See your app on Microsoft Surface Duo 2!

Hello Android developers!

Now that Surface Duo 2 is readily available, there’s even more reason to start enhancing your Android apps for foldable devices. Visit our developer documentation to get started!

Surface Duo 2 emulator

If you don’t yet have a device, you can easily build and test apps for Surface Duo 2 using our latest Android 11 emulator. Download and install the Surface Duo 2 emulator to test your apps in single and dual-screen modes, including adjustments based on hinge angle:

Jetpack Window Manager samples

Google provides the Jetpack Window Manager library and SlidingPaneLayout control for Android developers to adapt their apps for foldable and dual-screen devices. We’ve built a variety of samples to help Kotlin and Java developers learn how to use these APIs, as well as instructions for Jetpack Compose.

Developers using cross-platforms tools like Xamarin, Unity, React Native, Flutter, or web development can also build dual-screen and foldable-aware apps.

Design Kit 2.1

The Surface Duo Design Kit has also been updated. The Figma resource now includes Surface Duo 2 device frames, in addition to our user experience design guidelines, including:

• Design patterns such as list-detail, expanded canvas, dual view, two page, and companion pane
• Pen interaction guidance
• Video and media tips
• Safe areas, postures, controls, and layouts
• Components for prototyping

Develop in your language

Our dual-screen developer documentation is localized into a number of languages, including French, German, Japanese, Spanish, and more. We’re also adding translations to our samples so they’re more accessible to developers everywhere.
