关于android_SDK_ROOT的Android studio虚拟设备错误

Question

I need to use the android stdio to develop some app, BUT when I try to open the virtual device, it has some problem.

Cannot launch AVD in emulator.
Output:
emulator: WARNING: Crash service did not startemulator: 
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

I already found some solutions about this error, ie. the intel x86 haxm, SDK version, install the jave JDK8... but it's not work yet....What happen about this problem??

Answer 1

I had this problem when I tried to run without any x86 image. You can see here when running the SDK Manager:

It worked after the installation of the missing x86 image.

Disclosure: I got this image from another SO post .

Answer 2

你必须先下载系统映像。
