AIR apps developed using HTML+Javascript

Hi…
I am working on Adobe AIR.
And now I have 3 options to develop AIR applications 1)Flex
2) Flash 3) HTML+javascript.
But can you please explain me when do I exactly use Flex Or
HTML+JS Or Flash.
One of the reason I know is Flex used for Rich UI
applications
Is there any list of requirements for which one of the 3
option is most suitable to use.
And I have some more questions.
1) Can AIR applications(developed using HTML+Js) invoke a web
service running on a different server
2) Can AIR application(developed using HTML+Js) detect the
connectivity of USB drive (I have developed 1 application that can
detect the Network connectivity and periodically reports the status
I want the same in case of USB(plug & play) connectivity)
3) I have one AIR application that has one HTML form on click
of button I am posting the form Data to Java Servlet using
“air.sendToURL()” as shown
<script src="AIRAliases.js" />
<script>
function sendURL()
var url = "
http://localhost:8080/InvokingServlet/Registration";
var variables = new air.URLVariables();
variables.username = document.f1.username.value;
variables.password = document.f1.password.value;
var request = new air.URLRequest(url);
request.data = variables;
air.sendToURL(request);
alert("Data has been added to Remote DB...");
</script>
The data goes to Servlet and then Servlet thru Jdbc
Connectivity adds the data to database “MySQL” database
named “user”
If I read the data from database and print in Servlet it
displays that to “tomcat server window(log)” But I want
the data from Servlet to send back to HTML page where I can display
it on the same HTML page where user entered his details. So even if
I put the result into some Scope like session or request, but Can I
read that it in HTML+Javascript page .

This question gets asked about once a week. You
can find my latest answer
here
and a little searching will dig up more opinions.
quote:

service running on a different server
An AIR application isn't hosted on a server, so all web
servers are "foreign" to your AIR application. An AIR app does get
downloaded from a server, most of the time, but it doesn't maintain
some kind of special connection to that server.
Because of this, there are no cross-domain restrictions in
AIR like you have in a regular web browser.
quote:

connectivity of USB drive
AIR does not allow low-level system access, and has very
little in the way of platform-specific capabilities. So, you'd have
to use a high-level, platform-agnostic way of checking for the
drive, such as by looking around to see what files are available.
Things like USB insert notifications are way outside the scope of
AIR.

I want the data from Servlet to send back to HTML page where
I can display it on the same HTML page where user entered his
details.
That question isn't on-topic here. Ask on a forum dealing
with JSP servlets.

Adobe Air - HTML, Javascript and Threading

Hello,
I am developing an application using Adobe Air - HTML and
Javascript. What I am trying to do is to implement threading in
Javascript. I am using implementing threading in Javascript as per
this Neil blog.
Click
Here. It clearly says that this threading works only in Firefox
2.0 and I am trying to use this in with my Adobe Air, but when I
try to refer a function , it gives me error saying "unable to find
it".
I was wondering if this is the best way to go for threading
in Adobe Air HTML application or there is some other way also.
Thanks,
Jaikishan

Hi jjalan,
The yield and generator functionality is only available in
Firefox's javascript execution engine. When you are executing
javascript in AIR, it is done by the webkit and squirrelfish. Take
a look at
http://webkit.org/blog/189/announcing-squirrelfish/
If you can find a javascript library that works on safari /
webkit, chances are high that it may work in AIR.
Also, you can always do pseudo-threading via the age old
setTimeout()

AIR HTML+JavaScript app vs. hardware accelerated composing

I'm developing an HTML application for mobiles and desktops. The application is optimized for WebKit based environment. To improve a rendering speed I'm using hardware accelerated layers (something like -webkit-transform: translateZ(0); etc...).
This works great on my iOS devices (using PhoneGap aka Cordova to package a "native" app).
On Windows and OS X I'm using Adobe AIR 3.5 to package a captive runtime HTML/JavaScript based application. I have found this to be the best solution (for now) even though I have tried many others (Cordova for Windows 7 / OS X, TideSDK, ...).
The point is that the HTML rendering in Adobe AIR seems not to be hardware accelerated. Does anyone of you have experience with this? Is here any possibility to enable hardware accelerated layers in AIR HTML rendering?
Thanks a lot

Thanks a lot, actually I tried AIR SDK 3.6 yesterday and it seems it still doesn't support an acceleration. In a browser it works just fine even in fullscreen (zoomed page). It seems that the best way to achieve my goal will be using Cordova wrappers for OS X and Win Desktop. But as an AIR developer I really want to use AIR SDK So I will do some more tests..
Thanks,
Pavel

Leaking memory in AIR/HTML

Dear Adobe,
we need a little help fighting memory leaks in AIR 3/HTML application. Are there any tools or techniques you can recommend for this?
We have AIR app developed in HTML+JS, and the amount of memory consumed grows from 30Mb on startup to 90Mb in 4 hours to 190Mb in 8 hours on Windows 7. The app heavily utilizes XMLHttpRequest in long polling mode for communication. We are aware of the potential issue with keeping references to unnecessary objects and circular references and inspected our code for this, but did not find anything suspicious.
Would you please advise us on strategy - how to find and avoid memory leaks in AIR 3 with HTML? There was an Aptana plugin for AIR debugging, but it's only for AIR 2 and no longer useful.

null and removelisteners for everything when your done with them Timur,
Thats what I do and it works. But its still a pain stuff still mangers to get throught the net and takes me an age to track it down.
I manage some complex kiosks written in flash that are on 24hrs a day. Memory leakage is a massive issue for me.
So nulling anything and everything after use is my only weapon against memory leakage!
Apparently though... I think with the new multithreading techniques coming to air help manging leaks easier.

Bug in navigateToURL? (AIR HTML/JavaScript) window name parameter not working

Hi,
I have to popup the default browser from a HTML/JavaScript application.
All links on the Air page should be opened in the same tab in the same browser window that was opened by the first click on a link.
The code I use is
var urlString = "http://www.adobe.com";
var request = new air.URLRequest(urlString);
air.navigateToURL(request, "myNewWindow");
The myNewWindow parameter does not seem to be taken into account: a new tab is opened on every click.
I created a new Air application in Aptana and added the following straightforward code to it:
<html>
    <head>
        <title>navigateToURLTest</title>
        <script type="text/javascript" src="lib/air/AIRAliases.js"></script>
    </head>
    <body>
<a href="http://www.google.com"
            onclick="javascript:air.navigateToURL(new air.URLRequest('http://www.adobe.com'), 'AirTestWindow');return false;">New Tab</a>
        <br />
        <a href="http://www.adobe.com"
            onclick="javascript:air.navigateToURL(new air.URLRequest('http://www.adobe.com'), 'AirTestWindow');return false;">Same Tab</a>
    </body>
</html>
Same problem.
Does anyone have any idea?
Thanks

Is there really nobody who can answer or at least try to reproduce this?
It's just creating a new Air HTML/Javascript application with one link with a named window target!

AIR HTML component problem

I am using the AIR HTML component to load various website
directories with. However, any directory that gets loaded into the
HTML control that uses CAPTCHA, only loads maybe 2 pixels high
worth of the image. Is this a bug with the HTML control itself, or
have I failed to instantiate something? To see what I mean, try
loading this URL into AIR's HTML component.

I might add that this is flex 3 Retail version, not the beta.
Seems to work in the flex 3 milestone 4 beta.

Global error handlers in AIR/HTML

Dear Adobe,
there is good article on flobal error handling in Flex and AIR 2.0: http://www.adobe.com/devnet/flex/articles/global-exception-handling.html
Is there a global javascript exception handling mechanism in AIR/HTML? window.onerror does not work (that seems to be Webkit bug fixed in latest Chrome, but not yet in the AIR environment).

Dear Adobe,
any thoughts?)

Alert in adobe air / mobile development

I can't seem to do Alert.show like I do in regular flex apps,
I can't import mx.controls.Alert is there a equivalent in adobe air or how do you go about popping up error messages?

So is there Alert.show() for adobe air/mobile developement??? I was wonder it hasn't been added or is there an alternative for it?

Using Facebook SDK in Air HTML environment

Hi,
I am building an AIR application using HTML/JS and I'm trying to work with Facebook Javascript SDK for some simple functionality.
It seem however when running and an AIR environment I am not able to access the FB object.
I have the SDK locally so I know its there but simple FB.init() and FB.login() are non-existent and without errors...
I also tried using the FB AS3 library by incldeding it in <script> tags but this gives me an error
TypeError new window.runtime.com.facebook.graph.Facebook() is not a constructor
Don't know if its because my xml namespace is version 2.0 and not 1.5 (1.5 errors as well but it says some IFilePromise class is not found.
Can the Javascript SDK be used in building Adobe AIR HTML apps?

Annoyingly the SDK hasn't been updated in over three years. I've had a casual look via Visual Studio's object inspector to see if I can spot any new methods or properties that could be useful but if they are there then they are hidden well. Media Kind, for example, was introduced in iTunes 9, I think, but can't be read from code.
I don't know what tasks you're hoping to automate, but you might find some of my scripts useful either in their own right or as food for thought.

Consuming SOAP services from AIR/HTML (JavaScript).

Hi All.
I am trying to consume SOAP web services from an AIR/HTML application for a research on AIR I am doing for my company, and I am having very little success.
I am creating JavaScript clients using apache's cxf wsdl2js utility.
When I try to use the client to call any web service I've tried, I always get an 'error 500' response.
The web services work fine if i call them from other clients.
Before trying cxf generated clients I googled a lot to see if there was a more native way of doing these calls from AIR, but found nothing. I don't see anything in documentation or the web about it.
Am I the only one trying this?
Could this be a cross-domain issue? I'm certainly hoping AIR apps don't have this issue.
Any pointers as to how to succesfully consume SOAP services from AIR is greatly appreciated.
Thanks!

In Visual Basic, you can set Network Credentials like this (assuming that you first declare Public CallWebService001 As New <WebReference>):
        ' Create a new instance of CredentialCache.
        Dim mycredentialCache As Net.CredentialCache = New Net.CredentialCache()
        ' Create a new instance of NetworkCredential using the client
        ' credentials.
        Dim credentials As Net.NetworkCredential = New Net.NetworkCredential(<username>, <password>)
        ' Add the NetworkCredential to the CredentialCache.
        mycredentialCache.Add(New Uri(CallWebService001.Url), "Basic", credentials)
        ' Add the CredentialCache to the proxy class credentials.
        CallWebService001.Credentials = mycredentialCache

Adobe AIR HTML component ignores Google Maps GPolyline opacity

I have a Google Maps mashup web site that I want to display
in an
Adobe AIR app using the AIR HTML component. My mashup shows a
Google map with some semi-
transparent polylines (drawn as circles) drawn with the
Google Maps API . In Safari, everything looks
as it should. In AIR, the polylines are opaque; the GPolyline
opacity
value is ignored. I've tried the AIR app on Linux and Windows
XP.
Has anyone else encountered this issue or have some
suggestions?
The web site:
http://dstresearch.com/map.html
The AIR code:
<?xml version="1.0" encoding="utf-8"?>
<mx:WindowedApplication xmlns:mx="
http://www.adobe.com/2006/mxml"
layout="absolute" height="800" width="800">
<mx:HTML id="html"
width="100%"
height="100%"
location="
http://dstresearch.com/map.html"
/>
</mx:WindowedApplication>
Thanks,

You might also want to check out the useCache property to see if this helps. See these links:

Adobe air html/js - application act like a browser.

I just started in Adobe air html/js . In the current application I want to do something like this .
I want to open the urls/web pages in the application and application should act like a web-browser to them .
But with that I want to modify the opened pages a little, like add some css/js to them.
Something like when you open Web pages in Firefox and a plugin (example grease monkey scripts) modifies the displayed content .
Is it possible ?
I tried opening in iframe it works , but I cannot add my own JavaScript to the page (is there any way in air to remove cross domain strictness?).
Note: Please don't suggest that I fetch the html content of the page and add it to the app body. My app should really act as browser. (Adobe air is webkit based so I think it can be achieved)

Hi,
Thank you for reporting this. The internal bug number for the issue is #2740755. The issue is currently under review and will be investigated by one of AIR team members.

Catalin

AS3 Workers in Air HTML Environment?

Hi there,
I've begun to look into the practicality of running AS3 workers in my JavaScript based desktop AIR project. While I have not successfully nailed down a working implementation, it would seem that this is possible.
However, am I right to assume that I would not be able to leverage the WebKit HTML environment from within a worker?
Lastly, is anyone actually using AS3 workers within a AIR HTML environment? It seems to be an entirely unspoken feature within this context. It it not documented because this is just not possible?
Thanks,
Mike

Hi,
I've been doing some work trying to get an AS3 worker running from the webkit enviroment and am having a really strange problem. As soon as I start the worker, the worker starts chewing through all available CPU. No messages are being passed, it has just been started.
Here is an example of the worker:
package DDX
     import flash.events.Event;
     import flash.system.MessageChannel;
     import flash.system.Worker;
     public class Worker
          private var mainToBack:MessageChannel;
          private var backToMain:MessageChannel;
          public function Worker()
               var current:flash.system.Worker = flash.system.Worker.current;
               mainToBack = current.getSharedProperty("mainToBack");
               backToMain = current.getSharedProperty("backToMain");
               mainToBack.addEventListener(Event.CHANNEL_MESSAGE, onMainToBack);
          private function onMainToBack(event:Event):void
               if (mainToBack.messageAvailable) {
                    var msg:* = mainToBack.receive();
                    if (msg == "SOLVE") {
                         backToMain.send("SOLVED");
And here is how I set it up in JavaScript:
var workerLoader = new air.URLLoader(),
    mainToBack,
    backToMain,
    bgWorker,
    workerBytes;
workerLoader.dataFormat = air.URLLoaderDataFormat.BINARY;
workerLoader.addEventListener(air.Event.COMPLETE, function(event) {
    workerBytes = event.target.data;
    bgWorker = air.WorkerDomain.current.createWorker(workerBytes);
    mainToBack = air.Worker.current.createMessageChannel(bgWorker);
    backToMain = bgWorker.createMessageChannel(air.Worker.current);
    backToMain.addEventListener(air.Event.CHANNEL_MESSAGE, function() {
        if (backToMain.messageAvailable) {
            var msg = backToMain.receive();
            console.log('RECEIVED ' + msg);
    }, false, 0, true);
    bgWorker.setSharedProperty("backToMain", backToMain);
    bgWorker.setSharedProperty("mainToBack", mainToBack);
    // listen for worker state changes to know when the worker is running
    bgWorker.addEventListener(air.Event.WORKER_STATE, function(e) {console.trace(e)});
workerLoader.load(new air.URLRequest("assets/flash/DDXWorker2.swf"));
As soon as I start the worker, CPU starts being eaten up entierly:
bgWorker.start();
No messages being sent via the channel, just the worker started.
Any ideas?
Thanks,
Mike

Is there a way to download inside AIR HTML?

Hi,
Is there any way to download files from the webpage running inside AIR HTML component? i.e. mail attachment etc.?
Thanks!

I'm already overriding loaded HTML page's links etc. but yes its true to determine which link is for download or to open just a web page.
StageWebView!! I was in impression for a long time, this made for mobile! After you saying so, at help.adobe.com I can see this also for all desktop operating systems too! Great!
Though our existing ol' HTML component is already coded/modified heavily through the application, I don't know how far we can replace them with new StageWebView.. but you simply given me an option. Thanks!
I'll see a simple demo how enable it is downloading files in an AIR application, shortly.
