Android :: Will WebView Cache Persist Between Application Runs?

Mar 16, 2010

I have a WebView. I'm not quite sure how caching works for it. Ideally I'd like to load a web page from the network once (images included), then from then on only ever load it from the local cache. I'm not sure if we have this level of control over webview. Will it at some point just auto-clear the cache? How could I tell? I need to be sure that it's really keeping the page cached between different runs of my application.http://developer.android.com/reference/android/webkit/WebSettings.html.

Android :: Loading Cache When Offline In Android Webview

Sep 24, 2010

i have an application which loads urls from a website. Now i want that the aplication uses the cache when offline. But i just get the failure site which says that im not connected to the website. At first i set the Cachmode to Load_Normal but this doesnt help. Next i tried a realy "silly" approach using the ConnectivityManager:

cm = (ConnectivityManager) this.getSystemService(Activity.CONNECTIVITY_SERVICE);

if(cm.getActiveNetworkInfo().isConnected()){
mfnWebView.getSettings().setCacheMode(WebSettings.LOAD_DEFAULT);
mfnWebView.loadUrl(url);
}
else{
mfnWebView.getSettings().setCacheMod e(WebSettings.LOAD_CACHE_ELSE_NETWORK);
mfnWebView.loadUrl(url);
}

but this just leads to crashing the application. Is there a simple way to load the cache when offline and existing. And just if not existing showing the failure message.

In cm roms, dalvik cache of system apps are generated in /cache but those data/apps are generated in /data. Is there any way to disable this behaviour? Cache partition in our phones is too small. In AOSP and AOKP and stock roms, dalvik cache is always generated in /data no matter whether its a system app. any way to achieve this in cm roms?

Android :: Android - Image Cache Stategy And Memory Cache Size

Jun 21, 2010

I'm implementing an image cache system for caching downloaded image.

My strategy is based upon two-level cache:
Memory-level and disk-level.

My class is very similar to the class used in the droidfu project

My downloaded images are put into an hashmap and the Bitmap objet is wrapped inside a SoftRererence object.

Also every image is saved permanently to the disk.
If a requested image is not found into the Hashmap<String,SoftReference<Bitmap>> it will be searched on the disk, readed, and then pushed back into the hashmap. Otherwise the image will be downloaded from the network.

Since I store the images into the phisical device momery, I have added a check for preserve the device space and stay under a 1M of occupied space:

CODE:.................

This method is called sometime afte a disk writing:

CODE:..............

What I'd like to add is the same check on the HashMap size to prevent it will grow too much. Something like this:

CODE:.....................

My question is:
What could be a right MAX_MEMORY_SIZE value? Also, Is it a good approach? A good answer also could be: "Don't do it! SoftReference is already enough"

Android :: Return Value Of Get Drawing Cache

Jun 17, 2009

From the JavaDoc, it said it returns 'a bitmap representing this view or null if cache is disabled'. My question is what if the View is longer than the phone screen (you need to scroll vertically), what does the bitmap return? * only the visible portion of the view * everything the view has (both visible + invisible part)

Android :: Cache Supposed To Be Accessible?

But apparently it is not accessible, (a FileNotFoundException is thrown).

Android :: Pragma - No-cache Not Supported?

Sep 3, 2010

I work on an application to display a remote page in a webview. The page contains a simple input form and an image. The image is updated automatically by server using specific header. The page is never displayed.

Searching on the web to find a way to resolve this issue.

I read this : http://remotedroid.net/blog/2009/11/13/android-browser-caching/ "Pragma: no-cache, and all the other server-side headers also have no effect as far as I can tell."

Do you have a work around ?

Android :: Cant Clear Cache On Some Apps

Apr 27, 2010

I have a couple apps I have noticed when I open a file it must cache the file internally, but gives me no way to clear. For example Zumodrive and repligo reader both will show 20+mb in my settings, but clear cache is greyed out and shows 0mb. However when I delete these apps and reinstall them, I get all that internal memory back. I am running a rooted Nexus One.

Android :: Counting Files In A Cache

Nov 3, 2010

I'm trying to manage the files that I store in a local cache. I download files, then delete them after the total file size in the cache exceeds a certain number of bytes. What I'm shooting for right now is something simple: setting the max cache size to be 1 MB, or 1*1024*1024 bytes = 1048576 bytes. I have a method that gets the cache directory, then does a listFiles() on that File to get all children of the directory. I have a flat cache structure, no subdirectories, so simply calling f.length() on every child should give me my total cache size right?

Well what I'm finding is that the amount I count is about 0.9 of size reported in Manage Applications > Application Info for my app, in the Cache section.

Am I making a bad assumption that File.length() will actually return to me the size, in bytes, of a file on disk? I also wonder also if disk space in the Cache directory is being used by Android at all for some reason I'm unaware of.

Android :: XML Parsing Slow - Cache

Aug 16, 2010

I have seen that xml parsing is very slow. Using sax would be better, but benchmark show that sax work only 30% faster as dom. Is right? Is faster if I construct a "DOM" using sax?

To reduce time i like to cache xml file. Caching it as xml is not a good idea because the parsing time is there again the secondo time.

Should I use sqllite? Is faster? Is an idea to use an ObjectOutputStream? Can I put in asset a file maked by ObjectOutputStream or the serialized objects can be different in different mobile hardware?

Android :: Slacker Radio Cache?

Jan 22, 2010

Coming from a Blackberry Storm, I had Slacker Radio and it was one of the first apps I downloaded on my new Eris yesterday. However, I am finding that the ability to cache radio stations to your media card is missing from the features of the Android app. The cache was extremely useful as it wouldn't force the data connection and thus helped to conserve battery life.

Is there an alternative app for radio that will cache stations or do I need to hit up the Slacker team to get an update to the Android App?

Android : Way To Control An App's Cache Size?

Aug 10, 2010

My app has a WebView which displays Google maps. I'm trying to limit the cache size to a reasonable one - like 2MB. After checking with settings->applications->manage applications I found out that regular page load gets the cache to 900kb. And dispite my efforts, I can't limit the cache size or monitor when the cache limit is being reached. If I'm playing with the map on the webview, the app can even reach 10MB and no "ache max size reached" message is received.

Android : Way To Clear Cache On All Apps?

Feb 14, 2010

I searched and found many posts regarding clearing cache. But didn't find this answer. Is there a way to clear cache on all apps at once? I went through the settings/applications/manage apps, and checked and cleared cache on many, but this is real tedious, but seemed to give great results. Phone feels much faster. (NOT ROOTED) Psychological? Dunno, but question still stands, does anyone know an easy way to do this? Additionally, is there any risk of clearing cache from any apps?

Android : How Can I Manage Cache Of MapView?

Feb 1, 2010

I've made an application based on the Google Maps API. The problem is that my application is made to be used in the wild, in places where there is no network. So I would like to manage the cache in order to ensure that specific tiles are saved and available during the trip (I'd like to redirect them in database but any method may do). For now, I didn't found any other method (not tested) than try to recode the MapView class. I'm focusing on Google API in order to have satellite photography (for places where there are no roads). What could I do ?

Android : Cache Data In Droid?

Jan 5, 2010

I have an ArrayList of custom, simple Serializable objects I would like to cache to disk and read on re-launch. My data is very small, about 25 objects and at most 5 lists so I think SQLite would be overkill. In the iPhone world I would use NSKeyedArchiver and NSKeyedUnarchiver which works great. On Android I've attempted to do this with with a FileOutputStream and ObjectOutputStream and while the result is the same, the performance is terrible. Is there a better (read faster) way to cache small objects to the file system in Android?
