无法找到android-sdk

Question

我在Ubuntu21.04上，从这里下载命令行工具：https://developer.android.com/studio#downloads。

我遵循这个指南来设置没有Android：https://dev.to/ejgamer21/install-flutter-without-android-studio-58bi的设置。

我把它解压缩在我的主目录里。我也这样做了：

sdkmanager "platform-tools"
sdkmanager "build-tools;28.0.3"
sdkmanger "platforms;android-29"

我的目录看起来类似于：

android-sdk/
           build-tools/
           cmdline-tools/
           emulator/
           licenses/
           patcher/
           platforms/
           platform-tools/
           tools/

此外，我将内容从cmdline-tools移到cmdline-tools/tools，下面是答案：https://stackoverflow.com/a/65262939/13725696。

我做了flutter config --android-sdk /home/[username]/android-sdk/，但是我还是在运行flutter doctor时得到了这个

[✓] Flutter (Channel stable, 2.2.3, on Linux, locale en_IN)
[!] Android toolchain - develop for Android devices (Android SDK version 28.0.3)
    ✗ Android license status unknown.
      Run `flutter doctor --android-licenses` to accept the SDK licenses.
      See https://flutter.dev/docs/get-started/install/linux#android-setup for
      more details.
[✗] Chrome - develop for the web (Cannot find Chrome executable at
    google-chrome)
    ! Cannot find Chrome. Try setting CHROME_EXECUTABLE to a Chrome executable.

编辑：我刚刚注意到：

    ✗ Android license status unknown.
      Run `flutter doctor --android-licenses` to accept the SDK licenses.

我做了flutter doctor --add-licenses，但我收到了这个：

必须添加这样的环境变量：

export ANDROID_SDK_ROOT=/home/[username]/android-sdk/
export PATH=$PATH:$ANDROID_SDK_ROOT/cmdline-tools/tools/bin
export JAVA_HOME=/usr/lib/jvm/java-8-openjdk-amd64/
export PATH=$PATH:$JAVA_HOME/bin

返回到主目录中的~/.bash_profile并重新启动。
