Question

I’ve been trying to launch a separate Air Application through my current Air Application.

Both apps are compiled using the Adobe Air 2.0 SDK.

The methods I have found so far involve passing the Publisher ID in addition to the Application ID, but I believe the Publisher ID became redundant past Air 1.5.3?

Below is my current implementation whic seems to correctly ascertain the Air Application’s version number, but when I try to launch it, nothing seems to happen.

private static var _air:Object;
private static var _loader:Loader;

private static var appID:String = "someOtherAirApplication";
private static var pubID:String = NativeApplication.nativeApplication.publisherID;  

public static function loadAir() : void
{
 _loader = new Loader();
 var loaderContext:LoaderContext = new LoaderContext();
 loaderContext.applicationDomain = ApplicationDomain.currentDomain;
 _loader.contentLoaderInfo.addEventListener(Event.INIT,onInit);
 _loader.load(new   URLRequest("http://airdownload.adobe.com/air/browserapi/air.swf"),loaderContext);
}

private static function onInit(event:Event) : void
{
 _air = event.target.content;
        //the pubID argument resolves to and empty string ""   
        _air.getApplicationVersion(appID, pubID, versionDetectCallback);
}

private static function versionDetectCallback(version:String) : void
{
if(version != null)
{
_air.launchApplication(appID,pubID);
}
}

I have changed the app-config.xml (app descriptor) on the application I am trying to load to allow browser invocation.

The version number of the app descriptor of my application I am trying to load is “V1” which the versionDetectCallback seems to pickup. If this is the case I would expect to be able to launch it but this doesn’t seem the case.

Any ideas?

It seems the issues I was facing, after finding appropriate documentation, was that my method

_air.launchApplication(appID,pubID);

needed to be called from a user generated event, such as a click handler.

Also it seems the publisher ID is not a required attribute and an empty string can be passed instead.

EDIT: Added example below.

//This method is called from a user initiated event, in this case a mouse click on a button
private static function versionDetectCallback(event:MouseEvent,version:String) : void
{
    if(version != null)
    {
       _air.launchApplication(appID,pubID);
    }
}
