DatagramSocket on mobile AIR 3.8

[lewispeel]

I've created a really basic project to test the DatagramSocket in AIR 3.8 & Flash Player 11.8, but the DatagramSocket.isSupported property is coming back as false...even though Adobe says it is supported on Android & iOS.

Another new feature is ServerSocket, when I trace that out it comes back as true. Has anyone had trouble using this?

Capabilities.version = IOS 11,8,800,49

NativeApplication.nativeApplication.runtimeVersion = 3.8.0.440

DatagramSocket.isSupported = false
ServerSocket.isSupported = true

You need to be on 21 swf version, please set -swf-version=21 in your compiler options.

Hi Pahup,

Thanks for you reply. I've tried adding that compiler argument but it didn't fix it. What confuses me is that I'm seeing 11.8.800.49 when I trace out the player version...isn't that correct for -swf-version=21?

[Pahup]

And how about the namespace of your AIR application, is it 3.8?

Yes that's also correct;

<application xmlns="http://ns.adobe.com/air/application/3.8">

It's weird that one new 3.8 feature (ServerSocket) works, but another (DatagramSocket) doesn't. Have you tried making an ActionScript Mobile Project which targets AIR 3.8 and trace out DatagramSocket.isSupported? I would be interested if the same happens to you.

If I create a release build and put it on my iPhone, DatagramSocket isn't unsupported. But if I create a debug version using exactly the same code and put that on my iPhone...DatagramSocket IS supported. I'm confused. Do I need to change some permissions in the XML descriptor?

[lewispeel]

Right, so I've gone the whole way and created a release build with 'UIRequiresPersistentWIFI' set to true in the descriptior XML and that seems to work when I create a release build. But if I run a debug build in Flash Builder I get isSupported=false again.

At least I know it works on the device with this setting turned on but that makes it impossible to develop with as I really don't want to create and deploy a release build to my phone every time I want to test the smallest changes.

Could you please check and share the swf version used for both release and debug build you used. The easiest way to identify the swf version is by using swfdump-cli.jar available as the part of the SDK.

java -jar AIRSDK/lib/swfdump-cli.jar mySwf.swf

Hi Nimit,

I've never used that  before. How do I use it?

*edit* I'm using a Mac by the way, if that makes a difference.

Please use the following command on the terminal : java -jar AIRSDK/lib/swfdump-cli.jar mySwf.swf ,  the command will work on both win/mac.

[lewispeel]

Ok thanks, I will try that and post the results. Out of interest, are you seeing the same issue?

[nimitja]

No, it's working fine with both release and debug build.

[lewispeel]

Ok, so I just created a blank ActionScript Mobile project, targeted the AIR 3.8 SDK, made sure my descriptor XML has 3.8 namespace, added "-swf-version=21" into the compiler options, compiled a debug build and traced out a few values.

Capabilities Version IOS 11,8,800,49

Runtime Version 3.8.0.440

DatagramSocket.isSupported false

Thanks lewi-p for your help, the bug is reproducible with ADL, should be fixed in next week's 3.8 labs build.
