Where are all the standard Android icon resources?

Question

I have just started writing my first ever Java/Android application, so forgive the total n00b question.

How do you access the the standard operating system icons suc

Answer 1

A lot of them can be found in android.R.drawable but not all are publicly accessible

Answer 2

For those of you in the Visual Studio/Xamarin Android camp, you can view and add the standard Material icons pretty easily using the following plugin:

I've used it a few times in my projects.
