我试图重组，使现有的应用程序，除了在派生活动几覆盖，能够方法，所有code将驻留在库中。这仍然doesn't出于某种原因的工作，但在试图解决此过程中，我发现了令我失望，有两个的apk安装文件，而不是一个（当我运行调试会话从日食）：

I am trying to restructure an existing app so that, except for a few override-able methods in a derived activity, all code will reside in a library. This still doesn't work for some reason, but in the process of attempting to troubleshoot this, I discovered much to my dismay that there are two .apk files installed, not one (when I run a debug session from eclipse):

在第一个（和更大的文件）是 具有原始的库名称。 第二（仅在大小20KB）是 其派生的应用程序的名称。 The first (and larger file) is having the original library name. The second (only 20KB in size) is having the derived application name.

这是为什么，我在哪里可以了解更多关于此？

Why is that and where can I learn more about this?

莫非是解释ClassNotFoundException问题我有？

推荐答案

我发现自己的答案。事实证明，我在两个项目的属性2关键设置，设置不正确：

I found the answer myself. It turns out that I had 2 critical settings in the Properties of both projects not set correctly:

在库项目，是图书馆 未被选中的某些原因。一世 可以发誓，我查了一下，但 知道如何异想天开了Android 在开发环境 Eclipse可以的话，我怀疑它 在未选中的Eclipse（或ADT 插件），因为一些小故障的结果。 在应用程序项目，我 忘了加我的库项目 作为通过添加一个参考... 按钮。 （我多么愚蠢的可能呢？） In the library project, "Is Library" was not checked for some reason. I could swear that I checked it, but knowing how whimsical the Android development environment under Eclipse can be, I suspect that it was unchecked by Eclipse (or the ADT plugin) as a result of some glitch. In the application project, I neglected to add my library project as a reference via the Add... button. (how dumb could I be?)

希望这可能是有用的其他新手的到来。

Hoping this can be useful for other newbies to come.
