问题描述
现在我已经试过这2小时，我不似乎得到它的工作。我想建立一个框架，我的应用程序，在另一个项目。首先我只是试图从其他项目中达到一类。在code编译，但无法在运行时，在那里我实例化一个对象从一个类从框架就行了。
I've tried this for 2 hours now and I dont seem to get it to work. I want to build a framework for my application, in another project. First of I'm just trying to reach a class from that other project. The code compiles but fails at runtime, at the line where i instantiate an object from a class from the framework.

我知道有很多关于这个话题，但我已经搜索了几个小时，不解决这个问题的文章。大部分的主题是如何引用到另一个项目。但因为我的code正在编制应当参考？
I know there is a lot on this topic, but I've have searched for hours without any posts solving this problem. Most of the topics are how to reference to another project. But since my code is compiling it should be referenced?
和没有这两个项目必须是Android的项目？如果框架项目是一个库？感谢您的帮助！
And does both projects needs to be Android projects? Should the framework project be a library? Thanks for any help!
推荐答案
如果库项目是一个Android项目，你需要从的项目属性，然后通过的同一个地方但使用它的项目。
不要忘了，有一些规则，当您使用库项目。看到我的帖子这里获取更多信息。
if the library project is an android project , you need to make it a library one by choosing it from the project properties , and then to reference it via the same place but on the project that uses it. don't forget that there are some rules when you use a library project . see my post here for more information.
如果库项目是Java的，它正是因为使用其他Java项目。
if the library project is java , its exactly as using other java projects.
