How to write common step def for Android and iOS when the locators are different for both and value is passed from feature file

Question

I have a situation where

For example: Android locator is having account number 6 1 8 8 iOS is having account number as 6188

All my steps are same only the account number locator is different which I am passing it from a feature file. How can I write a code which works for both. This is because I am not hardcoding the locator in my locators java file. Am passing it from feature file.
