简单的解决方案:

打开Android Studio工具菜单， SDK管理器在窗口中出现 上面是内嵌板， 选择SDK工具面板勾选Android SDK命令行工具 选择窗口底部附近的Apply按钮

同样的问题，通过谷歌来的。 根据AndroidStudio Archive，今天是4.1版本的发布日。 我想这不是巧合。

这个完全不相关的指南有一个针对linux的老版本sdk-tools的硬链接。 对于其他操作系统，可以将url更改为windows或mac。我现在就用它来解决问题。

(这应该是一个评论而不是一个解决方案)

我们不再为每个命令执行传递参数——sdk_root，而是深入研究真正的原因。

Starting from Android SDK Command-line Tools 1.0.0 (6200805), in contrast to Android SDK 26.1.1 (4333796), the tools directory hierarchy has been changed. Previously it was placed right inside ANDROID_HOME (which is deprecated, we will use the term ANDROID_SDK_ROOT for the rest of the paragraph), now it's still named as tools (the only thing you'll get after unpacking the downloaded commandlinetools zip file), but differently, you have to place it inside a directory called cmdline-tools on your own. The name cmdline-tools comes from its package name, where you can get from listing packages command sdkmanager --list, whose outputs include cmdline-tools;1.0 | 1.0 | Android SDK Command-line Tools.

将tools目录包装到cmdline-tools目录中将使其工作，并帮助您摆脱恼人的——sdk_root参数。但是其他部分呢?

这就是你要改变的。让我解释更多。

The king - sdkmanager lives inside cmdline-tools/tools/bin, you'd better set in PATH environment variable cmdline-tools should not be set as ANDROID_SDK_ROOT. Because later, when updating Android SDK, or installing more packages, the other packages will be placed under ANDROID_SDK_ROOT, but not under cmdline-tools. The final, complete ANDROID_SDK_ROOT directory structure should look like below, consist of quite a few sub-directories: build-tools, cmdline-tools, emulator, licenses, patcher, platform-tools, platforms, system-images. You can easily point out that build-tools and cmdline-tools are siblings, all sit inside the parent ANDROID_SDK_ROOT.

让我简单概括一下:

设置您首选的ANDROID_SDK_ROOT(就像以前一样) 下载并解压commandlinetools zip文件到名为cmdline-tools的目录中，该目录位于ANDROID_SDK_ROOT目录中 将目录$ANDROID_SDK_ROOT/cmdline-tools/tools/bin追加到环境变量PATH后，这样系统就知道在哪里可以找到sdkmanager

更新! ! ! !

自构建6858069 (Android SDK命令行工具3.0)以来，行为再次发生了变化:

After unzipping the package, the top-most directory you'll get is cmdline-tools. Rename the unpacked directory from cmdline-tools to tools, and place it under $ANDROID_SDK_ROOT/cmdline-tools, so now it should look like: $ANDROID_SDK_ROOT/cmdline-tools/tools. And inside it, you should have: NOTICE.txt bin lib source.properties. Actually according to the official Command-Line Tools doc, the tree structure should be android_sdk/cmdline-tools/version/bin/, but I've checked, using version or tools makes no difference here. For your environment variable PATH, I would recommend you to set like this: PATH=$PATH:$ANDROID_SDK_ROOT/cmdline-tools/latest/bin:$ANDROID_SDK_ROOT/cmdline-tools/tools/bin, because after update later, you'll get the latest sdkmanager placed under $ANDROID_SDK_ROOT/cmdline-tools/latest/bin, put it in front will make it higher priority.

这里总结了几篇有用的文章，对于想要快速片段的人，例如插入Dockerfile，下面的脚本对我来说很有用:

RUN mkdir -p /opt/android/cmdline-tools/latest \
    && cd /opt/android/cmdline-tools/latest \
    && wget https://dl.google.com/android/repository/commandlinetools-linux-6858069_latest.zip \
    && bsdtar --strip-components=1 -xvf commandlinetools-linux-6858069_latest.zip \
    && yes | bin/sdkmanager --licenses \
    && bin/sdkmanager "build-tools;29.0.2" "platforms;android-29" \
    && rm commandlinetools-linux-6858069_latest.zip

It just requires bsdtar to be installed (it's usually packaged in popular distributions). Android platform/build tools version 29 are installed, and Android sdk root will be then located in /opt/android. While this setup works for me without warnings as it is, I have an issue when reinstalling packages already installed, or possibly installing different version of the packages: it clashes with packages already present and create bogus directories in the sdk root, with -2, -3 suffixes. These directories are then ignored, and warnings like Observed package id 'emulator' in inconsistent location are printed, so this behavior is definitely not desirable. If you have a fix for that please write it in the comments or, if you are confident enough, just edit the script with the exact fix.

我想分享一下我的经验。

首先，我试图解释为什么目录结构必须看起来 在这个答案中显示的方法- https://stackoverflow.com/a/60460681/1758733。 https://stackoverflow.com/users/668455/tristan多次要求解释，所以希望我能澄清 下一个实验的情况:

1. unpack cmdline-tools to any path, for example c:\Android\tools;
2. create a folder for SDK, let it be c:\Android\SDK;
3. install cmdline-tools (yes, we install cmdline-tools again =)):
    c:\Android\tools\bin\sdkmanager --sdk_root=c:\Android\SDK "cmdline-tools;latest"
4. at this moment we can examine c:\Android\SDK and locate
    the path c:\Android\SDK\cmdline-tools\latest. If we compare
    this folder with the previous version c:\Android\tools we find out
    that they are identical. The new installed c:\Android\SDK\cmdline-tools\latest\sdkmanager works
    without --sdk_root argument so we could initially unpack cmdline-tools
    to cmdline-tools\latest.

可能会遇到另一个问题-卡在“.android/repositories.cfg无法加载”。

其他问题和事实:

1. QtCreator works with another sdkmanager that placed in SDK_ROOT/tools/bin
2. SDK_ROOT/tools/bin/sdkmanager works only with JDK 8
3. Java uses its own storage for certificates and it's not convinient usually.
    Thus one may want to use Windows certificate store. Unfortunately Grandle has the
    issue - https://stackoverflow.com/a/59056537 - so use the following:
    set JAVA_OPTS=-Djavax.net.ssl.trustStoreType=Windows-ROOT -Djavax.net.ssl.trustStore=NUL

总结一下Qt开发的配方可以组成:

1. download commandlinetools-win-6200805_latest.zip
2. extract cmdline-tools so there will be hierarchy
    SDKROOT
        - cmdline-tools
            - latest
                - bin
                    - sdkmanager.bat
                    - ...
                - lib
                - ...
3. install JDK 8. set JAVA_HOME=c:\path\to\java so that %JAVA_HOME%/bin/java.exe exists.
4. set JAVA_OPTS=-Djavax.net.ssl.trustStoreType=Windows-ROOT -Djavax.net.ssl.trustStore=NUL
5. NDK may be downloaded manually or installed with sdkmanager
6. install required components:
    SDKROOT\cmdline-tools\latest\bin\sdkmanager "tools" "build-tools;BUILD_TOOLS_VERSION" "platform-tools" "platforms;ANDROID_VERSION"
7. run qtcreator from console so JAVA_OPTS is taken into account (or set it globaly for windows user or even station)
8. tools -> options -> devices set paths to JDK 8, SDKROOT and NDK
