⚠️ Support for Android 16 KB page size

[vkukade-altir]

Hi @baronha ,
First of all, thank you for this awesome library and all your efforts in maintaining it 🙏

Background

Google has announced that by November 1, 2025, all native libraries published to Google Play must support a 16 KB page size.
Reference: Page Size Support Documentation

Currently, when building with latest version of react-native-multiple-image-picker (2.2.3), the following warnings appear:

libMultipleImagePicker.so - 4KB load section alignment, but 16 KB is required.
libimage_processing_util_jni.so - 4KB load section alignment, but 16 KB is required.

Investigation

Based on the discussion here:
• Google Issue Tracker
• CameraX Developers Group

It seems that:
• libimage_processing_util_jni.so is bundled with androidx.camera:camera-core.
• Versions 1.2.x / 1.3.x of CameraX were compiled with 4KB page size alignment, causing the warning.
• This is fixed starting from CameraX 1.4.0.

Dependency Analysis

react-native-multiple-image-picker doesn’t pull CameraX directly but instead depends on:

implementation 'io.github.lucksiege:camerax:v3.11.2'

From dependency resolution:

io.github.lucksiege:camerax:v3.11.2
↳ androidx.camera:camera-view:1.2.1
↳ androidx.camera:camera-core:1.2.1

This confirms that the library currently uses CameraX 1.2.1, which does not support 16KB page size.

Could you please make the changes to make this library 16kb Page size compatible.

io.github.liyuhaolol:camerax:v3.11.5

Seems to offer 16kb support.

To achieve compatibility with 16KB memory pages in this package, you need to do the following:

1. Navigate to the directory ../node_modules/@baronha/react-native-multiple-image-picker/android
2. Open the file CMakeLists.txt for editing and add the following lines to the end of the file:

set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -Wl,-z,max-page-size=16384")
set(CMAKE_C_FLAGS "${CMAKE_C_FLAGS} -Wl,-z,max-page-size=16384")

3. Then navigate to the directory ../node_modules/react-native-nitro-modules/android
4. Open the file CMakeLists.txt for editing and add the following lines to the end of the file:

set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -Wl,-z,max-page-size=16384")
set(CMAKE_C_FLAGS "${CMAKE_C_FLAGS} -Wl,-z,max-page-size=16384")

PS: In both directories, delete the .cxx directory before building for a clean build.

I tested with package version 2.2.4, react-native-nitro-modules version 0.29.8, and RN 0.79.

要使此软件包与 16KB 内存页兼容，您需要执行以下操作：

1. 导航至该目录../node_modules/@baronha/react-native-multiple-image-picker/android
2. 打开文件CMakeLists.txt进行编辑，并在文件末尾添加以下几行：

set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -Wl,-z,max-page-size=16384")
set(CMAKE_C_FLAGS "${CMAKE_C_FLAGS} -Wl,-z,max-page-size=16384")

3. 然后导航到该目录../node_modules/react-native-nitro-modules/android
4. 打开文件CMakeLists.txt进行编辑，并在文件末尾添加以下几行：

set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -Wl,-z,max-page-size=16384")
set(CMAKE_C_FLAGS "${CMAKE_C_FLAGS} -Wl,-z,max-page-size=16384")

PS：在两个目录中，.cxx构建之前请删除目录，以确保构建过程干净。

我使用软件包版本 2.2.4、react-native-nitro-modules 版本 0.29.8 和 RN 0.79 进行了测试。

Deprecated Gradle features were used in this build, making it incompatible with Gradle 9.0.

You can use '--warning-mode all' to show the individual deprecation warnings and determine if they come from your own scripts or plugins.

For more on this, please refer to https://docs.gradle.org/8.13/userguide/command_line_interface.html#sec:command_line_warnings in the Gradle documentation.

I successfully packaged the application once without any problems, but this error occurred later. I've tried clearing the cache, deleting modules, deleting the android directory, and rebuilding, but the same error still occurs. Why?

You only need to add "-DANDROID_SUPPORT_FLEXIBLE_PAGE_SIZES=ON" and force to use camerax that support 16kb to node_modules/@baronha/react-native-multiple-image-picker/android/build.gradle. Here's my yarn 4 patch

Edit: My patch only works if you don't use record video function.
