I'm porting an AIR1.5 application to AIR2.0, and getting stuck at the first hurdle.
adt doesn't seem to recognise the 2.0 namespace.
I'm using the latest command line tools to build the application. This is what I'm typing...
amxmlc -library-path+=../libs/AdobeSpelling.swc -library-path+=../libs/as3corelib.swc E2Publish.as
adt -package -storetype PKCS12 -keystore mypfx.pfx -storepass XXXXX e2publish.air E2Publish.xml E2Publish.swf E2Picons/AIRApp_16.png E2Picons/AIRApp_32.png E2Picons/AIRApp_48.png E2Picons/AIRApp_128.png usa.zwl
<?xml version="1.0" encoding="UTF-8"?>
<application xmlns="http://ns.adobe.com/air/application/2.0">
...but it is otherwise the same as the xml file that worked fine for my AIR1.5 application.
SO - what am I doing wrong?
