问题描述

Eclipse 在工程A中调用B的文件出错

我工程A想调用工程B的文件，我是如下配置的：A工程右键->configure build path ->projects选择添加B工程。然后我直接在A中调用工程B的类（是在一个按钮中调用的）。项目没有报错，编译也可以过，可以当我APP安装后，点击这个调用了B类的按钮就会出错。错误如下

其中找不到的文件是我工程B中的文件。

解决方案

Eclipse js文件保存出错
----------------------

解决方案二：

你需要把B中要用到的类编译后生成jar库导入到A中，然后安装就没有问题了

解决方案三：

因为你是用的B工程中的类，所以你在安装的时候需要将B中class也打包到安装文件中，常用的就是引入B的jar包，不是太懂APP的东西。
