My Flex web application is almost ready for launch. I'm currently optimizing as much as I can in order to make sure even low-end clients are able to run it fluently. The problem is, I have no idea where to optimize more than I've already optimized. My question is, what are the usuals suspects regarding bottlenecks? What tips and experiences do you have when it comes to Optimizing a Flex app?
View 4 RepliesI'm working with Flashpunk to make games using Flex and FlashDevelop (highly recommended, amazing lib and IDE). Since performance varies so much from system to system, I want to find where slowdowns are occurring and only fix those bits. Flashdevelop has a built in tool called Profiler, but it only shows the number of objects and the memory they are using, not the execution time. Grant Skinner wrote a great tool called PerformanceTest, but it seems suited to writing very specific optimization comparisons, not automatically profiling your code.
What I'm trying to find is a tool that will automatically analyze the program while it's running and tell me which functions are taking the longest to execute. I've heard that CS5 has this built in, but I'm wondering if there are any alternatives.
I have a Flex 4.6 web game which displays 2 Lists with virtual layouts with 2 custom item renderers. The renderers consist mainly of BitmapImages displaying user avatars + few Labels.
The Lists are being updated often over TCP socket with gzipped JSON data. I merge that data into 2 ArrayCollections serving as dataProviders for the Lists. This seems to work well, the Lists do not flicker and are updated correctly (I've monitored debug traces a lot to get it right).

How to find where is memory leak in a flex application?
Are there some tools to catch and analyze this problem?
I need to disable all the aspects of functionality which access the client file system in a flash/flex application. I started having a look on how to do this. It appears that the package flash.filesystem need to be importated to allow the interaction with the file system. However, I did not find any reference to this package in the application. I am a beginner concerning these technologies so maybe I am missing a point here. Do I need to look into an other direction?

Flex Framework as RSL

We believe we spent a lot of time into asset optimization and most of the work is remaining on the code.By analyzing our link-report, our guess is that the heavy part of the code is comming from Flex .mxml nested components. We don't think there is much to do on our pure AS classes.Is there any analysis or coding best practice in order to reduce the impact of the code on the swf filesize ?
I know ADG related questions generally get ignored because "it's a crappy component". Indeed, it is not one of my favorite pieces of code ever, but I'm stuck with it and have been working (pretty hard) at optimizing its performance. Turns out there's a fair amount of stuff one can do to make things go fast. One thing I've been stuck on, though, is not to optimize adding an element to the underlying dataprovider. Say you want to add a row to the ADG using a addChildAt call on the DP. All seems well but the operation is so slow - it's unbearable. Now, I realize that the ADG may need to redraw all the stuff below the line added, but seriously, in 2011 that should not take a load of time and 100$ of my CPU. Does anyone know what may be the main culprit?
Note: I'm able to catch the CollectionEvent of kind "add" and not deliver them to the ADG, which I thought would do the trick, but the ADG still updates and takes forever to do so, so I'm guessing there's something else somewhere else.
I'm working on some photo manipulation stuff and have multiple images loading and displaying ontop of each other, each with various blendmodes set e.g. overlay, multiply etc.
The problem is it is sooooo slow! I thought I might be able to optimise it by drawing the resultant image to a new bitmap using BitmapData.draw (so sort of pre-baking the effects). The problem is (as I understand it) blendmodes are not draw when not on screen, so I can't use this approach until I've added the images to the screen at which point it has already slooowed down.
I was wondering if an AIR application can find out what OS it's running on, e.g. Windows XP, Vista, Mac OS, etc. Also, is there a way for it to find out the current OS user name?

View 1 RepliesI'm trying to develop a simple mxml Flex application to start Skype from the AIR/Flashplayer runtime. Is it possible to get back events from a native Windows application? In the simple example of Skype, the OS returns control to the Flex app when Skype exits. But what about native applications which have their own event model and wants to communicate with the Flex event model. For example, a Face detection system which shows "Hello" on a Flex app when the camera detects a face. Can this be done in the current Flex framework?

how can i delete storage directory instances or folder while uninstalling any air application. In my application when i first time run my application, application copy some data from application directory to application storage directory. now i want to delete all data and application directory folder also while uninstalling application.
I am doing that because when i launch any update then application is accessing old data which conflict with my application new features.
I'm new to flex. Now I'm writing an flex application. I plan to split my application into some MXML files(Application as the root tag).

View 1 RepliesI have a native (Obj-C, standard Xcode project) application and I'd like to integrate a partners iOS application (or specifically, it's functionality) into it as just another view in my application. The problem is that their application is a Flex/Air app. I really don't understand the Adobe compilation process on how it gets from a bunch of flex code down to an IPA. I don't see intermediate projects, shared objects, etc on the disk to produce that IPA. It looks like it doesn't rely on the Apple tool chain... as I understand it, you can produce the IPA on Windows as well. Is there any way to build that Flex app in such a way that I can import it into Xcode so I can link against it and use it as a library from within my application? While I specifically used iOS as an example since that is the most important platform, we'll want to apply this solution to our respective Android and Blackberry 6 apps as well.
View 1 RepliesI have an AIR application with a system tray icon. When clicked it shows and activates the app. This is working as expected when the app is hidden (docked), however if I select another application so my app is in the background clicking on the system tray icon does nothing.
Oddly I also have a contextual menu on the system tray icon, which has an option to restore, this calls the same event handler as ScreenMouseEvent.CLICK, yet works.
I expect it's something to do with the contextual menu changing the focus, perhaps it's a bug in how AIR works with the system tray, perhaps it's just something I'm missing. Would be good to know if that's the case.
I've been trying to launch a separate Air Application through my current Air Application.Both apps are compiled using the Adobe Air 2.0 SDK. The methods I have found so far involve passing the Publisher ID in addition to the Application ID, but I believe the Publisher ID became redundant past Air 1.5.3? Below is my current implementation whic seems to correctly ascertain the Air Application's version number, but when I try to launch it, nothing seems to happen.

private static var _loader:Loader;
