To add cross-platform image assets for your Uno Platform app, use the Assets folder
in the shared project instead. Assets in this folder are Android-only assets.

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 you 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");
