刚刚在 Mac 上更新到 Android Studio 4.2.1，现在模拟器不再工作
Just updated to Android Studio 4.2.1 on Mac and now emulator no longer works
我刚刚将 Android Studio 更新到最新版本 4.2.1，模拟器停止工作。每次我尝试启动新的虚拟设备时它都会崩溃，AVD 管理器会向我显示此错误：
“AVD Pixel_C_API_30 的模拟器进程已被终止”
这是我目前尝试过的方法：
冷启动重启。
删除并重新创建了 AVD 管理器中的虚拟设备。
删除并重新安装模拟器 SDK 包（版本 30.7.4）
退出并重新启动 Android Studio 以及模拟器。
从头创建了一个新的虚拟设备。
尝试了几种不同的虚拟设备。
以上所有都给我完全相同的结果：模拟器崩溃，AVD 管理器向我显示上述错误。
这是我从 MacOS 得到的错误（只是其中的一个摘录）：

有什么想法吗？我使用的是 MacOS 10.15.6，Android Studio 版本 4.2.1，运行时版本：11.0.8+10-b944.6916264 x86_64
更新：我试过像这样从终端启动它：
./emulator -avd Pixel_C_API_30
我在崩溃前得到了以下输出：

我遇到了完全相同的错误。这是由 Android Emulator 30.7.4 与 macOS Catalina 结合使用引起的。您可以在此处跟踪问题
对我有用的解决方法是升级到 Big Sur。
您可以下载模拟器并将其放入SDK文件夹中。它对我有用。在这里我找到了文件。
我手动恢复到 30.6.5，它又恢复了。
您必须为 Catalina 降级模拟器
- 下载模拟器30.7.3
- 解压emulator-darwin_x64-7425822.zip
- 执行命令“xattr -rc *”删除所有扩展属性
- 替换您的模拟器文件夹(/Users/xxx/Library/Android/sdk)
- 修改package.xml为
<revision><major>30</major><minor>7</minor><micro>3</micro></revision>
借助这个 可以将版本降级到 v30.6.5；现在可以 运行 模拟器
所有的答案都令人困惑，无法理解。更换SDK或升级OS。我发现最快的方法是：
工具 > SDK 管理器 > SDK 工具
De-selectAndroidEmulator，然后点击Apply。 - Android 模拟器将被删除。
现在，默认显示的模拟器版本为 30.6.5。 Select 复选框并单击应用。将安装此版本的模拟器。
就是这样，只占用您 2 分钟的时间。
更新：2021 年 7 月 1 日
最新的模拟器版本 30.7.5
解决了这个问题
我把版本降到v30.9.4了，还是报错：
“AVD xxx 的模拟器进程被终止”
然后我发现我可以通过命令行启动模拟器：
cd /Users/jinlei/Library/Android/sdk/emulator
./emulator -list-avds
./emulator -avd Pixel_2_API_Sv2
但是从IDE开始，这个错误还是出现了。
我刚刚将 Android Studio 更新到最新版本 4.2.1，模拟器停止工作。每次我尝试启动新的虚拟设备时它都会崩溃，AVD 管理器会向我显示此错误：
“AVD Pixel_C_API_30 的模拟器进程已被终止”
