Beefing Up AIR - FITC AMS 2012
- 1. BEEFING UP AIR Native extensions in AIR 3.0
- 2. @WOUTER • Wouter Verweirder • blog.aboutme.be • Lecturer @ HOWEST • Partner @ Happy Banana • AS3NUI / AIRKinect
- 4. SESSION OVERVIEW 1. What is a native extension 2. Build a native extension 1. Hello World 2. Working with AS Objects 3. Threading / Communication 4. What about Android 3. Use a native extension 4. AIRKinect extension 5. Q & (hopefully) A
- 5. WHAT IS A NATIVE EXTENSION? • Extend the features of the AIR runtime ! • For TV, Mobile, Desktop
- 6. WHAT IS A NATIVE EXTENSION?
- 7. WHAT IS A NATIVE EXTENSION? Flex ActionScript extension AIR AS3 AS3 ... DLL JAR OS
- 8. ANE FILE STRUCTURE library.swf catalog.xml extension.xml library.swf library.swf ... ext.dll ext.jar
- 9. ANE FILE STRUCTURE REGULAR SWC FILE
- 10. ANE FILE STRUCTURE ANE FILE
- 11. WHY? • access native platform specific code libraries • Re-use legacy native code • Increase performance (native performance / threading)
- 12. WRITING AN EXTENSION • ActionScript: ExtensionContext class • Native: •C entry point on Windows, OSX, iOS (& Android) • Java entry point on Android
- 13. WRITING AN EXTENSION adt ane file
- 14. 1. Create ExtensionContext object 2. Look up link with native code in XML
- 15. 3. Link the context initializer 4. Link the native functions in the context initializer
- 16. 5. Call a method in native code
- 17. extension initializer context initializer function calls & events context finalizer extension finalizer
- 18. Demo Hello World
- 19. WORKING WITH AS OBJECTS • Construct new AS3 Objects • Get AS3 Object Type • Get / Set properties of AS3 Objects • Call AS3 Object methods
- 20. WORKING WITH AS OBJECTS SIMPLE DATA TYPES
- 21. WORKING WITH AS OBJECTS AS CLASS INSTANCES
- 22. WORKING WITH AS OBJECTS EXAMPLE:
- 23. ARRAY / VECTOR METHODS
- 24. BYTEARRAY / BITMAPDATA acquire memory access No other API methods are allowed here release
- 28. THREADING • Is allowed in the native extension :-) • NO FRE API calls allowed outside the main thread • except for: FREDispatchStatusEventAsync
- 29. THREADING
- 30. Demo Threading
- 31. WHAT ABOUT ANDROID ? • C API for Windows, OSX & iOS • Java Wrapper for Android: • com.adobe.fre.FREExtension create instance of... • com.adobe.fre.FREContext returns collection of... • com.adobe.fre.FREFunction
- 32. WHAT ABOUT ANDROID ? EXAMPLE:
- 33. WHAT ABOUT ANDROID ? EXAMPLE:
- 34. WHAT ABOUT ANDROID ? EXAMPLE:
- 35. Demo Mobile UDP extension
- 36. PACKAGING AN ANE library.swf catalog.xml extension.xml library.swf library.swf ... ext.dll ext.jar
- 37. 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
- 38. PACKAGING AN ANE adt -package -storetype pkcs12 -storepass p@ssw0rd -keystore key.p12 -tsa none - target ane HelloWorldExtension.ane extension.xml -swc helloworldas.swc - platform MacOS-x86 library.swf HelloWorld.framework -platform Windows- x86 library.swf HelloWorld.dll http://help.adobe.com/en_US/air/build/ WS789ea67d3e73a8b22388411123785d839c-8000.html
- 39. BUILDING APPS WITH ANE’S

- 42. AIRKINECT • Native extension to use the Kinect in your AIR apps • Current version: 1.7.1 • Full skeleton Data • Camera Streams: RGB & Depth • Point Cloud info

- 47. AIRKINECT 2.0 • Simplified API • New features: • Skeleton Joint Rotations • User center-of-mass • Point Cloud Regions • IR Camera Stream
- 48. Time for some Kinect coding!
- 49. Questions (and hopefully some answers...)
