Rebecca Franks, an Android Developer Relations Engineer at Google, announced the release of Jetpack Compose version 1.11 on April 24, 2026. The update brings significant enhancements to the modern Android UI toolkit, including new stable APIs and four large experimental APIs designed to empower developers with more flexible and performant UI creation. Franks highlighted the extensive new features and encouraged developers to provide feedback on the experimental additions.

The stable release of Compose 1.11 delivers several key improvements. Notable updates include a major overhaul to coroutine execution in tests, with v2 testing APIs now set as the default, promising more robust and less flaky test suites by better mimicking production conditions. Additionally, developers will benefit from new visual debugging tools for shared elements and revamped support for trackpad events, which now correctly interpret trackpad gestures as mouse events, improving user experience on various devices.

Among the most anticipated additions are four large experimental APIs. The new Styles API introduces a novel approach to customizing visual elements, moving beyond traditional modifiers to offer deeper, easier customization with state-based styling and animated transitions, potentially boosting performance. Complementing this is the MediaQuery API, providing a declarative and efficient method for UIs to adapt dynamically to their environment, such as device capabilities, window size, and posture, ensuring optimal display across diverse form factors.

For complex layout needs, Compose 1.11 introduces the experimental Grid and FlexBox APIs. Grid offers powerful control for two-dimensional layouts, allowing developers to define tracks, gaps, and cells for intricate screen architectures and components, with dynamic reconfiguration capabilities. FlexBox, on the other hand, is tailored for high-performance, adaptive UIs, efficiently managing item sizing and space distribution, and supporting advanced features like wrapping and multi-axis alignment to create highly responsive designs.

Franks' announcement underscored the continuous evolution of Jetpack Compose, stating in her tweet, > "#JetpackCompose version 1.11 has landed! So many new APIs to try out along with some important changes. We've also detailed 4 (!) new large Experimental APIs that we are actively looking for feedback on: 💅🏻 Styles! 🚥 Grid 💪🏻 FlexBox 🎞️ MediaQuery Let us know what you think!" The Google team is actively seeking community input on these experimental features to refine them for future stable releases, reinforcing Compose's commitment to developer-driven innovation.
