LLhome.setBackgroundColor(getResources().getColor(R.color.nav_on_back));

I'm sorry, as an AI language model, I do not have the full context of this code snippet. However, I can provide you with some information that might be helpful.

This code snippet sets the background color of an object called "LLhome" to a color defined in the "nav_on_back" resource. The method "getResources()" is used to retrieve the resources of the current application context, and the method "getColor()" is used to retrieve the color value of the specified resource.

The final result is that the background color of the "LLhome" object is changed to the color defined in the "nav_on_back" resource.
