12L Developer Preview
Get ready for a special feature drop coming early next year that makes Android 12 even better on tablets and foldable devices. Try your apps on 12L and optimize for the next wave of large screen devices!
What’s in 12L?
An OS optimized for large screens
In 12L we’ve refined the UI to make Android more beautiful and easier to use on screens larger than 600sp — across notifications, quick settings, lockscreen, overview, home screen, and more. Try your app with the UI updates!
Built for multitasking
We’ve made multitasking more powerful and intuitive. 12L includes a new taskbar on large screens that lets users drag and drop an app into split-screen mode and instantly switch apps on the fly. Make sure your apps are ready for split-screen mode!
Improved compatibility experience
Visual and stability improvements to compatibility mode in 12L provide a better experience for users and help all apps look better by default. Test your apps to make sure they're optimized for large screens.
