Google Play's 16 KB page size requirements

[simonecorsato]

Google Play's 16 KB page size requirements must be fulfilled starting from 1st November.
I currently get the following warning:

APK app-SwingMobile-debug.apk is not compatible with 16 KB devices. Some libraries have LOAD segments not aligned at 16 KB boundaries:
lib/arm64-v8a/libnode.so
lib/arm64-v8a/libnodejs-mobile-react-native-native-lib.so
Starting November 1st, 2025, all new apps and updates to existing apps submitted to Google Play and targeting Android 15+ devices must support 16 KB page sizes. For more information about compatibility with 16 KB devices, visit developer.android.com/16kb-page-size.

I managed to fix the "lib/arm64-v8a/libnodejs-mobile-react-native-native-lib.so" issue in the build.gradle

android
      defaultConfig {
         externalNativeBuild {
             cmake {
-                cppFlags ""
+                // Enable 16KB page size for Android (NDK r27+)
+                arguments "-DANDROID_SUPPORT_FLEXIBLE_PAGE_SIZES=ON"
                 if(!_isCorrectSTLDefinedByApp) {
                     arguments "-DANDROID_STL=c++_shared"
                 }

but we also need correct versions of the lib/arm64-v8a/libnode.so libraries to get rid also of the other issue.
Can anyone help me on how to generate this libnode.so with 16KB support ?

Anyway an update of the library is required with a fix before the 1st of November or we will not be able to submit or update apps in google play store.

@staltz I saw that the library changed how the libraries are built. I see that they appear in libnode/bin folder when the library Is installed in a project., but I don't get where is the configuration that is used to build them.

Thanks a lot for you support
