How to migrate to 16 KB pages

YACINE REZQUI: Hello, my name is Yacine Rezqui, and I'm a developer relations engineer on Android.

Today, I'll tell you everything to know to migrate your app to be compatible with 16 KB memory page sizes.

But first, let me explain to you what's memory page and how we'll program access memory.

When your app reads or writes variables, it stores them in a volatile memory, known commonly as physical memory or RAM.

To simplify its organization and reduce waste space, data is stored in a fixed size block, and we call this block a memory page.

And on Android, historically, there are 4 KB each.

And when an app needs more memory, more memory pages will be allocated.

Each memory will have its own physical address to locate it inside the physical memory.
