What is the hex code for the default white background that is given to layouts when you create a new project?

This answer shows you to get the default background color.
To summarize, just do something like this
TypedValue a = new TypedValue();
getTheme().resolveAttribute(android.R.attr.windowBackground, a, true);
int color = a.data;
Then color will contain the value. This might be useful because the background might be different across different platforms (as the javadoc mentions, you can only count on the background being light).
