Interface compatibility issues between different API versions

Question

I am working on an application that uses a navigation box (which I created from an Android Studio activity template) that uses fragmentsinternally. Navigation box nested in mine MainActivity. I also included a menu in the toolbar, which has two more options; Filter and settings (settings created from the AS template too). I ran into problems testing the application between API 19 and 24.

My LoginActivity uses the attribute drawableLeftalong with drawableTint(which, as I know, only works for API23 and higher). How can I get the drawableLeft icon to display in white in older versions?

, Toolbar . API 24 ( Nexus 5X), Toolbar , API 19, Toolbar , . , Material Design, API 23+ ( ), ?
