Additions allow you to add arbitrary C# to the generated classes
before they are compiled. This can be helpful for providing convenience
methods or adding pure C# classes.
== Adding Methods to Generated Classes ==
Let's say the library being bound has a Rectangle class with a constructor
that takes an x and y position, and a width and length size. It will look like
this:
public partial class Rectangle
{
public Rectangle (int x, int y, int width, int height)
{
// JNI bindings
}
}
Imagine we want to add a constructor to this class that takes a Point and
Size structure instead of 4 ints. We can add a new file called Rectangle.cs
with a partial class containing our new method:
public partial class Rectangle
{
public Rectangle (Point location, Size size) :
this (location.X, location.Y, size.Width, size.Height)
{
}
}
At compile time, the additions class will be added to the generated class
and the final assembly will a Rectangle class with both constructors.
== Adding C# Classes ==
Another thing that can be done is adding fully C# managed classes to the
generated library. In the above example, let's assume that there isn't a
Point class available in Java or our library. The one we create doesn't need
to interact with Java, so we'll create it like a normal class in C#.
By adding a Point.cs file with this class, it will end up in the binding library:
public class Point
{
public int X { get; set; }
public int Y { get; set; }
}

This directory is for Android .jars.
There are 2 types of jars that are supported:
== Input Jar ==
This is the jar that bindings should be generated for.
For example, if you were binding the Google Maps library, this would
be Google's "maps.jar".
Set the build action for these jars in the properties page to "InputJar".
== Reference Jars ==
These are jars that are referenced by the input jar. C# bindings will
not be created for these jars. These jars will be used to resolve
types used by the input jar.
NOTE: Do not add "android.jar" as a reference jar. It will be added automatically
based on the Target Framework selected.
Set the build action for these jars in the properties page to "ReferenceJar".
