Any raw assets you want to be deployed with your application can be placed in
2+
this directory (and child directories) and given a Build Action of "AndroidAsset".
3+
4+
These files will be deployed with you package and will be accessible using Android's
5+
AssetManager, like this:
6+
7+
public class ReadAsset : Activity
8+
{
9+
protected override void OnCreate (Bundle bundle)
10+
{
11+
base.OnCreate (bundle);
12+
13+
InputStream input = Assets.Open ("my_asset.txt");
14+
}
15+
}
16+
17+
Additionally, some Android functions will automatically load asset files:
18+
19+
Typeface tf = Typeface.CreateFromAsset (Context.Assets, "fonts/samplefont.ttf");

Images, layout descriptions, binary blobs and string dictionaries can be included
2+
in your application as resource files. Various Android APIs are designed to
3+
operate on the resource IDs instead of dealing with images, strings or binary blobs
4+
directly.
5+
6+
For example, a sample Android app that contains a user interface layout (main.axml),
7+
an internationalization string table (strings.xml) and some icons (drawable-XXX/icon.png)
8+
would keep its resources in the "Resources" directory of the application:
9+
10+
Resources/
11+
drawable/
12+
icon.png
13+
14+
layout/
15+
main.axml
16+
17+
values/
18+
strings.xml
19+
20+
In order to get the build system to recognize Android resources, set the build action to
21+
"AndroidResource". The native Android APIs do not operate directly with filenames, but
22+
instead operate on resource IDs. When you compile an Android application that uses resources,
23+
the build system will package the resources for distribution and generate a class called "R"
24+
(this is an Android convention) that contains the tokens for each one of the resources
25+
included. For example, for the above Resources layout, this is what the R class would expose:
26+
27+
public class R {
28+
public class drawable {
29+
public const int icon = 0x123;
30+
}
31+
32+
public class layout {
33+
public const int main = 0x456;
34+
}
35+
36+
public class strings {
37+
public const int first_string = 0xabc;
38+
public const int second_string = 0xbcd;
39+
}
40+
}
41+
42+
You would then use R.drawable.icon to reference the drawable/icon.png file, or R.layout.main
43+
to reference the layout/main.axml file, or R.strings.first_string to reference the first
44+
string in the dictionary file values/strings.xml.
