Mac和“恐慌：缺少”ARM“CPU的模拟器引擎程序。”

Question

我正在尝试在Galaxy Nexus上运行我为API 16创建的AVD：

emulator @Galaxy_Nexus_Jelly_Bean_API_16

这会给出错误

恐慌：缺少“ARM”CPU的模拟器引擎程序。

我看过其他有类似问题的帖子。大多数人认为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：

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，仿真器和特定于体系结构的仿真器也在android_home下：

我不知道还有什么地方可以找，要么是错误消息，要么是系统找不到的模拟器，要么是解决问题的其他方法。

更新1：显式指定路径。

尝试显式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，未定义android_sdk_root。将其定义为与android_home相同的内容会执行以下操作：

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，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

Answer 1

刚刚在我的Mac上进行了尝试和验证，要解决这个问题，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
