Flex “Output from command: error while loading initial content” fix

Posted by Michiel on Thu, January 7th, 2010 in Flex

If you are having problems getting a new SDK installation to work with Flex Builder 3 (e.g. if you’re trying to compile a Flex project as AIR application using Flash Player 10) and get the following error:

Process terminated without establishing connection to debugger.
Command:
"C:\Program Files (x86)\Adobe\Flex Builder 3\sdks\3.5\bin\adl.exe" "projectPath" "bin-debug location"
Output from command:
error while loading initial content
Process terminated without establishing connection to debugger.
Command:
"C:\Program Files (x86)\Adobe\Flex Builder 3\sdks\3.5\bin\adl.exe" "projectPath" "bin-debug location"
Output from command:
error while loading initial content

here is the solution, thanks to Jim Hayes.

In your project, there’s a file called <yourApplicationName>-app.xml. Open it and change the following:

<?xml version="1.0" encoding="UTF-8"?>
<application xmlns="http://ns.adobe.com/air/application/x.x">

to:

<?xml version="1.0" encoding="UTF-8"?>
<application xmlns="http://ns.adobe.com/air/application/1.5">

That should solve your problem.

I’m facing similar issue, but it’s not getting fixed with this.

Here is the error:

Process terminated without establishing connection to debugger.

Launch command details: “C:\Program Files\Adobe\Adobe Flash Builder 4.5\sdks\4.5.0\bin\adl.exe” -runtime “C:\Program Files\Adobe\Adobe Flash Builder 4.5\sdks\4.5.0\runtimes\air\win” “C:\Program Files\eclipse\FB45\ZeroShrinkClient_FB45\bin-debug\myApp-app.xml” “C:\Program Files\eclipse\FB45\ZeroShrinkClient_FB45\bin-debug”

Jims -> I solved this same error playing with the –swf-version compiler argument

When I update -app.xml with latest air version I am getting the error of unknown namespace

@Shridihar: I’ve not been using Flex for a while, so I’m not aware of changes in the latest versions.

My guess, however, is that it has something to do with XML namespaces. More info about that can be found
http://www.w3.org/TR/REC-xml-names/#ns-decl
and
http://en.wikipedia.org/wiki/XML_namespace

Cheers!
