Subject [jira] [Commented] (CB-250) [android] app crashes when DNS lookup fails
Date Wed, 15 Feb 2012 11:20:59 GMT

    [ https://issues.apache.org/jira/browse/CB-250?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13208377#comment-13208377
] 

Maciej Jaros commented on CB-250:
---------------------------------

The issue also occurs when you don't have a WiFi (or other connection) active - not sure if
Android throws the same error then (I'm guessing it might be ERROR_CONNECT or ERROR_TIMEOUT).

As for the behavior - I would expect nothing to be loaded or reload - maybe just an alert
could be displayed. If reloading is easier (e.g. WebView already loads the new page when the
error occurs), then that would be acceptable if you ask me.

> If the DNS lookup on a link to loadUrl fails, the app exits.
> Fil traced this to the onReceivedError method in CordovaWebViewClient - the ERROR_HOST_LOOKUP
error code is being passed to that method, which is passed on to the context, and the app
crashes.

> Expected behavior in this case is probably for an error to be reported back to the web
view, and the initial page to be loaded back once more.
