-Images, layout descriptions, binary blobs and string dictionaries can be included 
-in your application as resource files.  Various Android APIs are designed to 
-operate on the resource IDs instead of dealing with images, strings or binary blobs 
-directly.
-
-For example, a sample Android app that contains a user interface layout (main.xml),
-an internationalization string table (strings.xml) and some icons (drawable-XXX/icon.png) 
-would keep its resources in the "Resources" directory of the application:
-
-Resources/
-    drawable/
-        icon.png
-
-    layout/
-        main.xml
-
-    values/
-        strings.xml
-
-In order to get the build system to recognize Android resources, set the build action to
-"AndroidResource".  The native Android APIs do not operate directly with filenames, but 
-instead operate on resource IDs.  When you compile an Android application that uses resources, 
-the build system will package the resources for distribution and generate a class called "Resource" 
-(this is an Android convention) that contains the tokens for each one of the resources 
-included. For example, for the above Resources layout, this is what the Resource class would expose:
-
-public class Resource {
-    public class Drawable {
-        public const int icon = 0x123;
-    }
-
-    public class Layout {
-        public const int main = 0x456;
-    }
-
-    public class Strings {
-        public const int first_string = 0xabc;
-        public const int second_string = 0xbcd;
-    }
-}
-
-You would then use Resource.Drawable.icon to reference the drawable/icon.png file, or 
-Resource.Layout.main to reference the layout/main.xml file, or Resource.Strings.first_string 
-to reference the first string in the dictionary file values/strings.xml.
