Open a project in Eclipse

I'm completely new to Eclipse/Java/Android programming, so this might sound like a dumb question, but I can't open the project I was working on last week... it's the "HelloWorld" project.

I'm very familiar with Visual开发者_运维知识库 Studio so I've been looking for something like a project file/solution or a way to open a directory in Eclipse, but I'm having no luck and am completely lost.

Any help is appreciated!

Can you try File->Import and then choose Existing Projects into Workspace and then select the directory with your HelloWorld project?

Looks like I had it checked not to show closed projects.

Eclipse will look into the .project file in your project directory and see the original project name, which may be the same as another project. This can happen if you build a new project using some old code.
