The promise of Jetpack Compose has at all times been {that a} trendy toolkit designed to construct native UI might help you construct higher apps quicker and simpler. As an increasing number of of you – 40% of the highest 1k apps, in reality – use (and love) Compose, we’ve been working to increase these advantages you’re seeing on cellular to additionally aid you construct throughout kind components as properly. At Google I/O 2024, we introduced lots of new updates for Compose that aid you construct throughout kind components, together with Compose APIs to help adaptive layouts, and new updates for Compose TV and Put on OS. From foldables to wearables to TVs, Compose is delivering options constructed to make Android growth quicker and simpler. Apps like yours are already utilizing Compose to help extra screens with much less code.
Yesterday, we introduced a brand new set of Compose APIs for constructing adaptive layouts, utilizing Materials steering. These APIs, now in Beta, present new layouts and parts that adapt as customers count on when switching between small and enormous window sizes.
The libraries present 3 new scaffolds that adapt to the completely different window sizes that customers can place apps in on several types of units, from telephones to foldables to tablets and extra.
NavigationSuiteScaffold
helps make it simpler to construct navigation UI by robotically complying with Materials tips to supply your customers with an optimum expertise primarily based on their window dimension.
Materials tips suggest utilizing a navigation bar on the backside of compact width home windows reminiscent of most telephones and a navigation rail on the scale of medium width and expanded width home windows. It was as much as every app individually to deal with swapping between these parts; now NavigationSuiteScaffold does this for you by switching between the parts when the window dimension adjustments.
The brand new library additionally has ListDetailPaneScaffold and SupportingPaneScaffold, which aid you implement canonical layouts that we suggest in lots of circumstances – list-detail and supporting pane.
On a telephone, you normally arrange your app movement by way of screens. For instance, clicking on an merchandise in your record display brings you to the element display.
When adapting to completely different window sizes, it helps to think about your app when it comes to panes relatively than screens. For a compact window dimension class, reminiscent of a telephone, you may solely show one pane. For an expanded window dimension class, you may present two, or extra panes on the identical time. ListDetailPaneScaffold and SupportingPaneScaffold aid you construct apps that simply swap between one and two pane layouts.
You’ll be able to be taught extra about all three of those APIs and how one can get began with them within the “Constructing UI with the Materials 3 adaptive library” and “Constructing adaptive Android apps” technical periods.
“Integrating SupportingPaneScaffold was easy and fast. It enabled us to seamlessly arrange major and secondary content material on To-Dos. Relying on the window dimension class, the supporting pane adjusts the UI with none further customized logic. Delighting our customers no matter what system they use is a key precedence for SAP Cell Begin.”

Previously 12 months, adoption of Compose for Put on OS has grown 200%, showcasing the convenience with which Compose permits builders to construct for the watch kind issue.
Not too long ago we’ve seen high apps reminiscent of WhatsApp, Gmail and Google Calendar constructed totally utilizing Compose for Put on OS, and it’s the beneficial approach for constructing consumer interfaces for Put on OS apps.
At this 12 months’s Google I/O, Compose for Put on OS is graduating visible enhancements and fixes from beta to secure.
Previously 12 months, we’ve added options reminiscent of SwipeToReveal, to present customers further means for finishing actions, an expandableItem, to boost using the smaller display and present further data the place wanted, and a variety of WearPreview supporting annotations, for making certain your app works optimally throughout the vary of system sizes and font scales.
You may get began with Compose for Put on OS by taking the codelab and be taught extra about all the most recent updates for Put on OS by way of the technical session.
At Google I/O ‘24, we introduced that Compose for TV 1.0.0 is now accessible in beta. Compose for TV is our beneficial strategy for constructing pleasant UIs for Android TV OS.

We have now additionally launched new Canonical Widget Layouts on GitHub, that are constructed on high of the Look parts, to mean you can get began quicker with a set of layouts that align with greatest practices.
The primary set of layouts are delivered as code samples and an identical figma design package on Android UI Package with extra layouts coming later this 12 months.
Lastly, now we have new design steering printed on the UI design hub—test it out!
We have now up to date Jetcaster—one in all our Compose samples—to adapt throughout telephone, foldable and pill screens, and added help for TV, Put on and homescreen widgets with Look.
