Android Question Checked for 16kb compatibility

[Alex_197]

I checked my apk for 16kb compatibility with this script https://www.b4x.com/android/forum/threads/android-16kb-page-size-compatibility-checker.168942/

Here is a result

FINAL RESULT
= * 80
FAILED: 6 non-compliant file(s):
  - libc++_shared.so
  - libjniPdfium.so
  - libmodft2.so
  - libmodpdfium.so
  - libmodpng.so
  - libsqlcipher.so

I know that I need to upgrade my sqlcipher and pdfium. So my question is - based on the result what else has to be upgraded?

Thank you.

Required fixes:
1. Update to NDK 27+ which has proper 16KB alignment support
2. Add -Wl,-z,max-page-size=16384 to your linker flags
3. Recompile all native libraries
4. Contact third-party library vendors for 16KB-compatible versions

For gradle builds, add to build.gradle:
android.defaultConfig.ndk.abiFilters 'arm64-v8a'
android.defaultConfig.externalNativeBuild.cmake.arguments '-DANDROID_SUPPORT_FLEXIBLE_PAGE_SIZES=ON'
PS D:\16kb> exit

d:\16kb>

As you can see -the script sees android-ndk-r27d - so why it shows me these warnings ?

Thanks.
