Android: How to set Android drawable resource as unity scene background?

Unity Engine

In my Android app I have a unity scene that I have embedded in a view. I want to be able to change the background of this scene dynamically using Android drawable resource files. So what I mean is say I have some images in drawable directory. In Android, we access these drawables as, R.drawable.image_name etc

I want to set these drawables as Unity scene background. Is this possible? I have been communicating between unity and Java code via the

 UnityPlayer.UnitySendMessage("GameObject", "Functionname", "Param");

I can also import an image from the gallery to the android scene. But I can’t find anything to achieve the above requirement. Any help would be appreciated. Thanks!!
