Subject [jira] [Created] (CB-2282) HTML5 Application Cache is not enabled
Date Tue, 22 Jan 2013 12:36:13 GMT
Rudolf Kuczi created CB-2282:
--------------------------------

             Summary: HTML5 Application Cache is not enabled
                 Key: CB-2282
                 URL: https://issues.apache.org/jira/browse/CB-2282
             Project: Apache Cordova
          Issue Type: Bug
          Components: Android
    Affects Versions: 2.3.0, 2.2.0
         Environment: Tested on LG Optimus 2x (LG-P990) with Android 4.0.4 physical device
and on Android 4.0.3 x86 virtual device.
Tested PhoneGap versions: 2.2.0, 2.3.0
            Reporter: Rudolf Kuczi
            Assignee: Joe Bowser



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);
    
});
