at …Run Code Online (Sandbox Code Playgroud) 我有一个在Eclipse IDE中运行的android项目.让我们说这是'ABC项目'.我的一些搭档已经制作了这个项目的副本数量,所以项目文件可以在桌面,C://,D://甚至在eclipse工作空间中看到.现在我不知道我正在运行哪个位置的项目,因为他们已经使用这些副本删除并导入项目文件夹到eclipse,他们不记得他们是否选择了"复制到工作区"选项.怎么能我得到这个位置?我试图右键单击该项目,看到任何选项,但没有.使用java代码(getAbsolutePath())手动找到它将返回没有好处,它将返回手机中的路径.
