I know this is really old, but here's how I did it using ant within eclipse:

build.xml in project root

    
        This ant script updates strings.xml application_build_date to the current date
    

    
    

    
        
        
    

    

        

    

Then add an application_build_date string to your strings.xml

    your app name
    20140101
    ...

Ensure the ant script is executed as a pre-build activity and you will always have a valid build date available to you within R.string.application_build_date.
