Could you pass no argument to saveFreOrSecondRunPromoDisplayed(), and have these
AboutVersionStrings variables within DataReductionPromoUtils ?

Done.

+                .getAboutVersionStrings();
+        DataReductionPromoUtils.saveFreOrSecondRunPromoDisplayed(
+                versionStrings.getApplicationVersion());
     }
 }
