Comments

As per the link https://developer.android.com/guide/practices/page-sizes Starting November 1st, 2025, all new apps and updates to existing apps submitted to Google Play and targeting Android 15+ devices must support 16 KB page sizes on 64-bit devices. Note that Android apps are already required to target Android 15 as a minimum, so basically there is a hard deadline to have apps supporting 16 KB page sizes by Nov 1st (assuming you didn't request for an extension).

No workaround other than rebuilding source code yourself.
