PowerSync native libraries not supporting 16 KB memory page size — causes Google Play Console rejection

[tareq-twinepos]

Hello PowerSync team,

We are encountering a critical issue when submitting our Android app to the Google Play Console. The submission is being rejected due to unsupported 16 KB memory page size in the PowerSync native libraries.

Google Play now requires all native libraries to support 16 KB memory page sizes, but the following PowerSync shared libraries do not meet this requirement:

base/lib/arm64-v8a/libpowersync.so  
base/lib/x86_64/libpowersync.so

The Play Console error message:

Memory page size does not support 16 KB
Libraries that do not support 16 KB:

base/lib/arm64-v8a/libpowersync.so

base/lib/x86_64/libpowersync.so

Impact

This issue blocks app submission entirely. The only reason for rejection is PowerSync’s .so files, so I am unable to publish or update the app on Google Play.

Request

Could you please:

Provide updated builds of libpowersync.so that support 16 KB memory page size, or

Confirm if there is an existing workaround or setting that enables 16 KB compatibility.

This is time-sensitive since Google Play no longer accepts binaries that don't meet this requirement.

Thank you!

Which version of the SDK art you using? As far as I know, we should be supporting 16KB page sizes for a while already

hi @rkistner, thanks for getting back. We are using the following
powersync: ^1.16.1
with Flutter version:
Stable 3.38.1
NDK:
29.0.13113456 rc1
AGP:
8.12.2
Gradle:
8.13

Could you also check the following?

1. The version of powersync_flutter_libs in your pubspec.lock (or run flutter pub deps) - this is the library that contains these libpowersync.so files. This should be 0.4.12.
2. Run the check_elf_alignment.sh script on those two libpowersync.so files (or the APK). This should show ALIGNED (2**14), but only for the arm64-v8a and x86_64 ones.
