Keycodes not getting identified and throws error on Android KitKat

Hi There -

I got Google Nexus 5 phone today and tried to test my app on it. Most of the parts work fine but I get following error very frequently. And few parts are not working at all. Any idea what this error means? I searched internet but only found that Google has changed webkit to chromium. Can you provide more details on it or any solution?

I have been talking phonegap (cordova) support and they confirmed it is an issue and I have to log defect here.

11-21 14:49:39.256: E/chromium(5721): [ERROR:aw_autofill_manager_delegate.cc(144)] Not implemented reached in virtual void android_webview::AwAutofillManagerDelegate::UpdateAutofillPopupDataListValues(const std::vector >&, const std::vector >&)

I have a custom method created by me for converting user entered values to currency format. And the above problem is happening all the time when I press delete button from keypad.

Here is the code:

function CurrencyFormatter(object, e, maxLength)
{ try { //alert(e.keyCode); var val = $.trim(object.value); var len = val.length + 1; var char = String.fromCharCode(e.keyCode);
var pattern = new RegExp(/^[0-9]+$/);
//console.log("char: " + char);
//console.log(pattern.test(char));

//console.log(pattern.test(new String(char)));

if(len <= maxLength && pattern.test(char))
{
//console.log(val);
if(val == '0')

{ if (val.length > 0 && val.length < 11) val = val + char; }

else
if (val.length < 11)
val = val + char;

object.value = formatCurrency(val, "add");
}
else if(e.keyCode == 8)
{
//var numBox = document.getElementById('numBox');
if(val.length > 0)

{ //pennies = pennies.substring(0, pennies.length - 1); object.value = formatCurrency(val, "del"); }

}

e.preventDefault();
return false;
}
catch (ex)
{
console.log(ex);
}
}

function formatCurrency(amount, type)
{ var i = parseFloat(amount); var i2; //console.log("1: " + i); if(isNaN)

{ i = 0.00; }

if(type == "add")
{
i = Math.round(i * 1000);
//console.log("1.5: " + i);
i = i / 100;
//console.log("3: " + i);
}
else if(type == "del")
{
i = parseInt(i * 100);
//console.log("2: " + i);
sub = new String;
//console.log("sub1: " + sub);
sub = sub.substring(0, sub.length - 1) ;
sub = sub == ""? 0:sub;
//console.log("sub2: " + sub);
i = parseFloat(sub);
//console.log("del: " + i);
i = i / 100;
//console.log("3: " + i);
}

s = new String;
if(s.indexOf('.') < 0)

{ s += '.00'; }

if(s.indexOf('.') == (s.length - 2))

{ s += '0'; }

//console.log("4: " + s);
return s;
}

The crash errors will not be on phone screen.

The sample I have provided should work to enter just numbers and format it to currency. No special characters should be allowed.

If you can enter special characters then the issue is there.

Heres what my app is running on:
Cordova - 2.0.0
Jquery Mobile - 1.0
Android - 4.4 (Kit kat)
Device - Nexus 5

Will be waiting for your reply on this as we can't certify our app on Android 4.4
