true
        }

        // Exclude problematic libraries if needed
        exclude "lib/x86_64/libandroidlame.so"
        exclude "lib/x86_64/libucrop.so"
    }
}
