Try each step separately:
- Restart Eclipse
- Clean project and rebuild
- Create a new project and try it if the problem persists, if no move copy project to other folder, delete project from workspace , create new project same name and copy java, xml etc. files to new project
- Close Eclipse, backup folder c:\Users\myName\workspace\.metadata and delete it. Restart Eclipse try again import project to workspace
- Re-installing the Android Developer Tools
- Re-installing Eclipse - rename old folder with Android to Android_old, create new folder C:\Program Files\Android and copy new Eclipse with sdk into new folder
- Created a new project importing from the file system
- Created a new project from subversion
