Subject [jira] [Commented] (CB-842) Offline event fired without special reasons
Date Mon, 04 Jun 2012 16:59:22 GMT

    [ https://issues.apache.org/jira/browse/CB-842?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13288673#comment-13288673

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.
