#Android11
Android migrates away from C/C++ to Java/Kotlin/Rust
In Android 12 we announced support for the Rust programming language in the Android platform as a memory-safe alternative to C/C++. Since then we’ve been scaling up our Rust experience and usage within the Android Open Source Project (AOSP).
In Android 13, about 21% of all new native code (C/C++/Rust) is in Rust.

12L and new Android APIs and tools for large screens
Announced a preview of a special version of Android 12 for devices with large screens: tablets, foldable and Chrome OS - Android 12L (L - large as I understand it).In this version, the UI of the system for large devices has been updated, multitasking has been improved, new taskbar, etc.
Android 12L will be release early 2022. Google recommends adapting the applications, but it will not be mandatory to be published on Google Play.
In addition, the Material Design manual has been updated, and an API has been added for developing universal applications for various screen sizes. Now you can embed Activity (Activity embedding), Window size classes (will appear in Jetpack Window 1.1) and other possibilities for folding devices.
An interesting innovation is resizable emulator that can change screen size on the fly: phone, tablet (portrait and landscape), folding device
