Just a quick tip for those looking to somehow display the AIR application version from the descriptor file. I’ve found it very helpful in troubleshooting is users can say EXACTLY what version of the app they are running.
AIR 2.5 and later:
private function getAppVersion():String {
var appXml:XML = NativeApplication.nativeApplication.applicationDescriptor;
var ns:Namespace = appXml.namespace();
var appVersion:String = appXml.ns::versionNumber[0];
return appVersion;
}
Older versions of AIR:
private function getAppVersion():String {
var appXml:XML = NativeApplication.nativeApplication.applicationDescriptor;
var ns:Namespace = appXml.namespace();
var appVersion:String = appXml.ns::version[0];
return appVersion;
}

Looks like in AIR >= 2.5 the version property is defined as ‘versionNumber’, not the older ‘version’.
This is correct.
Your code is black text on black background. Not the best combination :)
Yikes! Thanks for pointing that out. It was using an older syntax highlighter – should be fixed now.
Thanks , really helped saving time writing it in manually.
Thanks. Saved me precious time!
Sadly it’s not working on Flex 4.6 AIR 3.3. And it took me more than an hour and I can’t find the solution yet.
AIR 2.5 and greater requires :
var appVersion:String = appXml.ns::versionNumber[0];
I’ve updated the post to reflect this change.
work Flex 4.6 Air 3.3
protected function init():void
{
var appXml:XML = NativeApplication.nativeApplication.applicationDescriptor;
var ns:Namespace = appXml.namespace();
var appVersion:String = appXml.ns::versionNumber[0];
trace(appVersion);
}
THANK YOU VERY MUCH !!!!
Thanks,
Exactly what I needed!
