[🐛] [Android] 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 libcrashlytics-common.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 libcrashlytics-common 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: react/react-native#45054

What Platforms whould this feature/enhancement affect?

Android

Alternatives/Workarounds

No workaround I have investigated so far.

Based on the issue you created here: firebase/firebase-android-sdk#6142

android sdk support is in firebase-android-sdk => 33.1.1.

which has already been released in the latest version: https://github.com/invertase/react-native-firebase/blob/main/CHANGELOG.md#bug-fixes-2

For anyone else reading this, note that react-native itself does not support 16kb sizes yet and will not until at least react-native 0.77, but it is a known issue. You will want to hit the subscribe button on the upstream issue for updates react/react-native#45054

There is no work to be done in this repo as far as we are aware, just upstream work in react-native

Hey 👋🏼 Chiming back in on this one, React Native Version 0.77 with 16KB memory page size support has been released a while ago.

Referring to these instructions, I've just checked and i don't see any usages of PAGE_SIZE, getpagesize() or sysconf() on the first look. So therefore, i think the only needed change should be adding the following to the android/build.gradle file:

android {
  defaultConfig {
    externalNativeBuild {
      cmake {
        arguments "-DANDROID_SUPPORT_FLEXIBLE_PAGE_SIZES=ON"
      }
    }
  }
}

@mikehardy let me know if you think there are further changes to be made. I'd be glad to help adding support for this one! 🙌🏼
