Hello Zoom SDK / Developer Support Team,
I hope you are doing well.
I am reporting a critical issue regarding 16 KB memory page size support for the Android Zoom Meeting SDK.
Zoom Meeting SDK v6.5.10
To Reproduce
Integrate Zoom Meeting SDK v6.5.10 into an Android app.
Build an APK targeting arm64-v8a architecture.
Run the app on a Pixel 9 (Android 15 / API 36) device.
Confirm device memory page size:
adb shell getconf PAGE_SIZE
→ Output: 16384 (16 KB)
The app runs and joins meetings successfully (runtime compatibility works).
However, when checking native libraries via:
readelf -l libZoomMeetingBridge.so | grep -i align
or other alignment inspection tools like Google : https://cs.android.com/android/platform/superproject/main/+/main:system/extras/tools/check_elf_alignment.sh
it shows 4 KB alignment, meaning ELF binaries are not compiled for 16 KB page size.
Google Play Console still reports:
“Does not support 16 KB page size”, even though runtime behavior is fine.
Expected behavior
The Zoom SDK .so files (inside arm64-v8a) should be compiled with:
-Wl,-z,max-page-size=16384
so that ELF alignment matches 16 KB, ensuring Play Console validation passes.
Actual behavior
ELF binaries remain aligned to 4 KB.
Play Console flags the app as non-compliant under “Memory Page Size: Does not support 16 KB.”
Impact
Starting Nov 1, 2025, Google Play will block app updates targeting Android 15+ if native libraries are not 16 KB aligned.
Troubleshooting Routes
Tested latest v6.5.10 SDK — same issue.
Verified with sample app and production build.
Checked on multiple 16 KB devices (Pixel 9 / Android 15).
Confirmed runtime compatibility but compile-time ELF alignment still at 4 KB.
Smartphone / Device Info
Device: Pixel 9
OS: Android 15 (API 36)
Page Size: 16384 bytes (confirmed via adb shell getconf PAGE_SIZE)
Attachments
Screenshot: Pixel 9 terminal showing PAGE_SIZE = 16384
Screenshot: readelf output showing ELF alignment = 0x1000 (4 KB)
Screenshot: Play Console warning “Does not support 16 KB”
Requested Action
Please provide a Zoom Meeting SDK build with ELF binaries compiled for 16 KB alignment (-Wl,-z,max-page-size=16384).
Kindly share a timeline or ETA for when this fix will be released.
Please clarify if “16 KB page size support” in your changelog refers to:
Runtime compatibility only, or Full ELF binary compliance for Play Console verification.
Thank you for your time and support.
Best regards,
