Open letter to @Adobe and @Adobe Air: the hidden part…

I don’t know if you had already read the open letter that Gary wrote recently discussing about the arguable marketing choice made by Adobe on Adobe AIR but also previously about the Flash Platform in general, but I suggest you to start from there before read this post.

If you know me personally or you are following me in the social networks or reading this blog you should know that I’m a big fan of Flash Platform, in particular of Adobe AIR.
I’m very committed to deliver amazing and cutting edge projects made with this fantastic technology and I’m involved in the community to spread the word about AIR.
From a developer perspective I’m 110% with Gary and the community; an amazing technology like Adobe AIR with really a lots of success behind in terms of developers and companies that adopted this technology and in terms of numbers of apps in released during the past few years in different platform.
AIR, in my opinion, should have a better commitment from the company that create it (partially).
Obviously I agree also that there isn’t any competition between Actionscript 3 and HTML5 (read Javascript), what you can really do with HTML5 is what a flash developer could do 5 years ago more or less.
But you can’t approach a discussion like this talking only from a developer perspective, you and we should see it from different angles also.
What I’m asking you is to follow me until to the end of this post then you can send me an email and ask me if I became totally crazy or insult me with a comment, no worries :D

I usually goes to Adobe Max since 2006, first MAX organised by Adobe, and I remember quite clearly that few MAX ago during both keynotes nobody said anything related to new Flash Platform improvements or plan for the future of the platform.
At the beginning I was so hungry and I spent literally hours on the phone to talk with Adobe people because the 100% of my business was based on this technology and they can’t really think that HTML5 could be better that Flash Platform, in particular in 2011/2012 where the most coolest websites, RIAs and desktop applications were realised with Flash.
But have you ever tried to think from a different point of view this situation? Let’s assume for few minutes that we are inside the meeting room of the Adobe.
You have an amazing technology that millions of people is using to innovate and create the best software in the world but you are not earning what you expect from it, don’t you believe me? Take a look at this chart (ADBE):

ADBE stock 2011/2012

 

This is the graph of Adobe stock (ADBE) from January 2011 to December 2012, the value of the stock was for few months (close to October when usually Adobe Max takes place) lower than $28 and never greater of $35.
Great, obviously our white collars friends, aren’t so interested about which is the best technology in the market or how many people is using it; they care about numbers, how to increase the profit of the company and make happy the analyst to have a better position in the stocks market and with the shareholders.
These results weren’t so good for Adobe in fact, if you remember well, a lots of people started to leave the company, a lots of team was closed in USA or Europe to move the development side in India or in places where the developers are cheaper and Adobe started his commitment on the big new trend of new web technologies products like the Edge family for instance.
Everybody now knows very well the following story about the new products and how they are trying to improve the way to create websites and apps, and I guess the majority of us it’s not so happy about that.
But let’s take a look again to some numbers, the next graph will show you the Adobe stock value from 2012 to March 2014 basically in the period where Adobe left to push the Flash Platform and started to increase the investment on designers products:

ADBE stock 2012/2014

I think is quite explicit that the politic to start selling their products on Cloud (first big mover in the IT panorama), the decision to try to improve a new technology like HTML5 with new tools and so on, create around the Adobe what the management was looking for!
I agree with you that there are many ways to make money but from the metrics perspective they are going in the right direction and they did the right choices for now.
I’m not an economist and I can’t say if this strategy will pay in the long term but for sure in the short term they arrived where they wanted to be.

With this post I’m not trying to defend Adobe, but after many years where the Flash Platform is in this status I started to leave my angry mood and to interrogate myself on why they took this decision, honestly I can’t say if that it’s the only reason that drives Adobe in these big changes but excluding the technical side that’s the only way I can see this thing and now most part of their decision make finally sense.
All the comments I’ve read in the past and also in these days after the Gary’s letter to Adobe is completely true but often, as developers, we forget that it’s not just a design pattern or a performance optimisation that could save the world, the marketing and the market are the real drivers, in front of them also a big corporation like Adobe could defeated.

UPDATE FROM ADOBE

Photoshop, Edge Reflow and Edge Inspect: the new responsive workflow

Today I’d like to talk about something that is not strictly related to development process but that it’s very useful when you are running your company as freelance or entrepreneur or if you are team leader of a team.
One of the most important thing for me when you approach a new technology is not only understand if it could fit all your needs but also understand when you introduce in your team or company how to have the best result as soon as possible.
That’s why I keep always a lot of attention on how to create a flexible and elastic workflow that allow my team to create or modify client side solutions without waste our time.
In last years we rapidly see the grow of an hot topic, strictly related to HTML5 and Javascript, like Responsive Design, so the capability to create an interface that is viewable and usable on different devices (from smartphones to web browsers for instance).
Personally, if I didn’t find anything that help my team to be immediately very productive I usually avoid to introduce new softwares in the actual workflow, but this time we are in the middle of a big revolution where HTML5 and Javascript are the main protagonists.
During last Adobe MAX I saw a couple of interesting demo on Edge “family” and I was impressed on the capability of Edge Reflow and its interaction with Photoshop CC to create user interfaces for different devices in really few time, that’s why I was really waiting to test this feature and I’d like to share with you my first experiment.

Photoshop CC and Edge Reflow

I think a lot of designers create the UI for a project with Photoshop, last Monday (9th September) Adobe released an update of Photoshop CC and Edge Reflow, but we start with Photoshop because the news are really cool.
One of the most boring activity for a designer (or for me when I did it as freelance :D) is to cut all images and prepare assets in different folders for the developers.
Photoshop CC helps us introducing a new feature called Adobe Generator, a new way to automate this long and tedious phase, where the designer has only to follow some simple rules on how to nominate Photoshop levels and the software automatically export all the assets for us, ready to be delivered to the developers team!
For instance if you want to export a particular level as PNG you need only to nominate the level with a PNG extension (for example: “background.png”) and run the new Photoshop command Generate > Image Assets to have all our files ready to be added on the real project.

Photoshop Generate command

To know more about Adobe Generator and in particular to know how to set the name of each level I warmly suggest to take a look to Photoshop.com where there are all the information to do that.
Another option that we have (as you can see in the image above) is the capability to export the UI structure and the assets to Edge Reflow.
If you don’t know what is Edge Reflow I explain it in few words.
Edge Reflow is a tool useful to create responsive design layout and, from yesterday, completely integrated with Photoshop CC.
In fact now you can import in Edge Reflow your layout and you can start to customise it visually for any screen resolution your project will work.

Edge Reflow

The most interesting thing is that you can export from Photoshop an Edge Reflow project, or you can synchronise in real time the changes when the 2 softwares are open.
Then you can create your layout for different resolutions only copying and paste the code generate from Edge Reflow in your favorite code IDE; I mean copy and paste for now instead of import because probably (at 99%) you’ll have to improve or change it a little bit after paste but it’s really a good step forward for a software in preview like Edge Reflow.
With Edge Reflow you can create <div> adding box elements in your layout and you can show or hide elements present in different screen resolution simply with the options in the left side of the software interface.
Another very cool thing is the capability to work with your Typekit account (integrated in your Creative Cloud subscription) to download the fonts needed in the layout made with Photoshop.

Edge Reflow and Edge Inspect

Last but not least, Edge Reflow is integrated with another cool product of the Edge family called Inspect.
Edge Inspect is a simple application that you can add as plug-in in Chrome or you can download in your iOS or Android device from the relative store, and it allows you to test in real time all the changes you are doing in a website or more in general in HTML, JS or CSS file checking in real time the final result in one or more than one device simultaneously.
This is a capability that partially missed in the flash development workflow where the mobile test was a real pain (in particular the first releases of Adobe AIR on mobile), in this case with all those new technologies Adobe decides to evolve and improve this experience giving good tools to develop.

From a developer perspective

Personally I think that the integration of a technology like Node.JS in last Adobe softwares (Brackets, Adobe Generator, Edge Reflow and so on) is giving a real boost to them, and they are opening new horizons in the desktop application field, in particular I suggest to take a look to Node-Webkit, an open source project that allow you to work with HTML5, Javascript (Node.JS obviously) and WebGL to create desktop application for different platforms.
There are many other tools that could help to achieve the same goal like TideSDK for example, but I think Node-Webkit could be very interesting if the project will be well approach by the community.

Conclusions

Demo Photoshop and Edge Reflow

Finally the big players on the market are delivering tools that allow us to create engaging and amazing experience with HTML5 and Javascript like other technologies did in the past (Flash Platform in primis).
The combination of Photoshop CC, Adobe Generator, Edge Reflow and Edge Inspect give us a real flexible and integrated workflow where in few steps we can save a lot of hours spent on the code with great results.
Obviously those tools are new and in “preview” so they are not perfect but they are stable and useful enough at this point to be integrated in the actual daily workflow giving immediately importart results.
I really hope this is the first steps to give us the freedom to create instead became crazy to have layouts working in different browsers and devices.

Dart: elements iteration and CSS manipulation

In my exploration of Dart I’m trying to work in some easy examples that could help me to understand how to accomplish some tasks with this technology.
In this example I tried to understand better how iteration of elements works in Dart, how to create a layout with custom elements (more or less the same topic of a custom item renderer in Flex for example) and finally how to create some animations with CSS3 at runtime.

To accomplish those topics I decided to create a responsive image gallery that works on smartphone, tablet and web too.

Iteration

Dart gives few opportunities to iterate trough elements:

  • with Dart language (a classic for cycle)
  • with an HTML template
  • with elements composed by an HTML template and some dart code to cover the business logic of the final element

I jump directly to the second and third method, the first one is quite easy for any developer ;-)
In my sample I decide to use a simple HTML template, so basically you can define inside your html a tag <template/> that will allow you to repeat the HTML inside this tag associating it to a list for example, I give you a quick sample:

 <div id="imageCont" class="wrap">
      <template iterate="data in results">
        <div class="image">
          <img id="img_{{data[0]}}" class="faded" src={{data[1]}} width="320" height="240" on-click="onClick($event)" on-mouse-out="onOut($event)" on-mouse-over="onOver($event)" on-load="fadeIn($event)"/>
          <img id="zoom_{{data[0]}}" src="images/zoom.png" class="zoom"/>
          <h2><span>{{data[2]}}</span></h2>
         </div>
      </template>
    </div>

First of all take a look on how I can iterate this part of code; I add a simple iterate attribute associated to a list object (called results in my example) added in my dart file as a public variable.
The list could be a plain list or a list of objects, in this last case you can create multiple iteration item inside the template cycling trough your objects in the same way you have just seen.
I can substitute my data variable with any other name and I don’t need to define in my dart file, as you can see I can also define some variables inside the template getting values from my list object with this syntax: {{data[0]}} (or {{data["value"]}} it’s the same, depends how you have create the list object).
If you need, you can also made your source variables bindable and any time you’ll change the values of your list, also the view will change the number of elements or the values showed in the HTML page.

Finally when you need to create an iterable object with a complex business logic and you want to separate from the original HTML file you can do that creating a Web Components, but in this case I suggest you to take a look to the Dart language guide that explain very well how to achieve this topic.

Modifying CSS with Dart

Another interesting topic is how to change, add or remove css styles to my DOM objects.
In Dart is so easy like any other javascript library, so basically any DOM element in Dart has a property called “classes” with its associated method add and remove, so when you want to change your CSS class with another one, you have, if you have any classes already associated to the element, remove the old class and then add the new one:

var myDomObj = query("#idObject");
myDomObj.classes.remove("class-to-remove");
myDomObj.classes.add("class-to-add");

You can also style any single property directly with “style” property and set them directly in this easy way:

var myDomObj = query("#idObject");
myDomObj.style
             ..color = "0xFFF"
             ..fontSize = "15px";

As you can see working with CSS in Dart is relative simple, if you want to take a look to the whole project feel free to download it.

Another cool thing that is so useful when you work with mobile apps or websites is to test quickly and frequently your content on the devices, so with DartIDE (you can find it downloading Dart SDK) you can easily test your content trough a web server that starts any time you are testing your app into the browser.
It’s so interesting because you save a lot of time in this way!

I’m trying to figure out right now an hypothetical workflow to create web app, web sites or any other thing with Dart and HTML5.
I believe that use Dart in combination with Edge Reflow could be the best way to create responsive application for any kind of devices, but we have to wait until the release of Edge Reflow (17th June) to know if my supposition is true or not.
When it’ll be released and I’ve few time to invest, I’ll prepare another tutorial around this workflow.
In the meanwhile I hope you are enjoying those experiments with Dart and if you are interesting in any kind of topics on Dart feel free to suggest trough a comment in this post or sending an email

Having fun with Adobe AIR

Hi All,
this post will be in Italian, in particular is dedicated to the whole community of Italian mobile developers.
Having fun with Adobe AIR is a free event in 6 different Italian cities where people will learn how to create or improve own cross platform applications made with Adobe AIR for mobile devices.
For any question feel free to leave a comment to this post or drop me an email.

logoOfficial

Ciao a tutti,
mi chiamo Luca Mezzalira e sono l’organizzatore di “Having fun with Adobe AIR” un evento dedicato a tutti gli sviluppatori mobile che vogliono avvicinarsi ad una tecnologia cross-platform, come Adobe AIR, per la realizzazione delle proprie app o game su smartphone o tablet.
In collaborazione con alcuni importanti sponsor, come Adobe e BlackBerry per esempio, che ringrazio innanzitutto, sono riuscito ad organizzare 6 tappe in giro per l’Italia dove in una giornata andremo a scoprire le potenzialità di Adobe AIR, andremo a sviluppare degli esempi pratici che possano far vedere il workflow per la realizzazione di un’applicativo mobile.
Infatti l’evento è basato sulla formula BYOL (Bring Your Own Laptop) dove ogni participante dovrà portare il proprio computer con installato Flash Builder dove potrà creare i proprio applicativi e installarli poi nel proprio tablet o smartphone.

Se ti stai chiedendo se è una perdita di tempo perchè Flash è “morto”, beh credimi, non è così.

Infatti Adobe sta continuando a sviluppare questa tecnologia dando nuove potenzialità per la creazione di applicativi mobile e desktop, dall’accelerazione in GPU all’integrazione con Native Extension e molto altro ancora!

Durante l’evento avremo la fortuna di avere con noi degli speaker Adobe, in alcune tappe, che ci daranno la possibilità di scoprire su cosa si sta concentrando Adobe e quale sarà il futuro della piattaforma.
Un evento totalmente gratuito che credo possa far piacere in Italia a molti sviluppatori che vogliono iniziare a muovere i primi passi nel mondo mobile oppure quelli che già ci lavorano ma vogliono alternative valide con cui sviluppare.
L’evento avrà un massimo di 20 partecipanti circa per tappa e sarà di una giornata, le città in cui si svolgerà saranno Milano, Torino, Bolzano, Padova, Firenze e Bari.
La registrazione è obbligatoria e dev’essere fatta tramite il sito dell’eventohttp://www.havingfunwithadobeair.com/
Se invece preferisci seguirci direttamente sulla nostra pagina facebook ecco l’indirizzo: https://www.facebook.com/pages/Having-fun-with-Adobe-AIR/430003473713246

Per qualsiasi dubbio o domanda non esitare a contattarmi via email o lasciando un messaggio su questo post.
Spero di vederti ad una delle tappe del tour!
A presto

Luca

InDesign and Flash: PageFlip controller

One of our last project was to create an easy but integrated workflow from InDesign to web.
In particular they request us to create a PageFlip that will be published automatically online every change they made in the offline version without spending a lot of time on this activity.
Like you can see for a Flash Platform developer nothing more obvious that a project like this, so you can take a PageFlip online, you export all pages in swf or jpg files and you popolate the XML behind the PageFlip… yes but we don’t bring this direction.
First of all we suggest to our client to add interaction elements directly in InDesign because from CS5 version (if I remember well) it adds the animator engine of Flash, so it is quite easy make animations directly in InDesign for a graphic designer that is more comfortable with this software instead of Flash Professional.
After that we study the InDesign exporting settings and we find that you can have your PageFlip exporting InDesign document directly in unique SWF file; the only problem is that you haven’t any control panel to add interaction in your PageFlip, for example if my catalogue is composed by 300 pages and I have to see the 250, from the beginning I have to click 249 times on the right page to see my page.
Another interesting thing that we see during this development is that there are many PageFlip on the web but it’s not easy for a graphic designer, more focused on the paper, to customize them because you have to know how Flash works and in detail how the PageFlip, that you chosen, works too.
Also the PageFlip made by InDesign has great performance instead of any other PageFlip tested with many pages in particular if pages are vector based.
Finally we decide to decompile the InDesign PageFlip to analyze if we will able to create a control panel for this SWF file and… WOW… we really bring an interesting direction!


In fact, in the document class of the SWF file called IDSWFFile, you can find many methods that could help you to create, for example, a navigation panel to jump from a page to another one or to create an index to navigate trough chapters.
The main thing that you have to remember is that InDesign PageFlip works putting each page in a frame so if you have 20 pages you’ll have 20 frames inside the SWF file generated.

Below you can find some useful methods that could help you to develop your personal control panel:

  • getFrameCount() return the number of frames (so the number of pages inside the SWF file)
  • getCurrentFrame() return the actual frame (so the page that user is reading)
  • getThumbnailForFrame(frame:int, width=32, height=32) return a bitmapdata of a frame in the size that you prefer, the default values are 32×32 px
  • goToFirstFrame() goes to the first page of the PageFlip
  • goToLastFrame() goes to the last page of the PageFlip
  • goToPreviousFrame() goes to the previous page of the PageFlip
  • goToNextFrame() goes to the next page of the PageFlip
  • goToFrame(frame:int) goes to a particular page
  • stopAllAnimations()
  • stopAllSounds()
  • stopAllVideos() 

There are also other public methods but for me those are the most interesting to create a PageFlip controller.
To work with those methods you have to cast the content of Loader like a generic Object and then you can call all those methods like you can see here:

// here we create the generic object to call PageFlip methods
private var _pf:Object; 
// we load our file generated by InDesign
_loader = new Loader();
_loader.contentLoaderInfo.addEventListener(Event.COMPLETE, setPosition);
_loader.load(new URLRequest("pageflip.swf"));
//when PageFlip is loaded I add on the DisplayList
private function setPosition(e:Event):void{
_contPF = new Sprite();
_contPF.addChild(_loader.content);
addChild(_contPF);
_pf = _loader.content; 
}

// below I make functions to navigate the PageFlip when user click a button
private function prevPage(e:MouseEvent):void{
 _pf.goToPreviousFrame();
 }
 private function nextPage(e:MouseEvent):void{
 _pf.goToNextFrame();
}
 private function lastPage(e:MouseEvent):void{
_pf.goToLastFrame();
}
private function firstPage(e:MouseEvent):void{
_pf.goToFirstFrame();
}

If you’d like to create a more automatic workflow that allow your user to focus only on the content of PageFlip without waste his time with exporting issues.
In our case we use InDesign Server to solve this problem and create some scripts that allow user to create thumbnails and zoom pages without spend a minute on Photoshop or InDesign but easily upload own InDesign file on a server and via scripts we make everything user needs.
But I know that not everybody could have InDesign server in house, so another solution that I’d like to suggest could be create an InDesign panel with Flex that make the dirty job for the user, preparing all images for thumbs and exporting the PageFlip with right settings.

I know very well that it’s not rocket science for a Flash developer but I think that the workflow behind could be interesting and could be helpful in many situations and also I guess that InDesign users could find good stuff in this post.
Finally we have to remember that technology has to help people in their daily work accelerating process and maybe substitute the human interaction with a computer interaction giving more time to what people should be better like think to new stuff.

Flash Platform Galaxy: why choose Flash Platform

In those days I’m reading a lots of mailing lists, forums, blogs and so on where Flash Platform supporters are so disappointed about the latest marketing movement of Adobe.

In fact yesterday Adobe announced that they stop the development of Flash Player on Mobile devices (on Desktop they are going ahead).
The road is clear HTML 5 inside the browser and Flash Platform for RIAs, Games and out of browser in combination with Adobe AIR.

For me Adobe for the second time (the first one was during Adobe MAX) has totally mistaken how to communicate this news and obviously tech blogs bring this announcement like the end of Flash…
Personally I don’t think that is the end of Flash but I think that Flash is moving on a new position in multimedia world probably out of browser.
I’m an Adobe addicted, like you know, and in particular I’m a Flash Platform supporter, so I think that we have to move on and make something to spread the word about this foggy situation, guys, Flash Platform is ALIVE!
To do this, I start making a pdf file called Flash Platform Galaxy that could help people to have an idea of what is Flash Platform and why choose it ( I know, I’m not a graphic designer but I think it could be useful), if you want to add more informations or change something feel free to leave a comment at this post or drop me a line via email.
Let’s go guys, we have a platform to save ;)

It’s time for a new web design era… probably without Flash

I’m here in L.A. for Adobe MAX, before the beginning of the conference we were very excited about the 2 keynotes because we were waiting for amazing news about our favorite platform… but it didn’t happen, instead we find 2 days very focused to designers (and it’s normal I guess) and to HTML 5, JQuery and CSS 3.

This is an important signal from Adobe, in 2 keynotes they mentioned Flex 2/3 times maybe, all the new stuff for Flash was focused on games and 3D and AIR had only 5 mins to show the new release and its new features.

So the message from Adobe is quite clear: “Use HTML 5 for the web and Flash for the game and out of browser”.
This recommendation from Adobe would change online web design classes significantly in the future.

It seems crazy but it’s the truth… the same company that in the beginning of 2000 was scared from the little Macromedia and its best technology Flash, today substitued the player with a new one.

In latest years I took part of different Flash Platform projects, mainly desktop and mobile applications and I hoped to embrace the right direction with the Flash Platform, with this MAX I’m pretty sure  that I made the right decision.
I’m disappointed that my favorite platform will be out of the browser but I’m more disappointed that Adobe is following the market instead of make it.

Today I can say that it’s time to move on and start again to study new “trendy” technology instead of a good and solid technology like Flash Platform.
Could Flash be the new mobile and desktop technology? I really don’t know but I’m sure that this year a new milestone of the web was put by Adobe.

Playing with Google+ API and Actionscript 3

Yesterday I saw that Google has released Google+ API, so I started to played with in my favorite part of the day: the night!

For now Google has published only public APIs that allow you to retrieve user’s informations and his activities list, all API are made in RESTful and JSON that are so easy to add in your project.
When Google will release next APIs, I hope soon, you can consume them with an oAuth 2.0 authentication, like Facebook.
I made a simple example to retrieve data from my Google+ profile in Actionscript for Android, you can download the source files directly from here.

If you want to play with Google+ API, first of all you have to request your Google+ API key; to do that go to Google API console and activate Google+ service, then in the details page you can find your key.

Google+ RESTful services get us a JSON response, to read it in your Flash/Flex application remember that you need as3corelib that have the JSON deserializer, for example you can push in a generic Object all data retrieved from Google+ service or if you prefer you could create a Value Object that it could be more useful.
In this case I decode directly in a generic Object, like you can see in this code snippet:

var data:Object= JSON.decode(dataToRead, true);

then now you can easily access to informations:

var icon:String = data.image.url;
var name:String = data.displayName;
var tagline:String = data.tagline;
var description:String = data.aboutMe;

Another easy feature that you can add in your Google+ application is a static image of the map, like in your web page, using Google Maps Static API.
You can easily make a query to Google Maps passing in GET params like: the dimension of image, the location and the zoom; you can also add more params that you find in the docs of Google Maps Static API.
Here a code sample to add this feature in your Flash application, in those line I request for an image with width 480px, height 200px, with roadmap skin and with a zoom of 15x:

var mapLoader:Loader = new Loader();
//city is a variable with the name of the place that you have to retrieve.
mapLoader.load(new URLRequest("http://maps.googleapis.com/maps/api/staticmap?center="
+city+"&zoom=15&size=480x200&maptype=roadmap&sensor=true"));
mapLoader.y = this.stage.stageHeight - 200;
addChild(mapLoader);

Like you can see work with those APIs are pretty easy, so now we have to wait for final release and then we can start to create our Google+ integration with the Flash Platform.

Tricks for tween on mobile devices with Flash Platform

In this quick post I’d like to share with you my experience about Tween on Flash Platform projects delivered on a mobile devices.
I started work on mobile since Flash Lite 1.1 so I grew up with mobile, I lived all the Flash mobile evolution and now, on tablet and smartphone, I had some good tricks to share with you, I really hope that those tips could help you during your developer life.
OK, let’s start:

  • Use quality property of stage
    This is a really good technique to use when you have to improve performance of your project, when you need to make a fluid tween before launch it, set stage quality to low and when tween will finish set stage quality to high or best.
    Avoid to use this technique when you have vectors (textfield for example) on the stage because you could have a worst result.
  • Use cacheAsBitmap and cacheAsBitmapMatrix
    If you have vector object that you’d like to animate in your project remember to cache them and then animate; remember also to set your application with GPU acceleration and you can see a really good performance with this technique.
    Avoid to cache objects that you need to remove from display list, it will be so expensive for your memory.
  • System.gc() works!
    I tried in few sample to use it on Android and I saw a good result, so the “old” tip to call System.gc() twice in a try/catch statement works on mobile device too (only on AIR apps)
  • Take care with multiple animations on iPad and iPhone
    On iOS devices we don’t have AIR runtime so LLVM translate our AIR project for us in Native Binary so it could help if you move few objects per time in particular if you have big objects to move like a background or something like that
  • Greensocks tweens are the best
    I tried tweener and other tween libraries for AS3, but the best one for me are the Greensock tween library, in particular on iOS devices.
  • Last but not least, remember to test your animation on the device because you could see “funny” results
    Sometimes happen that on your computer everything works well but when you port your content on a tablet or smartphone everything works not so well.
    Before hurt your head, remember to test a lots of times your mobile content on the device, it could save your projects!
Finally I suggest to take a look at dev center mobile development zone of Adobe site because you can find many tutorials and helpful tips on mobile development.
That’s all folks for now, I hope you enjoy those tips.

Flash Camp Milan review

Yesterday in Milan we had the Flash Camp about Mobile topics and then we had the Flash Camp Party at NH Hotel… really wonderful time.
Like you know, in Italy it’s not so easy to organize those kind of events because usually people don’t move to another city like other foreign countries but Flash Camp had a great success.
This camp was organized in the same place of WhyMCA the mobile revolution, an italian conference focused on mobile topics.
We had 50/60 people per session and I’m glad to say that my session had 80 people so I’m happy about this little success.
All the sessions surfed in deep about CG, design patterns, video optimization for mobile, flex on mobile and so on, so I was really excited to take part in this event.
My session was about Design Pattern for Mobile, I talked about 3 design patterns: Singleton, Observer and Presentation Model.
With a couple of samples (that you can download from this link) and few slides I made an application that run with the same base code on tablet and smartphone; this is an hot topic now on mobile world in particular on Flash Platform side.

In next few weeks I’ll make a post about Presentation Model to share my thoughts about this argument and how to use it in your project , but if you want to start with this topic, take a look at this great post on RIArockstars.

Finally I’d like to thanks the Flash Mind, Adobe Flash Platform User Group Italy, to give me this opportunity, WhyMCA staff for the amazing organization, other speakers of Flash Camp for great time spent together and people that came to talk with us during the Flash Camp and to the beer party too.
I leave also a link to some photos took during Flash Camp in Milan.
