Mac和“PANIC：'arm'CPU缺少模拟器引擎程序。”

Question

我正在尝试运行我在Galaxy Nexus上为API 16创建的AVD：

emulator @Galaxy_Nexus_Jelly_Bean_API_16

这给出了错误

PANIC：缺少'arm'CPU的仿真器引擎程序。

尝试通过按下Android Studio内部AVD Manager的播放按钮启动它会在工具库中暂时弹出一些内容，但它会很快消失，没有任何显示，也没有明显的错误消息。

我查看了其他类似问题的帖子。大多数人都认为Windows上的Avast导致了这个问题。我在Mac上运行。我没有安装Avast。

AVD具有以下配置：

Android Studio环境：

Mac OS X 10.12.6

我已经为SDK Manager中提供的此版本SDK安装了所有内容：

我安装了最新版本的模拟器。我已经尝试卸载并重新安装它。

ANDROID_HOME环境变量似乎已正确设置（它与SDK Manager中的Android SDK location匹配.emulator程序似乎也是此家庭环境下的程序：

Mulan:~ prisoner$ echo $ANDROID_HOME
/Users/prisoner/Library/Android/sdk
Mulan:~ prisoner$ which emulator
/Users/prisoner/Library/Android/sdk/tools/emulator

据我所知，模拟器和体系结构特定的模拟器也在ANDROID_HOME下：

我不知道在哪里可以查看错误消息或那里的模拟器，但系统无法找到，或者如何解决问题。

更新1：显式指定路径。

尝试明确指定路径也不起作用：

Mulan:~ prisoner$ /Users/prisoner/Library/Android/sdk/tools/emulator @Galaxy_Nexus_Jelly_Bean_API_16
PANIC: Missing emulator engine program for 'arm' CPU.
Mulan:~ prisoner$ /Users/prisoner/Library/Android/sdk/emulator/emulator @Galaxy_Nexus_Jelly_Bean_API_16
emulator: ERROR: This AVD's configuration is missing a kernel file! Please ensure the file "kernel-qemu" is in the same location as your system image.
emulator: ERROR: ANDROID_SDK_ROOT is undefined

果然，ANDROID_SDK_ROOT没有定义。将它定义为与ANDROID_HOME相同的内容执行以下操作：

Mulan:~ prisoner$ export ANDROID_SDK_ROOT="$ANDROID_HOME"
Mulan:~ prisoner$ /Users/prisoner/Library/Android/sdk/emulator/emulator @Galaxy_Nexus_Jelly_Bean_API_16
emulator: ERROR: This AVD's configuration is missing a kernel file! Please ensure the file "kernel-qemu" is in the same location as your system image.
emulator: ERROR: ANDROID_SDK_ROOT is defined (/Users/prisoner/Library/Android/sdk) but cannot find kernel file in /Users/prisoner/Library/Android/sdk/system-images/ sub directories

在system-images目录下面，我们看到每个API平台的目录：

Mulan:~ prisoner$ ls ~/Library/Android/sdk/system-images/
android-16  android-19  android-23  android-26
android-17  android-21  android-24  android-27
android-18  android-22  android-25  android-28

看看android-16目录下，我们有

Answer 1

只是在我的Mac上尝试并验证，要解决此问题，您需要手动指定-kernel路径。即

$ ~/Library/Android/sdk/emulator/emulator  @Galaxy_Nexus_Jelly_Bean_API_16 -kernel ~/Library/Android/sdk/system-images/android-16/default/armeabi-v7a/kernel-qemu

一些参考资料：

1. Emulator error: This AVD's configuration is missing a kernel file
2. https://developer.android.com/studio/run/emulator-commandline

---编辑---

为避免每次都输入-kernel参数，您还可以将~/Library/Android/sdk/system-images/android-16/default/armeabi-v7a/kernel-qemu文件复制到~/Library/Android/sdk/add-ons/addon-google_apis-google-16/images/armeabi-v7a。

Answer 2

也许这是模拟器工具路径问题。尝试指定模拟器路径的完整路径。
