Update native .so files to support 16 KB page size for Android 15+ devices [Deadline- November 1st, 2025]

[IMRISHABH08]

❓ Add Support for 16 KB Page Size for Android 15+ devices

• While verifying the alignment between our Flutter app and the native dependencies (.so files) for the 16KB Page Size update, we’ve identified an issue with the native libararies bundled in flutter_cached_pdfview.
• When inspecting the .so files in the generated .aab with your SDK(latest: 1.10.6), we found that several native libraries are built with a Page size 0x1000 = 2¹² (4 KB) instead 0x4000 = 2¹⁴ (~16 KB). This mismatch is preventing our Flutter app from fully supporting the 16KB page size requirement.

- UNALIGNED .so files from flutter_cached_pdfview where Page Size 0x1000 = 2¹² (4 KB)

• armeabi-v7a, arm64-v8a, and x86_64

.so files	UNALIGNED ELF	.aar & .so file mapping
libjniPdfium.so
libmodpdfium.so
libc++_shared.so
libmodft2.so
libmodpng.so

• Script to check ELF Alignment

• Solution

• For detailed mapping b/w .aar and .so files run this command from your home directory(MacOS).
  cd ~/.gradle/caches/modules-2/files-2.1 find . -name "*.aar" -exec sh -c 'echo {}; unzip -l "{}" | grep "\.so"' \;

• flutter_cached_pdfview: 0.4.3

  • Flutter version 3.27.3 on channel stable
  • Dart version 3.6.1

any update on it

[TheoBodmer1]

We have the same issue here and would greatly appreciate it if the package could be updated.

[TheoBodmer1]

The underlying package flutter_pdfview seems to have a beta version (1.4.2-beta.1) that should be compatible with the new 16 kb page size requirement.
I have not tested it yet.

@binSaed

Any new here?
Thanks.

Fot now you can use "pdfrx" which supports 16kb.

Any update ?

@IMRISHABH08 I created a PR for this, it just updates the flutter_pdfview dependency to version 1.4.2-beta.1 to add support for 16KB page sizes and I don't get the warning anymore. You can use this update by changing your pubspec to reference my version until the PR is merged or @binSaed publishes his update of the package.

  flutter_cached_pdfview: 
    git:
      url: https://github.com/JoelOvien/flutter_cached_pdfview.git
      ref: master

Note: The flutter_pdfview currently supports 16KB page size in it's beta release (currently not an issue as the maintainers are asking everyone to use that for now)

It seems that the package owner is no longer maintaining this package. However, the actual issue lies in the underlying dependency flutter_pdfview, specifically in versions prior to 1.4.2-beta.1.
You can resolve the problem by updating flutter_pdfview to 1.4.2-beta.1 or higher (better to 1.4.3 or higher, since that’s a stable release).
To do this, run the following command:

flutter pub upgrade flutter_pdfview

This will update the flutter_pdfview version in your pubspec.lock file to the latest compatible release (currently 1.4.3), within the acceptable range (>=1.0.0 <2.0.0). This should fix the issue.

I did the upgrade and still the alignment issue seems to be there

[TimurDyushaliev]

@rubinbasha which native libs are causing the issue?

Worked for me thanks @TimurDyushaliev !

@TimurDyushaliev This worked thanks ! Verified from the Play Console.
