Samsung's recent Galaxy Unpacked event introduced new foldable and wearable devices, expanding the variety of form factors and screen sizes developers must support. The Galaxy Z Fold8, with its landscape-first orientation and wider aspect ratio, presents new challenges for app layouts. Developers are encouraged to rethink their layout architecture to accommodate these dynamic displays, moving away from fixed assumptions about orientation and size. Key guidance includes building fluid, adaptive layouts that prioritize window class width and utilize flexible containers for content reflowing. Tracking actual app space using Jetpack Window Manager's Window Size Classes is crucial, especially in multitasking scenarios. The latest Jetpack Compose release offers new structural layout tools like Grid and FlexBox APIs for managing complex architectures and adapting UIs. Making apps fold-aware by using the Jetpack WindowManager library helps avoid placing crucial content over hinges and uses them as separators. Maintaining app continuity through ViewModel ensures seamless UI state retention during folding and unfolding. Camera implementations on foldables require migration to CameraX or integration with CameraViewfinder to handle sensor orientation and device rotation. Wear OS 7 introduces Wear Widgets, built with Jetpack Glance and RemoteCompose, allowing developers to create glanceable experiences for users' wrists. Finally, developers can leverage Gemini Nano 4 on Samsung devices and ML Kit's Prompt API to build intelligent, on-device features.
