带有“模拟器：错误：找不到SDK安装目录”的Android模拟器错误； [英] Android emulator errors with "emulator: ERROR: can't find SDK installation directory"

问题描述

我正在尝试在Windows（不带Android Studio）上从命令行安装和运行Android虚拟设备。我已经在C：\Android中设置了Android SDK，并使用以下命令成功创建了AVD：

  avdmanager create avd -n test -k系统图像； android-26； google_apis_playstore; x86 --abi google_apis_playstore / x86 
  

我将环境变量ANDROID_SDK_ROOT设置为C：\Android。

当我尝试从命令行启动仿真器时：

 模拟器@test 
  

我收到错误消息：

 模拟器：错误：找不到SDK安装目录
模拟器：找不到虚拟设备名为测试使用以下命令指定sysdir和datadir：
 模拟器@test -sysdir C：\Android\system-images\android -26\google_apis_playstore\x86 -datadir C：\Android\avd 
  
但我遇到相同的错误。
 
 
 
当我跑步时命令 avdmanager.bat list avd ，我得到：
 名称：test 
路径：C：\Android\avd\test.avd 
目标：Google Play（Google Inc.）
基于：Android API 26标签/ ABI：google_apis_playstore / x86 
  
为什么我不能运行AVD？
解决方案
我发现了问题。因为我试图通过命令行进行最小的Android SDK安装，所以我还没有Platform-tools文件夹。找不到平台工具文件夹导致模拟器显示无用的错误找不到SDK安装目录，这实际上意味着找不到平台工具目录。
 
 
 
一旦我用 sdkmanager --no_https platform-tools 安装了platform-tools文件夹，模拟器就可以工作了。我需要-no_https ，因为我处在残缺的公司环境中。
 
 
 
为了以后的参考，我安装了模拟器依赖项（从此处）解压缩sdk-tools-windows-3859397.zip之后） ：
  sdkmanager --no_https系统映像； android-26； google_apis_playstore； x86平台； android-26平台工具仿真器 
  
 
I am trying to install and run an Android Virtual Device from the command line on Windows (without Android Studio). I have set up an Android SDK in C:\Android, and successfully created an AVD with the command:
avdmanager create avd -n test -k "system-images;android-26;google_apis_playstore;x86" --abi google_apis_playstore/x86
I have environment variable ANDROID_SDK_ROOT set to C:\Android.

When I try to start the emulator from the command line with:
emulator @test
I get errors:
emulator: ERROR: can't find SDK installation directory
emulator: could not find virtual device named 'test'
I have also tried setting environment variables ANDROID_AVD_HOME and ANDROID_EMULATOR_HOME, and also tried running the AVD specifying sysdir and datadir with the command:
emulator @test -sysdir C:\Android\system-images\android-26\google_apis_playstore\x86 -datadir C:\Android\avd
but I get the same errors.

When I run command avdmanager.bat list avd, I get:
    Name: test
    Path: C:\Android\avd\test.avd
  Target: Google Play (Google Inc.)
          Based on: Android API 26 Tag/ABI: google_apis_playstore/x86
Why on earth can't I run the AVD?
解决方案
I found the problem. Because I was trying to do a minimal Android SDK install via the command line, I did not yet have a platform-tools folder. Not being able to find the platform-tools folder was causing the emulator to display the unhelpful error "can't find SDK installation directory", which really meant "can't find the platform-tools directory".

Once I installed the platform-tools folder with sdkmanager --no_https "platform-tools", the emulator worked. I need --no_https because I'm in a crippled corporate environment.

For future reference, I installed the emulator dependencies (after unzipping sdk-tools-windows-3859397.zip from here) with:
sdkmanager --no_https "system-images;android-26;google_apis_playstore;x86" "platforms;android-26" "platform-tools" "emulator"
