SESSION OVERVIEW
WHAT IS A NATIVE EXTENSION?
• Extend the features of the AIR runtime !
• For TV, Mobile, Desktop
WHAT IS A NATIVE EXTENSION?
Flex
ActionScript
AIR
OS
extension
AS3
DLL
AS3
JAR...
WHAT IS A NATIVE EXTENSION?
library.swf
ext.dll
library.swf
ext.jar...
extension.xml
catalog.xmllibrary.swf
ANE FILE STRUCTURE
ANE FILE STRUCTURE
REGULAR SWC FILE
ANE FILE STRUCTURE
ANE FILE
WHY?
• access native platform specific code libraries
• Re-use legacy native code
• Increase performance (native performance / threading)
WRITING AN EXTENSION
• ActionScript: ExtensionContext class
•Native:
• C entry point on Windows, OSX, iOS (& Android)
• Java entry point on Android
WRITING AN EXTENSION
adt ane file
1. Create ExtensionContext object
2. Look up link with native code in XML
3. Link the context initializer
4. Link the native functions in the context initializer
5. Call a method in native code
context initializer
context finalizer
function calls & events
extension initializer
extension finalizer
Demo Hello World
• Construct new AS3 Objects
• Get AS3 Object Type
• Get / Set properties of AS3 Objects
• Call AS3 Object methods
WORKING WITH AS OBJECTS
WORKING WITH AS OBJECTSSIMPLE DATA TYPES
WORKING WITH AS OBJECTSAS CLASS INSTANCES
WORKING WITH AS OBJECTSEXAMPLE:
ARRAY / VECTOR METHODS
BYTEARRAY / BITMAPDATA
acquire
release
memory access No other API methods are allowed here
BYTEARRAY / BITMAPDATA
BYTEARRAY / BITMAPDATA
EXAMPLE:
Demo ByteArray Access
THREADING• Is allowed in the native extension :-)
•NO FRE API calls allowed outside the main thread
• except for : FREDispatchStatusEventAsync
THREADING
Demo Threading
WHAT ABOUT ANDROID ?
• C API for Windows, OSX & iOS
• Java Wrapper for Android:
• com.adobe.fre.FREExtension
• com.adobe.fre.FREContext
• com.adobe.fre.FREFunction
create instance of...
returns collection of...

PACKAGING AN ANE
1.Compile SWC of your AS3 code
2.Unzip SWC file, get library.swf file
3.Put swc, library.swf, extension.xml & native builds (dll, ...) in one directory
4.Run adt command
