I have tried to setCredentials and setRemoteCredentials on the RemoteObject but neither seemed to work. When running my app on AIR on the desktop it still prompts me for a user name and password. However on my android handheld AIR does not popup a login screen and automatically throws a fault event. Is there another way to set the credentials so you aren't prompted? I've also tried passing the credentials into the login function on ChannelSet of the RemoteObject.
I encountered exactly the same problem. Did you fix the problem ?
