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.axml),
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.axml
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 "R"
(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 R class would expose:
public class R {
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 R.drawable.icon to reference the drawable/icon.png file, or R.layout.main
to reference the layout/main.axml file, or R.strings.first_string to reference the first
string in the dictionary file values/strings.xml.

<!--
This file contains Runtime Directives, specifications about types your application accesses
through reflection and other dynamic code patterns. Runtime Directives are used to control the
.NET Native optimizer and ensure that it does not remove code accessed by your library. If your
library does not do any reflection, then you generally do not need to edit this file. However,
if your library reflects over types, especially types passed to it or derived from its types,
then you should write Runtime Directives.
The most common use of reflection in libraries is to discover information about types passed
to the library. Runtime Directives have three ways to express requirements on types passed to
your library.
1. Parameter, GenericParameter, TypeParameter, TypeEnumerableParameter
Use these directives to reflect over types passed as a parameter.
2. SubTypes
Use a SubTypes directive to reflect over types derived from another type.
3. AttributeImplies
Use an AttributeImplies directive to indicate that your library needs to reflect over
types or methods decorated with an attribute.
For more information on writing Runtime Directives for libraries, please visit
http://go.microsoft.com/fwlink/?LinkID=391919
