✨ Support 16kb page size for Android 15+ devices

[k-saparia]

What feature or enhancement are you suggesting?

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 libVisionCamera as native code.

This is the native binary reported by the APK analysis:

libVisionCamera.so

Describe the solution you'd like

• I would like for libVisionCamera 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: Need support for 16KB page size on Android facebook/react-native#45054

What Platforms whould this feature/enhancement affect?

Android

Alternatives/Workarounds

No workaround I have investigated so far.

should be just a simple flag to CMake, but I think this will break backwards compat

[k-saparia]

If possible, It should be backward compatible with old and new architecture 🤔 Otherwise, worth to have a force update.

I'm talking about older android SDK/NDK versions

[mrousavy]

This already works in latest VisionCamera afaik

Is there an update on this, Google is mandating apps to support 16kb page size by November, this is a blocker for us at the moment

[jesuscc1993]

If I haven't misunderstood:

Google will enforce targetSdkVersion 35 by Aug 31st 2025.
This is an assumption given they enforced 33 on Aug 31st 2023 and 34 on Aug 31st 2024:
https://support.google.com/googleplay/android-developer/answer/11926878

And they require you to support 16 KB page sizes if you target SDK 2025 so, by extension, every Android app will need to support this by Nov 1st 2025. We can omit the targetSdkVersion 35 part of the requirement as it'll have already been enforced.
https://developer.android.com/guide/practices/page-sizes

Looking at the steps to support this page size, it does not look like this dependency has been updated to do so:
https://developer.android.com/guide/practices/page-sizes
(Unless it's using NDK >= 28, which I was not able to verify).

Regardless, we're still getting the 16KB page size popup using the latest version of this library.

I don't understand why this issue was closed. When I add react-native-vision-camera to my React Native app that targets Android 15, I get the same results as @k-saparia, and I see a popup on my app that says: "This app isn't 16 KB compatible. ELF alignment check failed."

I was able to fix this issue by removing react-native-vision-camera and adding this library instead: https://github.com/teslamotors/react-native-camera-kit/

I also had to apply the patch in this PR: teslamotors/react-native-camera-kit#699

[k-saparia]

They have created fix for vision camera 16 KB support #3543

[k-saparia]

However, I fixed by adding support in their cmake file. Here's my patch work!
