Android Studio Chipmunk | 2021.2.1 (May 2022)

The following are new features in Android Studio Chipmunk.

Support for creating your app with Jetpack Compose

Animation Preview supports animatedVisibility

Android Studio Chipmunk supports the animatedVisibility API in Animation Preview. To use Animation preview with animatedVisibility, use Compose version 1.1.0 or higher. To learn more about Animation Preview, see Animations.

Support for deploying preview from Library Modules

Previews allow you to view your UI within Android Studio without having to run your app on a physical device. In Android Studio Chipmunk, you can deploy a specific @Preview to an emulator or physical device from Library Modules. To learn more, see Deploy Preview.

Support for profiling your app

Detect jank on Android 12 and higher

For devices using Android 12 or higher, a captured trace is shown in the Janky frames track under the Display pane in the CPU Profiler.

To detect jank,

  1. From the development emulator or device, start the app.

  2. In Android Studio, select View > Tool Windows > Profiler or click Profile in the toolbar.

    If prompted by the Select Deployment Target dialog, choose the device to which to deploy your app for profiling. If you've connected a device over USB but don't see it listed, ensure that you have enabled USB debugging.

  3. Click anywhere in the CPU timeline to open the CPU Profiler.

  4. You should see the Janky frames track under Display. By default, the Profiler only shows janky frames as candidates for investigation. Within each janky frame, the red portion highlights the duration the frame takes past its rendering deadline. Screenshot of the Janky frames track

  5. Once you find a janky frame, click on it; optionally, you can press M to adjust the zoom to focus on the selected frame. The relevant events will be highlighted in the main threads: RenderThread and GPU completion. Screenshot of Profiler displaying Janky frames and main threads

  6. You can optionally see all frames or a breakdown of the rendering time by toggling the checkboxes All Frames and Lifecycle, respectively. Screenshot of Profiler as above but with All Frames and Lifecycle checkboxes checked

For more information, see UI jank detection.
