Ext.util.jsonp request does not work on device android 2.3 / iphone 5.1

**briantes** · 2 Apr 2012 4:02 AM

Hello. I have a simple application that requets data to a server using ext.util.jsonp.
My server is made with Embarcadero Delphi 2010, and runs on local network over port 81.
If I use google chrome to run the application, it works good and ext.util.jsonp request gets information from server. I use for the url: "http://192.168.0.10:81"

But if I try it with iphone or android device on the same network, it does not work. For iphone I have put the files on a public server, but with android I have made an apk with eclipse and phonegap, and install it on the device.

I use jsonp to avoid cross-domain problem, as said in documentation.

No error is reported, but ext.util.jsonp does not connect neither run the callback function.

Any suggestion?
Thanks.

You should use a remote debugger to see if there are any errors. Also would look at server logs to see if the server was hit and with what params.

Yes, the first thing I did was activate debug on safari (on iphone), but no errors reported in my phone. It doesn't call "callback" function. I put index.html the code here:

Code:

<!DOCTYPE HTML>
<html>
  <head>	
	<title>Test jsonp</title>		
	<link rel="stylesheet" href="sencha-touch.css" type="text/css" >
	<script type="text/javascript" charset="utf-8" src="sencha-touch.js"></script>
	<script >
Ext.regApplication({
	name: 'testJsonp',   
	launch: function() {
                var temporizador = setInterval(function(){    	
                	alert('requesting...');
            		Ext.util.JSONP.request({
            			url: 'http://192.168.0.10:81',
            			callbackKey: 'callback',
            			callback: function(result) {
            				alert('receive');
            			}
            		});
                },3000);	
                }
            });
		</script>			
  </head>
  <body >
  </body>
</html>

If I test It with Google Chrome, all message are shown and works good.
With my iphone 4G (ios 5.1), and with my arnova 7b G2 (android 2.3), only alert message "requesting..." is shown. No errors in safari debug on iphone.
As you can see, a local ip is used. The PC in this computer runs a http server that works good because with google chrome (on the same pc but with network ip) works good.
Thanks for your help.

Is there a solution for this problem? Even I have run into the same issue. Infact twitter app also does not work when you bundle it as an apk and deploy on Android emulator.
