NoClassDefFoundError ResourceFolderType [英] NoClassDefFoundError ResourceFolderType

问题描述

当我尝试构建我的应用程序时出现此错误:

  Error:Module'MyApp'生产:java.lang.NoClassDefFoundError:com/android/resources/ResourceFolderType 

我使用Android Studio 4.1，Flutter和Dart.我进行了搜索，感觉是整个互联网，但没有找到解决方案.SO上有一些帖子描述了NoClassDefFoundError和ClassNotFoundException之间的区别(

I get this error when I try to build my app:

Error:Module 'MyApp' production: java.lang.NoClassDefFoundError: com/android/resources/ResourceFolderType

I use Android Studio 4.1, flutter and dart. I've searched, what feels to be the entire internet, but found no solutions. There are some posts here on SO that describes the difference between NoClassDefFoundErrorand ClassNotFoundException (IE), but no hints on how to resolve this. Or more likely not explained in a sufficient dumbed down manner so I can understand it...

It seems to me that ResourceFolderType is suppose to exsits somewhere, URL, but that doesn't help me either.

My futter doctor looks like this:

Doctor summary (to see all details, run flutter doctor -v):

[√] Chrome - develop for the web
[√] Android Studio (version 4.1.0)

• No issues found!

Any hints or pointers on what to do would be very much appreciated. Even just a link to the one site on the web I have not visited yet that describes a solution...

解决方案

I had the same issue. In my case, the solution was to choose the right way to build *.apk. Instead of choosing Build > Generate Single Bundle / APK ... I chose Build > Flutter > Build APK. This menu item is shown only when a window of any open project file is active.
