Dropbox Android API sample project won't run

I've download the Dropbox Android API, unpacked the sample project and opened it in Eclipse. However it has trouble with importing the API:

import com.dropbox.client.DropboxAPI;
import com.dropbox.client.DropboxAPI.Config;

it can't find it. I have dropbox-client-1.0-SNAPSHOT.jar in the lib folder of my proj开发者_如何学JAVAect, which is where I assume these classes are, but it can't access them. What do I need to do to get up and running?

Ok, I've fixed this, I needed to add the jars to the Java Build Path in the Project's Properties.
