【问题描述】：

我运行 flutter build apk --release 一切正常我运行调试 apk 并且它工作但我在运行发布 apk 时遇到了这个问题

Running Gradle task 'assembleRelease'...                          386,9s (!)

    The built failed likely due to AndroidX incompatibilities in a plugin. The tool is about to try using Jetfier to solve the incompatibility.
    Building plugin audioplayers...
    Running Gradle task 'assembleAarRelease'...                         6,2s
    
    
    FAILURE: Build failed with an exception.
    
    * What went wrong:
    A problem occurred configuring root project 'audioplayers'.
    > SDK location not found. Define location with sdk.dir in the local.properties file or with an ANDROID_HOME environment variable.
    
    * Try:
    Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output. Run with --scan to get full insights.
    
    * Get more help at https://help.gradle.org

    The plugin audioplayers could not be built due to the issue above.
    Process finished with exit code 1

尽管我的项目使用了AndroidX，因为错误提示我未使用它的包有问题，但在我删除所有包之前，问题总是伴随着另一个问题出现我需要一些帮助

【解决方案1】：

在准备要发布的 apk 时，您不需要运行 --release 命令。假设您已按照文档正确设置 build.gradle，只需运行此命令：(https://flutter.dev/docs/deployment/android)

flutter build apk

[编辑] 你能上传你看到的整个日志条目吗？除了确保增加日志的详细程度。所以在这种情况下：

flutter build apk -v

然后将其上传到线程。您正在使用的软件包与您当前的 android 版本（最低）不兼容。您在 gradle.build 文件中设置的最低 Android SDK 版本是多少？确保设置为所有软件包都支持的数字。取决于包装，但根据我的经验，21 足以涵盖全部范围。

【讨论】：

同样的问题
我将日志添加为答案，因为它有点大 sdk 版本从一开始就是 21 我已经删除了 4 个包，总是同样的问题我不能这样工作
写出问题：“SDK location not found。使用 local.properties 文件中的 sdk.dir 或 ANDROID_HOME 环境变量定义位置”
我怎么不明白
您需要在您的机器上配置Android SDK。您是在 Windows 还是 Mac OS 上工作？请参阅文档并确保在运行颤振编译之前先设置好机器：developer.android.com/studio/install
