的NoClassDefFoundError与新的Eclipse包

Question

我对他们接收到错误客户告知。在报告中，他们提交的是时间可持续未来与NoClassDefFoundError错误。看来我的其他客户都没有遇到这个问题。我没有在我的Motorola Droid Maxx上运行该应用程序的问题。客户正在根植Droid Bionic上运行该应用程序。在2.3版本中，我的版本一切正常，但是当我将它更新到2.4时，出现了这个问题。我也用新的替换了我的电脑，现在我正在运行Windows 8并安装了adt软件包。我改变> -90到> -85时，对有问题的文件做的唯一更改。以下是代码...我还在代码下面包含了错误报告。这只发生在手机上。

Answer 1

这与SDK工具的R21版本的通病。进入你的项目设置，然后进入Java Build Path。如果展开“Android的相关性”，你会看到，现在有一些你的.jar文件从你的libs文件夹重复。

取下顶层只留下那些在Android依赖文件夹的任何重复。然后做一个干净的项目，你应该很好再次去。
