Today’s Beta 1 build includes improvements to functionality and user experience as well as the latest bug fixes, optimizations, and the December 2021 security patches. For developers, we’ve finalized the APIs early, so Beta 1 also includes the official 12L APIs (API level 32), updated build tools, and system images for testing. These give you everything you need to test your apps with the 12L features.
With 12L, we’ve focused on refining the UI on large screen devices, across notifications, quick settings, lockscreen, overview, home screen, and more. For example, on screens above 600dp, the notification shade, lockscreen, and other system surfaces use a new two-column layout to take advantage of the screen area.
Two-column layouts show more and are easier to use
Multitasking is also more powerful and intuitive – 12L includes a new taskbar on large screens that lets users instantly switch to favorite apps on the fly or drag-and-drop apps into split-screen mode. Remember, on Android 12 and later, users can launch any app into split screen mode, regardless whether the app is resizable. Make sure to test your apps in split screen mode!
Drag and drop apps into split-screen mode
Last, we’ve improved compatibility mode with visual and stability improvements to offer a better letterboxing experience for users and help apps look better by default. If your app is not yet optimized for large screens, make sure to test your app with the new letterboxing.
Get started with 12L on a device!
12L is coming to phones, too, and although you won’t see the large screen features on smaller screens, we welcome you to try out the latest improvements in this feature drop. Just enroll your supported Pixel device here to get the latest 12L Beta update over-the-air. If you are still enrolled in the Android 12 Beta program, you’ll automatically receive the update 12L.
