更新应用程序兼容性-V7到最新版本，获得NoClassDefFound为AppCompatDelegateImplV23 [英] Updated appcompat-v7 to the newest version, get NoClassDefFound for AppCompatDelegateImplV23

问题描述

我读了CommonsWare博客，这是一个聪明的主意来更新应用程序兼容性-V7到前滚了最新版本的Andr​​oid出来的6.0，所以我只是一往直前，并试图做到这一点与我的Eclipse项目。更新库后（我只是删除了previous版本，并增加了新的资源），我（previously ActionBarActivity）AppCompatActivity不启动（应用程序崩溃）。这是LogCat中的内容：

I read on the CommonsWare blog that it's a smart idea to update appcompat-v7 to the newest version before the roll out of Android 6.0 so I just went ahead and tried to do that with my project in Eclipse. After updating the library (I simply removed the previous version and added the new one with resources), my (previously ActionBarActivity) AppCompatActivity does not start (the app crashes). This is the LogCat content:

我一直在试图解决这一问题了几个小时，但没有什么工作！我清洗，再清洗，去除库，重新添加，检查.jar文件所包含的类文件，果然有一个AppCompatDelegateImplV23有没有什么等等。

I've been trying to fix this for hours but nothing works! I cleaned, re-cleaned, removed the library, re-added, checked the .jar files for the contained class files and sure enough there's an AppCompatDelegateImplV23 there etc. Nothing.

任何想法？

推荐答案

我有完全相同的错误，并用以下解决方案来翻过：

I had exactly same error and came accross with following solution:

1. 与开发项目闭上你的实际工作区

1. Close your actual workspace with your DEVELOPMENT project

创建新的工作区

固定
