16 KB page size incompatibility persists in AAR (libmodpdfium.so / libmodft2.so / libmodpng.so) despite README claim

Hello maintainers,

Thank you for your work on AndroidPdfViewer and for addressing the upcoming Android 15 / Google Play 16 KB page size requirement.

However, after integrating the current published artifact, I am still encountering Google Play 16 KB page size compatibility errors, specifically related to native libraries bundled in the AAR.

Environment

Library: com.github.barteksc:android-pdf-viewer:3.2.0-beta.1

Target SDK: Android 15 (API 35)

ABI: arm64-v8a

Build type: Release

Distribution: Google Play Console validation

Issue Description

Google Play reports the following error during upload:

"is not compatible with 16 KB devices. Some libraries have LOAD segments not aligned at 16 KB boundaries:"

lib/arm64-v8a/libmodft2.so lib/arm64-v8a/libmodpdfium.so lib/arm64-v8a/libmodpng.so

This results in the app being rejected for Android 15+ devices.

Investigation Results

The above .so files are bundled directly by android-pdf-viewer

File sizes are very small (~4 KB), suggesting stub or improperly built native binaries

Google Play’s 16 KB validation explicitly flags these libraries

No other native libraries are included in the app

Removing android-pdf-viewer removes the issue entirely

Expected Behavior

According to the README in this repository, 16 KB page size support is claimed to be fixed for Google Play compliance (Nov 1, 2025 requirement).

I would expect:

Native .so files to be rebuilt with proper alignment (e.g. -Wl,-z,max-page-size=16384)

The published AAR to pass Google Play’s 16 KB validation without errors

Actual Behavior

The currently published artifact still fails 16 KB page size validation

Google Play Console rejects the app

No workaround is possible via Gradle packaging options, since this is a binary-level issue

Questions

Is the 16 KB fix only applied when building the project manually, but not yet reflected in the published AAR?

Is there a newer artifact or alternative Maven coordinate that includes the rebuilt native libraries?

If not, is there an ETA for a fully 16 KB–compatible release?

I’m happy to provide:

APK / AAB samples

Google Play Console screenshots

Output from 16 KB alignment validation scripts

Thank you for your time and clarification.

Best regards.
