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

我找到了使用最新命令行工具的解决方案，以下步骤:

1 -将命令行工具提取到如下结构的文件夹: 例如:$ HOME /开发/ android / cmdline-tools /最新 (此文件夹必须包含lib, bin, notice.txt和source.properties)

2 -将ANDROID_HOME定义为环境变量:

ANDROID_HOME="$HOME/Development/android/cmdline-tools/latest"

3 -加载它的路径:

PATH="$PATH:$ANDROID_HOME/tools:$ANDROID_HOME/tools/lib:$ANDROID_HOME/tools/bin:$ANDROID_HOME/platform-tools"

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)

使用Android Studio的Ubuntu工作解决方案 下面是Ubuntu和Debian的工作过程:

install Android studio as desribed in their website https://developer.android.com/studio/install run : flutter config --android-studio-dir <location of android studio> then flutter config --android-sdk /home/user/Android/Sdk (this is the default location of the SDK) add the bin to your PATH PATH=$PATH:/home/user/Android/Sdk/tools/bin/ Afterwards, run : flutter doctor --android-licenses and accept all licences To check if everything is ok run the doctor in verbos mode as following : flutter doctor -v

Android Studio在安装命令行工具时是必要的，即使它不是你用来开发应用程序的编辑器。取消选中过时的包选项卡并下载工具就可以了;这应该可以解决许可证问题，你可以回到你最喜欢的IDE(如VS Code)。
