Question

我的Flutter应用突然出现问题。由于某种原因，我无法运行任何flutter文件。每次我尝试运行任何flutter项目时，都会不断显示错误消息。

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 --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，我制作了一个新的flutter应用程序来测试它是否只是我的项目中的问题。但这又给了我一个错误。

FAILURE: Build failed with an exception.

* What went wrong:
Execution failed for task ':app:processDebugResources'.
> Android resource linking failed

我该如何解决？

Answer 1

Android sdk目录中似乎缺少必要的Android 27 API。请转到~/library/android/sdk/tools/bin并运行sdkmanager --list，以检查是否已安装platform-tools和platforms;android-27。如果没有，那么您可以通过运行sdkmanager "platform-tools" "platforms;android-27"

来安装它们

如果您拥有Android Studio，则也可以通过Android Studio的GUI安装它们。

Answer 2

您应该离开默认的初始屏幕，因为加载程序需要时间！

<?xml version="1.0" encoding="utf-8"?>
<!-- Modify this file to customize your launch splash screen -->
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
   <item android:drawable="@android:color/black"/>

   <!-- You can insert your own image assets here -->
<!--     <item>
       <bitmap
           android:gravity="center"
           android:src="@mipmap/launch_image"/>
   </item> -->
</layer-list>

Answer 3

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并点击确定

尝试运行项目

Answer 4

尝试运行此命令：

flutter pub cache repair
