Wear OS 7.1 Canary Emulator Previews Persistent System Status Bar — Smartphones and mobile

Google's Wear OS 7.1 canary emulator previews a persistent system status bar for apps, with Jetpack Compose behavior for hiding and restoring it, though the feature will not be included in the upcoming stable Wear OS 7.1 emulator.

Google has outlined a forthcoming Wear OS feature that would add a persistent system status bar across app windows at the top of the circular display. The company said the bar will show the current time and system status indicators, similar to Android on phones and tablets. The indicators are designed to use standardized clock typography, placement and backplate across the platform and different apps, including third-party apps. Apps that need a fullscreen experience will be able to hide the status bar. In the current preview, the bar displays a placeholder star icon instead of the final system status indicators.

The feature is available for testing through a Wear OS canary emulator that Google released in Android Studio on Oct. 26. Google said the emulator lets developers test upcoming platform features and user interface changes before they become available in a consumer platform release on physical devices. The emulator is published as Wear OS 7.1, with API level 37.2-beta1, based on Android 17 "CinnamonBun," and build ID CP41.260831.001.E8.

For Jetpack Compose for Wear OS, apps targeting API level 35 or higher and compiling against Compose for Wear OS version 1.8.0-alpha02 or higher will automatically opt in to the system status bar through AppScaffold and ScreenScaffold. AppScaffold suppresses its in-app TimeText clock so that only the system status bar time appears. ScreenScaffold applies padding to the top status bar window inset, and the scaffold hides the status bar while users scroll through list content. After about two seconds of user idle time, the time text reappears. Full-screen interactive components in Wear Compose Material 3, including AlertDialog, Dialog, Stepper, TimePicker and DatePicker, automatically hide the system status bar while displayed. For screens that require a full-screen immersive experience, developers can use StatusBarSuppression.

Although the emulator carries the Wear OS 7.1 label, Google said the system status bar is included exclusively in the canary emulator to support early testing and feedback. It will not be included in the upcoming Wear OS 7.1 stable emulator, indicating that the status bar will launch in a later platform release.
