Cross-domain requests using PhoneGap and jQuery doesn't work
you need to whitelist your external domains. just go to your phonegap / cordova plist file in xcode and add a new entry, have it's value be * and you can access any website out there.
also know that this WILL NOT WORK IN A BROWSER. Browsers have crossdomain issues, not phonegap or mobile devices.
I solved the problem by myself. The problem is located in the url, where I have to add a domain. I changed
var url = "http://remote/server/rest/call";
to
var url = "http://remote.mydomain.com/server/rest/call";
and it works!
I assumed the first url should work because it works on an iphone app with exact the same url and settings. It has also something to do with a double firewall(Windows and ESET firewall) where I shut down the Windows firewall.
Anyway, thanks for your answers!
Adding this to the config.xml saved me
<gap:plugin name="com.indigoway.cordova.whitelist.whitelistplugin" version="1.1.1" /><access origin="*" /><allow-navigation href="*" /><allow-intent href="*" />
I was baffled as to why any outside resource did not load, even google maps and my remote debugging tool. This saved me!
