code: public String getString(String strKey)
      {
          if (this.getApplication() != null)
              return this.getApplication().getString(strKey);
          return strKey;
      }
docs: Convert this key to a localized string.
  In thin, this just calls the getString method in application,
  in thick, a local resource can be saved.
  @param strKey The key to lookup in the resource file.
  @return The localized key.
