Hello,

with Android 15 the page size of memory is changed to 16GB.

Could any issue with new page size?

Thanks

Why should be there an issue? The only "issue" is higher memory consumption. And by default Android 15 uses 4KB pages, you have to build Android by yourself to enable 16KB page size.

I thought it is transparent for us.

in this section https://developer.android.com/guide/practices/page-sizes?hl=en

...
If your app uses any native code, then you should rebuild your app with support for 16 KB devices. If you are unsure if your app uses native code, you can use the APK Analyzer to identify whether any native code is present and then check the alignment of ELF segments for any shared libraries that you find.

..

But I don't understand if it is mandary where devices are page size 16KB.
