Prepare your Play app for devices with 16 KB page sizes

So I suppose we just update to the latest tools for compilation and no need for @Erel to change code creation. Maybe just a lifting in compile shell commands. Right?

It looks like no change is needed unless you are using a library that includes a native (.so) binary. There aren't many.

Specifically if you are using SQLCipher then you need to remove it: https://www.b4x.com/android/forum/threads/libraries-that-do-not-support-16-kb.167832

I have some apps with Offline databases that are protected using the sqlcipher... meaning I have to change them to normal database or find a way to protect the information they contained....

 

[aeric]

So far I don't get any email from Google that my apps are having libraries that not compatible with the 16KB pages.

You wont get Email, You will see it When you logon to your Play Console, and open the App page, then click Test and Release

You can use plain SQLite DB with your own cipher to cipher/decipher the data. There is no difference between SQLCipher and SQL Plain with your own cipher since either way (even if obfuscated) the keys are most likely hard typed in your code.

I checked. Only thing I need to change is target SDK set to API 35 by Nov 1.

I just receive this email.

Your app is affected by Google Play's 16 KB page size requirements​

To ensure your app works correctly on the latest versions of Android, Google Play requires all apps targeting Android 15+ to support 16 KB memory page sizes. From May 1, 2026, if your app updates do not support 16 KB memory page sizes, you won't be able to release these updates.​

Yes the emails and notifications are now going out

Thanks for the tip.

But it doesn’t explain how to identify the affected libraries.
My app uses 42 of them.

Does anyone know a tool to analyze APKs for the 16k problem?

Script to check compatibility 16kb

As the title suggests, here's a script to check 16kb compatibility (for those who don't use Android Studio's APK Analyzer). The script analyzes apk, aar, aab or zip files. You need to download and unzip android-ndk-r28c-windows.zip, which you can find at this link: (...
