[jira] [Created] (CB-250) [android] app crashes when DNS lookup
fails
[android] app crashes when DNS lookup fails
-------------------------------------------
Key: CB-250
URL: https://issues.apache.org/jira/browse/CB-250
Project: Apache Callback
Issue Type: Bug
Components: Android
Affects Versions: 1.4.0
Reporter: Andrew Lunny
Assignee: Joe Bowser
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.
http://developer.android.com/reference/android/webkit/WebViewClient.html#ERROR_HOST_LOOKUP
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.

[jira] [Commented] (CB-250) [android] app crashes when DNS lookup

---------------------------------
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.

Maciej Jaros commented on CB-250:
---------------------------------
Maybe you could add a function (or event) that could be overwritten/overtaken by an application developer (from JS). The default behavior would be to show a simple alert box (e.g. "The URL is unreachable").
That way if an application developer wants to show their own alert or something else then he will be able do that, but also (by default) the app will not crash and will give some feedback to the user using the app.

[jira] [Updated] (CB-250) [android] app crashes when DNS lookup

Posted by "Joe Bowser (Updated) (JIRA)" <ji...@apache.org>.

Joe Bowser updated CB-250:
--------------------------
Affects Version/s: 1.5.0
Fix Version/s: 1.6.0
This needs to be thought out more. Is an alert OK, or should we just fire an event?
