Flex Air Apps on Blackberry

I've had a Flex Air app on Playbook since it Adobe first supported Blackberry. But, I haven't had a client requirement for deploying to Blackberry in a long time. What is the status on Adobe's support for Blackberry? On the Air Dev Center, I see no references to Blackberry anymore???
Can I still build a cross-platform app for latest Blackberry devices (Blackberry 10, Playbook, etc.) using the standard Flex mobile components and Flash Builder 4.6?
After a brief search on Blackberry's Air page, it looks like they moved to requiring the QNX components, ANEs and a new pure AS3 SDK only. If I have to re-write code specific for Blackberry now, then it makes no sense for me to offer that to my clients. (unless they only want BB).
So, where does Adobe stand now with Flex Mobile in Flash Builder deploying to Blackberry 10 and the Playbook?
I'd appreciate if you could help bring me back up to speed.
Thanks,
Don

Absolutely, Flex works very well indeed and is fully supported on BlackBerry PlayBook and BB10 devices. The free packaging module for Flash Builder is part of the BB SDK for AIR and is supplied by RIM, not by Adobe.
With Flex you'll of course be using Adobe UI components, which look less native than the BB-supplied "pure AS3" UI components unless you skin them. But they work just fine.

Example working Flex AIR app for Android?

I'm having trouble getting even the most basic AIR app working on Android. Here is the code:
<?xml version="1.0" encoding="utf-8"?>
<s:WindowedApplication xmlns:fx="http://ns.adobe.com/mxml/2009"
                        xmlns:s="library://ns.adobe.com/flex/spark"
                        xmlns:mx="library://ns.adobe.com/flex/mx" xmlns:local="*"
                        width="600" height="600">
     <fx:Declarations>
         
     </fx:Declarations>
     <mx:Label text="Hello World"/>
</s:WindowedApplication>
It works fine running on Windows in Flash Builder, obviously it's pretty simple. Here are the commands I use to put it on a Samsung Galaxy Tab with Android 2.2.

A Test2 app icon shows up on my Galaxy Tab under Applications but when I run the app I just see a plain white screen, I don't see the words "Hello World". Any ideas? Does anyone have an example Flex AIR app that works on Android and can post the code so I can try it on my Galaxy Tab? I know AIR is installed correctly on my Galaxy because I installed an AIR app called South Park Avatar Creator that I got from the market and it works fine.
Thanks,
Ryan
P.S. Here is the Test2-app.xml from my non-working project above in case it helps. This is the default generated with a new Flex app in Flash Builder 4 using the Flex 4.1.0 AIR 2.5 SDK but I uncommented the andoid tags and set the visible tag to true.

Flash performance inside mx:HTML in a Flex AIR app

Hi. I'm new to AIR development and after doing some basic tutorials I thought I'd make a little stream player app.
The amount of tutorials on the web made me choose Flex / Flash Builder over HTML & JavaScript. When I built the player in Flex I saw performance was terrible when out of focus, I would say it drops to 3 fps if not less. Surprisingly when I downloaded someone else's similar app, his didn't have that problem. On closer inspection - he made it in HTML & JavaScript and HTML AIR apps dont suffer from the same problem.
Is there a fix for this Flex performance problem?
I've made a video demonstrating the difference between Flex & HTML for your convenience: http://www.youtube.com/watch?v=OU2mfELhSC4.

Sure.
1.
Windows 7 Ultimate, 64bit, build 7600.
Adobe AIR 2.0.3.13070.
Unfortunately I only have machines with the exact same OS install at my disposal right now but I'll ask some people to test it on their boxes.
2. http://pastebin.com/AsdmD3Yb
When I point the mx:HTML to a youtube url instead of ustream.html the fps drops around to around 5 to 10. That's a lot more fps than when using ustream. Might be a clue to whats happening.

A way to expire an FLEX/AIR app?

Using Flex 3 I would like my AIR app to expire in 30 days after install. Anyone have any advice or example of this?

You need a wireless flash drive.

Google Trends in flex/AIR apps

Browser inside a Flash/FLex/Air-App with WebGL-Support?

Hello,
I´m using Adobe Air/Flex to build a Desktop App. Inside the App the user should be able to access an Internet Browser. This part is actually working so far.
BUT: THE ADOBE AIR BROWSER IS NOT SUPPORTING WEBGL.
Is there any method to activate the WebGL Support so I could open WebGL-Dependent URLs from Inside my Desktop App?
Sure, I could tell the User he should Alt+Tab to switch to an WebGL-Compatible Browser, but it would so much better if this all would work from inside my Application.
Thanks for answering!

The syntax for the update is incorrect, you can use the update statement as
sqls.text = "UPDATE videos SET thumb = 'ram' + '''s' where id = 2";
Let me know if this worked.

Flex Air App... and SQLite

I was hoping someone can point me in the direction to learn the SQLite on Adobe Air... I need something simple to start out... Most of what i found is rather complicated, and get's kind of confusing...
Do you have to create the database at run-time?

SQLite error in Flex/Air App:

I am trying to do a simple SQLite query from inside and Air application:
Statement.text = 'SELECT Ingredient' +
'FROM Ingredients'+
'WHERE FoodCatagory_FK = 6'
It works just fine in when I exicute the query in SQLite Manger, however in Air I get the follwoing error:
SQLError: 'Error #3115: SQL Error.', details:'near 'FoodCatagory_FK': syntax error', operation:'execute', detailID:'2003'
Not sure why it does not work, it seems pretty strait forward.
Thanks,

Hi,
You have to leave a space either after
Ingredients
or before
WHERE FoodCatagory_FK

Convert HTML/javascript AIR app to flex-based AIR app?

Hi all,
I've already built an AIR app using HTML/javascript that I
would like to monetize.
I would like to use O2app's E-Commerce framework, which right
now only supports Flex-created AIR apps.
My question: Is there a simple way to "convert" an
HTML/javascript AIR app to Flex 3 format? I'd rather not have to
rebuild the app from scratch in Flex 3 if I don't have to. :)
Thanks,
Al

Hi,
There's no simple way to convert an HTML AIR app to flex.
But it is possible to create HTML Root windows from a Flex
AIR App. By root window, I mean the same kind of window that is
launched when you launch an HTML AIR App.
For more info, look at the HTMLLoader.createRootWindow()
call. (This will be available from a Flex AIR app as well)

AIR app and Flex app in same Flex builder project

Hi,
I've developed a flex app with a lot of custom components.
Now I want to create a desktop version of the same using the same
exact same components. Is it possible that I add an mxml
application, make it a WindowedApplication and compile it to
produce an AIR app? Or are there any workarounds to accomplish
this.

Easiest way I have found is to complete your Flex Web app.
Then create a new Flex AIR app and then copy code from your working
Flex Web app over.
Yes, you end up with two complete sets of code, but if that
is going to become an issue with keeping both versions up to date
you can simply use one set of source.
To do this, create two projects, one Web, one Air. Then you
can create a third folder (not project) that contains all the
common code.
In each of your projects, simply import the code you want to
use using the project options.
No, not ideal, but does work. Would be nice to see Flex
Builder changed so you can have rooted projects.
E.g. A project called "MyBigApplication" that isn't targetted
at any platform. Within this you could then produce sub-projects
that target a particular platform, be it web or air but share code.
Maybe in the next version.....

Using browser javascript to copy selected text from a pdf file opened in Air app.

I have posted this question on reader forum as well, but I think it is more suited here...
I am trying to create a note-taking application in air. I want to extract selected text from pdf file as a string object or to the clipboard.
Obviously, all pdfs in my local storage will not be scripted to recieve postMessages and act accordingly, and that is not practical either. So, my problem is, how can I copy the selected text in the pdf file (opened as an object in htmlloader within my Air app) to clipboard or directly in another control by say clicking a button in air application? I suppose, this is possible using javascript, however, I don't know which reader methods are exposed to the wrapper htmlloader control. In short, I want to execute app.execMenuItem("Copy") command through htmlloader javascript. Any alternate solutions are also welcome.
This is similar to passing inbuilt commands/methods/functions (of adobe reader) to pdf-reader plugin embedded in a webpage via javascript. This is possible in IE where the pdf is rendered as activex object, and hence JSObject interface of pdf document/reader is accessible to the browser javascript. I have also read that this same JSObject is accessible to VB as interface for IAC, so as the Air is Adobe's own product, I was wondering if equivalent of JSObject is accessible to htmlloader control as well.
Thanks in advance...
Mits

Thank you Thom for your reply...
from
http://www.adobe.com/devnet/acrobat/javascript.html
...Through JavaScript extensions, the viewer application and its plug-ins expose much of their functionality to document authors, form designers, and plug-in developers...
As it is explicitly mentioned, that the functionality of adobe reader are exposed for plugin development, I thought someone here might have used external javascript to execute some safe methods in adobe reader. The functionality (i.e. external javascript interface-JSObject) is already available for VB programmers to develop IAC. Further, the Acrobat SDK example called "AcroPDFinHML" shows how one can embed a pdf-reader in a html page and execute some safe methods (like gotonextpage(), zooming etc.) in IE as ActiveX plugin. I have checked it myself for adobe reader 9, and it works perfectly, so there is no security issue as such to implement the same for another browser (like in my case, the htmlloader control in flex/air app).
I intend to create a note taking application in air, where it is very much required that I should be able to copy selected text from various pdf documents, that are open in my app, and subsequently paste/collect/save the collected notes and process them afterwords (offcourse, from the pdfs that allow me copying text). However, it is not happening for me here. As the pdfs are opened through adobe reader plugin, it does not register the copy command executed by my air app. It registers the system level copy command (by keyboard shortcut Ctrl+C), but my air app has no way to execute the system level copy command programmatically. So I am kind of stuck here...
Thanks again for your reply. Having known what am I intend to accomplish, any other (may be alternative) solutions will be appreciated nonetheless...

Adt code sign GateKeeper rejection for OS X AIR app

I'm having a problem getting a signed OS X AIR captive runtime bundle app to pass the GateKeeper signature smell test.
Here are the digestible facts, in list format:
- App is multi-platform OS X, Windows, iOS, Android, but let's just focus on OS X for now.
- Application is a standalone captive runtime bundle app.
- Dev machine running OS X 10.9.5 (with Xcode 6.0.1).
- Built with AIR 15.0.0.258 Beta.
- The certificate is a certificate from comodo.com guaranteed to work with AIR and OS X Digital Code Signing, Code Signing Certificates - COMODO
- Tried compiling/packing with IntelliJ IDEA 14 beta and adt command line, both with same fail results.
- Manual packaging method used: Adobe AIR * Packaging a captive runtime bundle for desktop computers
The adt command fires without a hitch, the command asks for the p12 password, I can see the certificate authorities get pinged as the packaging progresses. The resulting app seems fine and runs well with GateKeeper disabled. However, GateKeeper does not like the resulting app. I need this app to launch flawlessly on all user's systems (that's why I bought a certificate).
Here's the disappointing results from Terminal:
spctl -a -t exec -vv myPrettyPony.app
rejected
source=no usable signature

I would suggest that those interested take a look at thread Tutorial on publishing Flex/Air app for Mac App Store or just using Developer ID for general distribution
However, since that thread is marked as answered, I want to leave this thread open until I find an answer to my particular question: What are the exact steps to properly package and codesign an OS X AIR app for independent distribution to OS X 10.9.5?

Output xml file from data in a drag/drop AIR app.

I am interested in creating a WYSIWYG drag/drop AIR app. in
which I can drag art and other components, then export the (x,y)
positions of the components and other info into an xml file. I am
interested in using .ai files instead of raster based art. Will
Flex/AIR app. support this format? I am just starting to work with
Flash, Flex, etc. Is this way over my head? Possible?
Thanks,
Nate

I don't think you can manipulate .ai files in Flex /
AIR.
