check also the length of the string that is returned:

if (text == null || text.length() == 0)

if you also want to check whether the string consists only of whitespace, you will have to use either regular expression or iterate over the string. e.g.:

if (text == null || text.matches("\s*"))

ups, change it to:

if (text == null || text.matches("\\s*"))
