Android development with Flash Platform

First of all I’d like to say thank you to JUG Padova that give me opportunity to talk about Flash Platform in own Java User Group.
Saturday morning I got a talk about Android development with Flash Platform in a school in Padova.
There were 40/50 people more or less, students, Flash Platform devs and Java devs, so I’m glad about the final result.

I talked about my experience on working with Flash Platform on Android, suggested some tips & tricks to improve own applications made with AIR or web site for Flash Player on Android and finally I reported latest news from Flash on the Beach general session.

Adobe has just released Adobe AIR for Android so from last weekend you can download it and start to develop your own Flash Platform contents for Android devices.

You can download my presentation slides with some samples directly here, for now slides are in Italian but if someone is interesting in an English translation feel free to add a comment here.

Flash Platform on Android

Sorry if I don’t post anything until now but I study a lot during last months and finally I’ve time to write a new post about Flash Platform on Android.

I’m glad to talk about this argument because after Flash Lite experience I was not so excited to work with these technologies on mobile, but finally I can say that we can forget Flash Lite experience in this new way to think mobile.
First of all I’d like to share with you a thought about Adobe mobile direction.
Adobe is releasing 3 cool mobile technologies Flash, Flex and obviously AIR; the most interesting for me is Flex 4.1 (codename HERO) that allow to create contents for RIAs, Dekstop Apps, Mobile RIAs and Mobile Apps.
In fact with HERO, Adobe gives us opportunity to develop better and faster with the same framework! Yes, you read well, 1 framework for everything!
They add some cool components dedicated for mobile development like ActionBar or ViewNavigator. It’s really impressive!
If you have an Android FroYo device, try to download some .apk file made with Flex on Coenraets blog.

I think Adobe is going to the right direction and new technologies that will be released in next months give us a new opportunity to bring our contents and deliver them to mobile! So THANK YOU ADOBE!

After these considerations, I’d like to talk about few experiments that I tried during last weeks.
Flash Platform on Android works very well, cool performance and with a good coding you can create great stuff.
I’m working on a mobile library with some useful components like grid, list, image and so on; I think that work with Flash Platform on mobile is so easy if you have an idea on how to work for mobile.
Obviously, if you are a Flash developer you are not a Flash mobile developer automatically! But you can become a mobile developer in few easy steps:

1. Optimize your code: remember to remove all listeners, put variables to null, using object pooling instead of create and destroy variables, use design patterns and so on.
2. System.gc() finally works! On Flash Player 10.1 if you run this command it works very well and save lots of memory for your porjects!
3. Don’t insert tons of stuff on your screen: when you design UI of your application remember that you have a small screen so remember to work with 14px fonts (minimum size), big hit button area (50px minimum), optimized images, avoid vector strokes.
Remember also to test if an asset is better in pixels instead of vectors or viceversa, because sometimes trying on device is the best way to find an answer!
4. Test on device anytime you add a consistent feature.
Don’t test your application only when you finish it, but test anytime you add a new feature because what you see on your computer could not be the same on your Android device!

Those are only few suggestions to start to work with Flash Platform on Android; on Amazon I saw that many people will release some cool books about Flash Platform development on mobile device so please take a look!

Finally, I give you a couple of videos about a runtime image manipulation on Android with Convolution filter made in less then 50 lines of code and a new component that I develop for our library called Skeleton component that simulate navigation of iPad Wired app but made for Android with Flash Platform.
I’m finishing it but for now I’m glad for final result; it’s totally XML driven and you can add swf, videos or images, send data to swf files and so on.
A cool test that I made is to port it on an AIR app for desktop and without changing a line of code I have the same result!
So if you plan your development well you can have one core and different deploy, thank you again Adobe!
Now I want to try it on an Android tablet and then I’ll post some results about that.
For now I can say that Flash on Android will revolutionize Android mobile development experience and if Adobe goes in this direction I can say that they will revolutionize mobile developer life (not for all, isn’t it Steve?!).
