Android :: Programmatically Clear Browser Cache - History

Sep 22, 2010

During my activity I'm sending an intent to the browser in order to display a webpage :

Intent i = new Intent(Intent.ACTION_VIEW, Uri.parse("http://ww.mywebpage.com"); startActivity(i);

I need to make sure that before sending the intent the browser cache and history are cleared so that the page get loaded from server directly and not from phone.

So far I've found the 2 following but I'm not sure they are used correctly :

Browser.clearHistory(getContentResolver());
Browser.clearSearches(getContentResolver());

Also with that cache is not cleared.

HTC Desire :: Where To Get Cache Clear Application?

Apr 27, 2010

We've had our desire's for a few weeks now and was just wondering what the phones performance is like for you guys/gals? you've all put on apps that you want and music and videos etc., has this affected the phone in anyway? Does it still run like it did out of the box or do you experience lag or other faults? Interested what you have to say.

The only gripe that I have is it is sometimes slow to access the market and takes a few seconds to load the page when scrolling down and I've got a stutter when I access an app to read reviews. Other than that it still runs smooth, I've got music, videos, apps, widgets and voice to text on mine and is easily the best phone I've ever had. Has anybody got a cache cleaner app, I can only find one for rooted phones?

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 :: 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.

HTC Incredible : Need To Clear SD Card Cache

Oct 24, 2010

so I was jokin around with my friend at a bar and we started looking up naughty pictures with a free pron program that I found on the market. We were comparing the people in the bar to the people in the photos and we found some hilarious matches. Anyway, that was last Thursday. Now I see that the pictures that were pulled up on my phone are now easily viewable by merely trying to attach a picture to a text message or an email. Basically, if anyone looks at my phone and tries to see my pictures or something they will see these stupid pictures. The phone says these pictures are saved in the SD Card Cache. How can I clear this cache? I've unmounted the card, twice. No go. I've uninstalled the horrible program (it was free and you get what you pay for, I guess). I needs me some help! I've been perusing the interwebs looking for help and this forum seemed like the most active place right now.

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 :: Android - Orientation Change - Exits Application But Without Crashing

Sep 2, 2010

I have two layouts: layout-port and layout-land. If I run the app with emulator or device, either vertically or horizontally, the app runs fine with the correct layouts. However, if I rotate either the emulator or device, the app exits. There's no crashing, perse', it just exits. I have other app's with similarly defined layouts that work fine without any orientation handling in the manifest. I'm not concerned about persisting data.

The main differences between the one's that work and this one are (this one has):

* Menus with sub-menus
* Dialog screens (not the android dialog widget)
* Tab widget

All of the above items work in their respective layouts (port and land), the app just exits when rotating the emulator or device and I need to restart the app.

Sprint HTC Hero :: Caller ID Lookup Broken - Need To Clear Cache

May 10, 2010

I just switched my contacts from Outlook to Gmail. No problem in doing that. I left the outlook contacts on the phone (just in case), but switched the View item in people to only show the gmail contacts. Whenever I make or receive a call now, the caller ID lookup always tells me I'm calling or receiving a call from one particular user, who is not the caller/callee. Clearly I need to clear a lookup cache, but which one? There are the following caches/data that might need to be cleared: Contacts Storage, Gmail Storage, People.

Android :: Clear Maps History Programmatically?

Nov 19, 2010

I want to programmatically clear the history of the android maps (and navigation) application.

I know there is a way to clear the browser history via Browser.clearSearches(getContentResolver());

And the corresponding permission: com.android.browser.permission.WRITE_HISTORY_BOOKMARKS
and this works fine (2.2.).

I couldn't find any way to clear the Maps-History though. Clearing the google/history online doesn't help either.

There are some apps in the market that promote to do that, so there must be an API for it, but i really couldn't find it yet.

I also messed around a bit with CLEAR_APP_CACHE and CLEAR_APP_USER_DATA but seems like they are signed/root-only permissions and delte too much anyways.

Android : Browser Cache - Previous History In Order To Save Internal Phone Memory

Nov 28, 2008

There are a couple of options within the browser I didn't find until after searching for it, so I thought I would share it with the rest of the community in order to help out.

-Everyone should clear the browser cache and previous history in order to save internal phone memory. To do this go to BROWSER press the MENU button and press MORE. There should be a list of things in there but what you should be interested in is the last item which is SETTINGS. From there in privacy settings there will be options to clear both cache and history.

- Another little tip I wanted to share was viewing webpages in landscape mode without opening your keyboard. To do this simply press the MENU button from within the BROWSER and go down to FLIP ORIENTATION. You should realize tho by doing this you browser will continue to be in landscape the next time it's used. In order to return it to it's normal portrait mode just follow these steps once again.

-There are a number of other things you can mess around with or find with the MENU button within the browser so just take a look at it yourself even if you don't want to do any of these tips.

Android :: Will WebView Cache Persist Between Application Runs?

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.

I have like 2 friends on google+, 3 posts, and can not for the life of me figure out what in the world all that data is.

I'm going to remove the data , freeze the app, but just wanted to know if noticed a disproportionate amount of data in the Google+ app compared to the amount of activity/usage I have on google+.
