Mac 更新Android Studio问题

Tip:

在 Android Studio官网 下载最新稳定版本。官网更改了 Android Studio 的版本编号系统，以与IntelliJ IDEA（Android Studio 所基于的 IDE ）更加一致。

在之前的编号系统中，此版本的编号为 Android Studio 4.3 或版本4.3.0.1 。有了新的编号系统，现在是Android Studio - Arctic Fox | 2020.3.1 或2020.3.1 版本。

New version numbering

Updated version numbering for Android Studio

We have changed the version numbering system for Android Studio to more closely align with IntelliJ IDEA, the IDE that Android Studio is based on.

In the previous numbering system, this release would have been numbered as Android Studio 4.3 or version 4.3.0.1. With the new numbering system, it is now Android Studio - Arctic Fox | 2020.3.1, or version 2020.3.1.

Going forward, here’s how the Android Studio version number is determined:

...

• The first two number groups represent the version of the IntellIj platform that a particular Android Studio release is based on. For this release, it's version 2020.3.
• The third number group represents the Studio major version, starting at 1 and incrementing by one for every major release.
• The fourth number group represents the Studio minor/patch version, starting at 1 and incrementing by one for every minor release.
• We are also giving each major release a version name, incrementing from A to Z based on animal names. This release is named Arctic Fox.

Updated version numbering for Android Gradle plugin

We have changed the version numbering for Android Gradle plugin (AGP) to more closely match the underlying Gradle build tool. Therefore, AGP 7.0 is the next release after AGP 4.2.

For more details, see Versioning changes in the AGP release notes.

安装Android Studio后，在终端Terminal或者iTerm输入flutter doctor进行检查。
