This is how I did it with Android 3.3.

Check in any unsaved changes to your repository.

• Right click your App's module -> Refactor -> Remove Unused Resources -> Preview
• In the Refactoring Preview, collapse both the views ('Items to be deleted' & 'Unused Resource Declarations')
• Right click 'Items to be deleted' -> Exclude
• Right click 'Unused Resource Declarations' -> Exclude
• Now expand 'Unused Resource Declarations' and under that locate your app specific strings.xml (there would be multiple strings.xmls)
• Right click that strings.xml -> Include
• Do Refactor! All unused strings from the xml file are deleted!

Note: Try building the project. If compilation fails, its most likely that these strings.xml is being referred from some layout/menu xmls, which themselves are unused. So those layout xmls can also be deleted manually!

Build and run. Test!
