FAILURE: 在Flutter中出现异常，构建失败。

androiddartflutter

我突然遇到了一个关于我的Flutter应用程序的问题。出现了一个错误，我无法运行任何Flutter文件。每次尝试运行任何Flutter项目时，都会出现错误消息。

FAILURE: Build failed with an exception.

* What went wrong:
Could not resolve all files for configuration ':flutter_appavailability:androidApis'.
> Failed to transform file 'android.jar' to match attributes {artifactType=android-platform-attr} using transform PlatformAttrTransform
   > java.io.FileNotFoundException: /Users/wooyoung/Library/Android/sdk/platforms/android-27/android.jar (No such file or directory)

* Try:
Run with --stacktrace option to get the stack trace. Run with the -the-info or --debug option to get more log output. Run with --scan to get full insights.

* Get more help at https://help.gradle.org

BUILD FAILED in 3s
Gradle task assembleDebug failed with exit code 1
Exited (sigterm)

因此，我创建了一个新的Flutter应用程序来测试是否只是我的项目存在问题。但是它再次给我报错。

FAILURE: Build failed with an exception.

* What went wrong:
Execution failed for task ':app:processDebugResources'.

我该如何解决这个问题？
你能在iOS模拟器上运行它吗？ - Phuc Tran
没问题，在我的 iOS 模拟器上可以。 - Young

似乎您的Android sdk目录中缺少必要的Android 27 API。请前往~/library/android/sdk/tools/bin并运行sdkmanager --list检查是否安装了platform-tools和platforms;android-27。如果没有安装，则可以通过运行sdkmanager "platform-tools" "platforms;android-27"来安装它们。如果您有安装Android Studio，则也可以通过Android Studio的GUI安装它们。
非常感谢你的帮助。但是，即使我已经下载了API，它仍然无法正常工作。 - Young
请尝试运行sdkmanager“build-tools;27.0.3”后再试一次，好吗？ - monatis
在我的终端里？ - Young
是的，在您的终端中，并通过更改到相同的目录 cd ~/library/android/sdk/tools/bin - monatis

尝试运行此命令：

flutter pub cache repair

打开文件菜单 ---> 项目结构 ---> 项目设置 ---> 项目

检查您的项目 SDK

还要检查 >>> 项目结构 ---> 平台设置 ---> SDKs

提供相同的 SDK 并单击确定

尝试运行项目

你应该保留默认的启动画面，因为加载程序需要时间！
