libsqlcipher.so support 16 KB page sizes

[VEZE]

Hi guys, just wanted to flag that libsqlcipher.so hasn’t been updated yet to support 16KB page sizes.

As noted in Android's official guidance, support for 16KB pages will be required starting November 1, 2025, for native libraries.

Would it be possible to prioritize this migration? We're trying to stay ahead of the deadline, and this is currently a blocker for us.

Hi @VEZE,

The sqlcipher-android project added support for 16 KB page sizes in the 4.6.1 release, the latest release is 4.9.0. Please consider updating your library version.

We are using net.zetetic.:sqlcipher-android:4.8.0 where libsqlcipher.so is not compiled with 16KB page size. Are you sure it was supported in 4.6.1?

The libsqlcipher.so files from sqlcipher-android 4.8.0 are all compiled with 16KB page size as shown below. Please explain exactly where you are seeing otherwise.

it seems I was operating with an outdated build, I rechecked and indeed 4.8.0 is compiled with 16kb of page size. Sorry for the inconvenience. 🤦
