Description

WRT Github pull request : https://github.com/appcelerator/titanium_mobile/pull/910 When an Android webView attempts to load a non-existent url (for example), no error is fired (as documented!) 
// example: app.js

var win = Ti.UI.createWindow({

backgroundColor:'#fff'

});

var web = Ti.UI.createWebView({

// a clearly incorrect url

url:'http://google.cooom'

});

web.addEventListener('error',function(e){

	Ti.API.info('ERROR: '+JSON.stringify(e));
	alert('ERROR: type:'+e.type+'\nurl:'+e.url);

});

win.add(web);
win.open();

    Testing Notes

    * Run below app.js on *both iOS and Android*. 
       var win = Ti.UI.createWindow({
   	backgroundColor:'#fff'
   });
    
   var web = Ti.UI.createWebView({
   	url:'http://google.cooom' // BAD URL
   });
    
   web.addEventListener('error',function(e){
   	var message = e.message;
   	var code = e.errorCode;
   	if (code == Ti.UI.URL_ERROR_HOST_LOOKUP) {
   		message = "Titanium.UI.URL_ERROR_HOST_LOOKUP - " + message;
   	}
   	var url = e.url;
   	alert("Error url: " + url + "; Error code: " + code + "; Error message: " + message);
    
   });
    
   win.add(web);
   win.open();
    * You should see an alert showing you an error code, the erroring url and the error message. The message and the numeric code value are platform specific, however the code should match the constant Titanium.UI.URL_ERROR_HOST_LOOKUP. If it does match that, the message will begin with a prepended "Titanium.UI.URL_ERROR_HOST_LOOKUP". <-- you should see that at the front of the message. * No sense testing in MobileWeb, that event never fires and anyway a code is not available there. * Run python validate.py -e -s simple -f Titanium/UI/WebView.yml and python docgen.py to make sure there are no errors *related to the WebView documentation*.

    Re-opening as on iOS the error code and error message show undefined. Or should I create a new ticket? [~vijaysingh]
