[jira] [Updated] (CB-2282) HTML5 Application Cache is not enabled

     [ https://issues.apache.org/jira/browse/CB-2282?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Joe Bowser updated CB-2282:
---------------------------

    Description: 
By default HTML5 Application Cache is disabled when instantiating a WebView on Android: http://developer.android.com/reference/android/webkit/WebSettings.html#setAppCacheEnabled(boolean)

PhoneGap app container also instantiate WebView with AppCache disabled.

I've modified DroidGap.java to call .setAppCacheEnabled(true) and now the AppCache works within PhoneGap and the following javascript receives AppCache event.

Event log sample:

01-22 11:37:43.947: D/CordovaLog(6111): checking
01-22 11:37:43.947: D/CordovaLog(6111): noupdate


How to reproduce:

With cache disabled no events fired by the following javascript code:

   function logEvent(event) {
        console.log(event.type);
    }

    window.applicationCache.addEventListener('checking', logEvent, false);
    window.applicationCache.addEventListener('noupdate', logEvent, false);
    window.applicationCache.addEventListener('downloading', logEvent, false);
    window.applicationCache.addEventListener('progress', logEvent, false);
    window.applicationCache.addEventListener('cached', logEvent, false);
    window.applicationCache.addEventListener('updateready', logEvent, false);
    window.applicationCache.addEventListener('obsolete', logEvent, false);
    window.applicationCache.addEventListener('error', logEvent, false);
    
});
