Note: As we announced late last year like that, we have changed the version numbering scheme to match the number IntelliJ IDE Android Studio is based, namely 2020.3, combined with our own patch number, and an easy to remember and use The code name. We will arrange the code names in alphabetical order. The first one is Arctic Fox, which is now in Beta; the next code name is Bumblebee, which is still in the Canary channel.

Now, we are happy to announce to you Android Studio Arctic Fox (2020.3.1) Beta ❄️ 🦊: The latest version of the official Android IDE, focusing on design, equipment and developer productivity. You can download it now in the Beta channel to try out all the new features released during Google I/O 2021:

Despite having to adapt to various challenges in the past year, developer communities around the world continue to create amazing and innovative applications. Thanks to feedback from the community, we have provided and updated this set of tools for everyone, aiming to empower three themes:

  • Quick UI Design -With Jetpack Compose , creating a modern UI has never been easier. We provide various tools to help you complete the design journey: create previews in different configurations, use Compose Preview to navigate your code, use Deploy Preview to Device for individual testing, and use Layout Inspector to inspect the entire application. Throughout the iteration process, you can quickly edit strings and numbers and see instant updates. In addition, through the Accessibility Scanner in the Layout Editor, you can check whether there are accessibility issues in the View-based layout.
  • covers new devices, regardless of size -expand your application to a broader stage, not just limited to mobile phones. Whether it is Wear OS, Google TV or Android Auto, we have prepared new emulators and system images, and even real simulations for different test scenarios: Use Wear OS Pairing to pair your watch and mobile phone emulator, use Wear OS The heart rate sensor performs a virtual run, uses Google TV Remote Control to switch channels, and uses Automotive OS Sensor Replay to drive.
  • enhances developer productivity -We want to ensure that your workspace and environment are prepared for the latest system, and optimized for speed and quality. Now, you can enjoy a large number of new features and improvements brought by the major update of Intellij 2020.3, test the new features brought by Android 12 in the app, use the new UI of Memory Profiler to improve app performance, and use WorkManager Inspector to clarify the relationship between background tasks , And use Non-Transitive R-like IDE Refactoring to improve the construction speed.

In short, this is an upgrade not to be missed! ✨ Around these themes, there are many features and improvements in the Beta version for you to experience, please continue to read this article or watch the following speeches to learn more about the highlights.

Below is a complete list of new features in Android Studio Arctic Fox (2020.3.1) Beta, organized by three themes:


  • Compose Preview -Use Compose Preview to create a preview of the Compose UI! By using the @Preview annotation, Compose Preview can visualize multiple components at a time in different configurations (ie, themes, devices), and create a mental map for you to navigate your code.

△ Compose Preview

  • Compose Layout Inspector -You can now use the Layout Inspector to inspect layouts written in Compose. Whether your application is a layout written entirely in Compose, or a mix of Compose and View, Layout Inspector can help you understand how the layout is presented on the device or simulator, and get rich details (such as the parameters passed to each Composable And modifiers), and debug possible problems. When you interact with the app, you can now also choose to enable Live Updates (Live Updates) to continuously stream data from your device, or disable real-time updates and use refresh (Refresh) Actions to reduce the impact on the performance of the device.

  • deployment preview to device -Use this feature to deploy UI fragments to a device or simulator, so you can test a small part of your code on the device without launching the full application. Your preview will get the same operating environment (permissions, resources) as the application. Just click the Deploy to device icon, which is located at the top of the Compose preview or next to the @Preview comment in the gutter bar of the code editor, and Android Studio will deploy the @Preview to the connected device or emulator.

△ Pay attention to the deploy to device button in the preview and editor gutter bar

  • character real-time editing -The real-time editing function of characters allows developers using Compose to quickly edit characters (strings, numbers, Boolean operations) in the code and see the results immediately without waiting for compilation. This feature improves your productivity by allowing code changes to be reflected in the preview, simulator, or physical device almost instantly.

  • Accessibility Scanner in Layout Editor -Android Studio is now integrated with Android Accessibility Test Framework to help you discover accessibility issues in layouts. When using the Layout Editor, click the error report button to view this panel. Accessibility Scanner (Accessibility Scanner) will report problems related to accessibility and recommend fixes for common problems (such as missing content description, or low contrast, etc.).

  • Update system requirements -To ensure that we provide the best experience for Android developers, we have updated the system requirements for using Android Studio. These requirements also represent the configuration we used to thoroughly test Android Studio to ensure high quality and high performance, and we plan to update these requirements more frequently in the future. Although you can still use the system below the configuration requirements, we cannot guarantee compatibility or support when doing so. Please go to the official developer website check the updated system requirements.
