Answer 1

Read this :

If you look at the source code for DrawableCompat you will see that for any version < support library 21 the method does nothing.

The idea of DrawableCompat seems to be simply not crashing on old versions, rather than actually providing that functionality.

UseFul Tips :

With support library 22.1 you can use DrawableCompat to tint drawables.

DrawableCompat.wrap(Drawable) and setTint(), setTintList(), and setTintMode() will just work: no need to create and maintain separate drawables only to support multiple colors!

Answer 2
