Since API 19 (KitKat) is still very popular, it is a good choice to support this release. However, it does not support many features, such as backgroundTint and ImageTint. This puts me in many compatibility issues and design choices.
I have several icons to load on a screen and I'm currently using setImageTintList to make the app dynamic.
"faces" and "bucks" should change color according to the element in a recyclerView. What is the best way to support this function on systems with API < 21 '
