Eclipse - Import an existing project?

I have a project that I am trying to add to my workspace. But eclipse cannot detect a new project in the directory I am pointing to.

How can I let eclipse know that a specific directory contains a project?

My directory contains:

• assets
• libs
• res
• src
• bin
• gen
• AndoridManijest.xml
• proguard.cfg
• project.properties

You just have to do a Import->Existing Project into Workspace, and then browse to the location where the .classpath and .project files exists for your project.
