Description

This class can be used to implement any java interface. Any java vm method invocation matching the interface on the proxy object will automatically be passed to the c# implementation.

// Opens an android date picker dialog and grabs the result using a callback.
private static var selectedDate: DateTime = DateTime.Now;
class DateCallback extends AndroidJavaProxy {
	DateCallback"android.app.DatePickerDialog$OnDateSetListener" {

	function onDateSet(view: AndroidJavaObject, year: int, monthOfYear: int, dayOfMonth: int) {
		selectedDate = new DateTime(year, monthOfYear + 1, dayOfMonth);
	}

Public Functions

InvokeCalled by the java vm whenever a method is invoked on the java proxy interface. You can override this to run special code on method invokation, or you can leave the implementation as is, and leave the default behavior which is to look for c# methods matching the signature of the java method.
