Flex – Adobe Air – Opens the file with air

< mx:WindowedApplication
 xmlns:mx="http://www.adobe.com/2006/mxml"
 xmlns:s="spark.components.*"
 invoke="onAppInvoke( event);">
  import mx.controls.Alert;

 private function onAppInvoke(event:InvokeEvent):void {< br /> if (event.arguments.length>0) {
 // ok app call with an arguments
 var fileName:String=event.arguments[0];
 Alert.show( "app open with: "+fileName);
} else {
 // app open normally
 Alert.show("normal launch");
 }
} 
 ]]>

So I created an Air application that can be saved as Custom file type. I set the file association when publishing the application. When you double-click the file, it will open the air application. Is there any hook to detect that the application is opened through the file? Obviously, I need to detect this and then let the application open the file itself.

Listen to InvokeEvent, it will save the arguments property of the requested file name:

Quick mxml example:

 xmlns:mx=" http://www.adobe.com/2006/mxml"
 xmlns:s="spark.components.*"
 invoke="onAppInvoke(event);">
  import mx.controls.Alert;

 private function onAppInvoke(event:InvokeEvent):void {
 if (event.arguments.length>0 ) {
 // ok app call with an arguments
 var fileName:String=event.arguments[0];
 Alert.show("app open with: "+fileName);
} else {
 // app open normally
 Alert.show("normal launch");
 }
 }
