Debug AIR applications with Charles Proxy

Here’s a little trick to allow Charles Proxy to debug your Adobe AIR AMF-based applications whilst developing on your localhost.

Open up your “hosts” file in a text editor:

Windows
Windows NT/2000/XP Pro c:\winnt\system32\drivers\etc\hosts
Windows XP Home c:\windows\system32\drivers\etc\hosts

Linux
/etc/hosts

Macintosh OS X
Finder -> Go -> Go to folder
search for /etc
Open up “hosts” in your text editor.

Add the domain “localhost.” to your 127.0.0.1 line, (Note the fullstop!), it should now read something like:
127.0.0.1 localhost localhost.

Save & close. (You may need to restart your local server).

Now in your AIR application, instead of pointing your remoting service to something like “http://localhost/myService” change it to “http://localhost./myService” and you should see your remoting calls coming up in Charles. Happy days!
