At Google I/O this year, we talked about how your app can take advantage of Android’s different screens, both large and small. But if you missed the show, here are the top things you should know:
Tablets, Foldables, and Large Screens
It’s more important than ever to design your app to work well on large screens — including tablets, foldables, and Chrome OS laptops. There are already over 250 million large screen Android devices in use today. Meanwhile, new foldable devices are making it easier for users to multitask, and opening up new experiences like tabletop mode for hands-free activities. See this example of Disney+ using tabletop mode on the Samsung Galaxy Z Fold2.
Fortunately, it’s also easier than ever to design apps which seamlessly scale to adapt to any device size — including dynamically resizing on Chrome OS and foldable devices, taking advantage of Jetpack Compose or ConstraintLayout to build responsive layouts. We also studied how people interact with large screens, like where their fingers are placed, and we’re giving you APIs and Tools to make that experience easier:
We’ve also made updates to the Android platform, Chrome OS, and Jetpack WindowManager, so apps just work better by default. For example, many UI elements now have default Max Width values to make sure they look better on large screens, while changes to the Display API ensure that existing apps continue to render correctly on foldables even if they aren’t using WindowManager to query window metrics.

We announced our biggest update yet to the Wear platform, with new features, APIs and tools to help developers create beautiful, high quality wearable experiences.
There are new Jetpack APIs to help you streamline your development. The Tiles library gives users fast, predictable access to the information and actions they rely on most. Another notable addition is the Ongoing Activities API, which enables you to let your users return to your app after they’ve navigated away (to start some other task such as music playback). Both of these libraries are currently in alpha.
We also released a new set of APIs for health and fitness that act as an intermediary to the sensors and related algorithms on the device to provide apps with high-quality data related to activity, exercise, and health. The alpha of the Health Services platform is available to use today.

Android TV OS now has over 80 million monthly active devices, with 80% growth in the US and is at the heart of the Google TV experience launched last fall. Meanwhile, Google TV itself can be found on streaming devices like the Chromecast with Google TV, smart TVs from Sony, and as an app on Android devices — including tablets.
This year at I/O, we announced several new tools and features to make developing for Android TV OS easier:
- Cast Connect with Stream Transfer allows moving existing audio and video streams between cast devices, while Stream Expansion allows playing audio on multiple devices simultaneously.
- We are now making our first Google TV Emulator available alongside the Android TV emulator, both running on Android 11.
- Firebase Test Lab is adding Android TV support, letting you test your app in the cloud across hundreds or thousands of virtual devices. Physical Devices will be coming soon.
- We are making the Android 12 Beta 1 available for TV on ADT-3 today.
These releases make it easier to build and test applications across a range of device configurations, while bringing the latest Android 12, Googler Assistant, and Cast features to the TV. To learn more, watch the What’s new in Android TV and Google TV session from I/O.
Android for Cars
Android Auto allows applications to connect with the infotainment displays built into many modern vehicles. To make this even easier we recently made the Android for Cars App Library available as part of Jetpack. This library allows navigation, EV charging, and parking apps to integrate directly with compatible cars.
We plan to expand to more app categories in the future, so if you’re expressing interest in bringing your app to Android Auto please fill out this interest form. You can also get started with the Android for Cars App Library today, by visiting g.co/androidforcars. Watch the What’s new with Android for Cars session from I/O for even more detail, or the accompanying What’s new with Android for Cars blog post.
