我正在尝试在 Android 开发者网站 (here) 上做 Android 教程。我在站点上安装了 Eclpise/Android SDK 包，但是当我尝试运行自动生成的代码时，它应该只显示“Hello World”，我得到一个 java.lang.NoClassDefFoundError。我自己还没有编写任何代码。

这是错误的logcat日志:

这是我的第一个问题，所以请让我知道是否还有其他我应该包括的内容。

Answer 1

当您的代码依赖于一个类文件并且它在编译时存在但在运行时找不到时会导致这种情况。寻找构建时间和运行时类路径的差异。

while u r running ur code android.support.v7.appcompat.R$styleable class is missing. find the jar which contain this class... add to class path then run.
