如何解决刚刚在 Mac 上更新到 Android Studio 4.2.1，现在模拟器不再工作
我刚刚将 Android Studio 更新到最新版本 4.2.1，但模拟器停止工作。每次我尝试启动一个新的虚拟设备时它都会崩溃并且 AVD 管理器向我显示这个错误：
“AVD Pixel_C_API_30 的模拟器进程被杀死”
这是我迄今为止尝试过的：
以上所有结果都给了我完全相同的结果：模拟器崩溃并且 AVD 管理器向我显示了上面的错误。
这是我从 MacOS 得到的错误（只是它的摘录）：

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：我试图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：
emulator: Android emulator version 30.7.4.0 (build_id 7453540) (CL:N/A)

解决方法
所有的答案都太混乱了，无法遵循。更换 SDK 或升级操作系统。我找到的最快方法是：
工具 > SDK 管理器 > SDK 工具
取消选择 Android Emulator，然后单击应用。 - 安卓模拟器将被删除。
现在，默认情况下显示的模拟器版本为 30.6.5。选中复选框并单击应用。将安装此版本的模拟器。
就是这样，只有 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 解决了问题
,我也有同样的错误。这是由 Android Emulator 30.7.4 与 macOS Catalina 结合引起的。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。
,您必须为 Catalina 降级模拟器
- 下载模拟器 30.7.3
- 解压模拟器-darwin_x64-7425822.zip
- 执行命令“xattr -rc *”删除所有扩展属性
- 替换你的模拟器文件夹(/Users/xxx/Library/Android/sdk)
- 将 package.xml 修改为
<revision><major>30</major><minor>7</minor><micro>3</micro></revision>
您可以下载模拟器并将其放入 SDK 文件夹中。它对我有用。我在这里找到了文件。 How to download android emulator without using android studio
,我手动恢复到 30.6.5，它又恢复了。
,借助此 link 能够将版本降级到 v30.6.5；现在可以运行模拟器了
