新建項目向導 (New Project Wizard)

android studio、While creating a new application, there’s a different look of the project wizard and the activity template you choose.

創建新應用程序時，項目向導和您選擇的活動模板的外觀會有所不同。

You can select whether to use AndroidX or not as shown in the image below:

刪除未使用的IDE目錄 (Delete Unused IDE Directories)

In the past updates of Android Studio, it was difficult to locate and remove the caches, settings of old Android Studio versions. Now, when you update the IDE, it allows you to delete the older ones.

Android sdk、在過去的Android Studio更新中，很難找到和刪除舊Android Studio版本的緩存和設置。現在，當您更新IDE時，它允許您刪除較舊的IDE。

自動下載SDK組件 (Automatic Downloading of SDK Components)

When syncing a project if there are some missing components, Gradle now automatically downloads them provided that you had permitted this.

同步項目時，如果缺少某些組件，Gradle現在會自動下載它們，前提是您允許這樣做。

使用過時的API時更好的調試信息 (Better debug info when using obsolete APIs)

If your application is using obsolete APIs, Android Studio now provides more detailed debugging information on which part of your code is calling them. To enable this option, add the following line of code to a Gradle file:

如果您的應用程序使用的是過時的API，Android Studio現在會提供有關代碼的哪一部分調用它們的更詳細的調試信息。要啟用此選項，請將以下代碼行添加到Gradle文件中：

android.debug.obsoleteApi = true.

單版本構建同步 (Single Variant Build Sync)

android studio3.5.2安裝教程？If your project is configured with multiple build variants you can configure the IDE to sync only the active build thus saving lots of time.

如果您的項目配置有多個構建變體，則可以將IDE配置為僅同步活動的構建，從而節省大量時間。

Android Studio Single Build Variant Sync

Android Studio單一版本變體同步

Android捆綁包的即時應用 (Instant Apps for Android Bundles)

You can now create Instant Apps for Android App Bundles.

您現在可以為Android應用程序捆綁包創建Instant Apps。
