Ext.device.Geolocation and Ext.util.Geolocation

Hi

In my app im trying to watch the current position of the user .. so i have tried the watchPosition of Ext.device.Geolocation, but it's seem that the watchPosition don't fetch for the coordinate.

And with Ext.util.Geolocation, i can get the current location but can't watch it.

I need to work with "Ext.util.Geolocation" for the web version and "Ext.device.Geolocation" for the android app for better accuracy.

How can i implement it in the correct way ?

BRGD,

NB: i use S.T 2.3.1 and Cordova 3.3.0 and i build for android 4.3
