Any raw assets you want to be deployed with your application can be placed in |
||||||
|
this directory (and child directories) and given a Build Action of "AndroidAsset". |
||||||
|
|
||||||
|
These files will be deployed with your package and will be accessible using Android's |
||||||
|
AssetManager, like this: |
||||||
|
|
||||||
|
public class ReadAsset : Activity |
||||||
|
{ |
||||||
|
protected override void OnCreate (Bundle bundle) |
||||||
|
{ |
||||||
|
base.OnCreate (bundle); |
||||||
|
|
||||||
|
InputStream input = Assets.Open ("my_asset.txt"); |
||||||
|
} |
||||||
|
} |
||||||
|
|
||||||
|
Additionally, some Android functions will automatically load asset files: |
||||||
|
|
||||||
|
Typeface tf = Typeface.CreateFromAsset (Context.Assets, "fonts/samplefont.ttf"); |

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-hdpi/ |
||||||
|
icon.png |
||||||
|
|
||||||
|
drawable-ldpi/ |
||||||
|
icon.png |
||||||
|
|
||||||
|
drawable-mdpi/ |
||||||
|
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" 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 R.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. |
