Can't Launch Air Apps after upgrading Flex Builder to 3.0.2

Posted At : January 13, 2009 8:33 PM

I recently upgraded flex builder to 3.0.2 to play with the new Flash 10 goodness and came across this little problem.

Whenever I clicked run it would just sit there for ages and never launch the app. If I clicked debug I got the following error:

Process terminated without establishing connection to debugger.

Command:

"C:\Program Files\Adobe\Flex Builder 3\sdks\3.2.0\bin\adl.exe" "C:\Documents and Settings\markl\My Documents\Flex Builder 3\SampleApp\bin-debug\SampleApp-app.xml" "C:\Documents and Settings\markl\My Documents\Flex Builder 3\DexterAir\bin-debug"

Output from command:

error while loading initial content

Turns out the solution is easy when you know how, thanks to this post.

The solution is a simple as changing the namespace in the app.xml file from:

<application xmlns="http://ns.adobe.com/air/application/1.0">
to
<application xmlns="http://ns.adobe.com/air/application/1.5">

Which is fine if you want to upgrade you app to 1.5 - not sure if there is still a way to compile apps for AIR 1.0 though.
