Simon MacDonald commented on CB-842:
------------------------------------
Okay, first thing is that "navigator.onLine" will always report true when
running from a WebView. Since PhoneGap uses a WebView you will always get true
so you can't count on this navigator property to give you proper network status.
Now, I know that when Android devices transition from 3G to wifi and vice versa
they are offline for a short period of time. We actually wait 500 ms before
sending the offline event so we can check that we are still offline and and a
network connection has not be setup. My advice to you is to do a setTimeout in
your isOfflineAfterOfflineEvent method to wait X number of ms and then check
the value of navigator.network.connection.type to see if it has been updated.

> The event is fired whereas I'm connected to wifi. Putting some logs in
> offline method, I see that navigator.network.connection.type is NONE and
> navigator.onLine is true.
> Ps: it seems it appears after loading a page...
> Right now I've added extra test in offline method to be sure it has been
> called whereas there is really no connection available.
