Application cache does not work on Android device (works well in Chrome browser)

Question

I am trying to use the application cache to validate performance.

I was guided on different sites. (e.g. http://xguru.net/621 ...)

create a cache.man file, set the mime type as text / cache-manifest.

The problem is that...

It works well in Chrome Chrome browser, but does not work on my Android phone.

I tested ICS and Gingerbread.

This is a manifest file.

CACHE MANIFEST # manifest version v0.1 CACHE: ./programs.png ./video.png NETWORK: * 

and then I set my webview as follows.

 getSettings().setAppCacheEnabled(true); getSettings().setDomStorageEnabled(true); getSettings().setPluginsEnabled(true); getSettings().setCacheMode(WebSettings.LOAD_DEFAULT); 

(I changed cacheMode to LOAD_NORMAL, NO_CACHE, but it is no different.)

To see the status of the cache, I use this site. http://jonathanstark.com/blog/2009/09/27/debugging-html-5-offline-application-cache/

 var cacheStatusValues = []; cacheStatusValues[0] = 'uncached'; cacheStatusValues[1] = 'idle'; cacheStatusValues[2] = 'checking'; cacheStatusValues[3] = 'downloading'; cacheStatusValues[4] = 'updateready'; cacheStatusValues[5] = 'obsolete'; var cache = window.applicationCache; cache.addEventListener('cached', logEvent, false); cache.addEventListener('checking', logEvent, false); cache.addEventListener('downloading', logEvent, false); cache.addEventListener('error', logEvent, false); cache.addEventListener('noupdate', logEvent, false); cache.addEventListener('obsolete', logEvent, false); cache.addEventListener('progress', logEvent, false); cache.addEventListener('updateready', logEvent, false); function logEvent(e) { var online, status, type, message; online = (navigator.onLine) ? 'yes' : 'no'; status = cacheStatusValues[cache.status]; type = e.type; message = 'online: ' + online; message+= ', event: ' + type; message+= ', status: ' + status; if (type == 'error' && navigator.onLine) { message+= ' (prolly a syntax error in manifest)'; } console.log(message); } window.applicationCache.addEventListener( 'updateready', function(){ window.applicationCache.swapCache(); console.log('swap cache has been called'); }, false ); 

Finally, this is the magazine that I see on my Android phone.

 [cache Resource] app cache support! [cache Resource] DOWNLOADING [cache Resource] event online: yes, event: checking, status: uncached [cache Resource] event online: yes, event: downloading, status: uncached [cache Resource] event online: yes, event: progress, status: uncached [cache Resource] event online: yes, event: progress, status: uncached [cache Resource] event online: yes, event: error, status: uncached (prolly a syntax error in manifest) 

Images are uploaded, but we get an error in the last line. Therefore, it is always in an inaccessible state.

I assume the problem is with setting up a webview or an Android app. But I can't handle it.

give me advice on using the application cache .. plz ...

Indirectly, the answer related to yugidroid led me to the right line. The blog, which is linked in response, shows what to do:

  String appCachePath = getApplicationContext().getCacheDir().getAbsolutePath(); webView.getSettings().setAppCachePath(appCachePath); 

I deleted these lines again for testing: the same error - readded: no error!
