I have set of images fetched from internet and set it on gridview,here i have option to click here to view more,below the grid view and it fetches images and set it on grid with prevoius set of images,when i exit the application and run it again,the previous set of images remain in cache and grid shows images from cache,here i need to clear my application cache memory,when i exited my application.how can i get it.
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?
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:
This method is called sometime afte a disk writing:
What I'd like to add is the same check on the HashMap size to prevent it will grow too much. Something like this:
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"
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.
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.
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?
Does anyone know how to clear defaults of my own app by code.I know that a user can always go to Manage Applications, find my app and click the button there to clear previously assigned default actions. But for most users this isn't intuitive at all. I would like to offer my customers a solution to clear defaults within my own app if they don't like to use my app as a replacement for a specific action anymore.
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.
Screen mirroring broke on my note 2 with the 4.3 update.
I've read one possible fix was to clear the cache partition (?) But have no idea on a non rooted phone how you would accomplish this. The other alternative is a factory reset but I would need to figure out how to back up my accounts/data to do that.
Using the widget to read stories is draining the memory down on me, has anyone found a way to clear the cache for it? clearing the browser cache doesn't do it, and I have 5mb that's gone from reading the stories.
Browser seems to chew up memory pretty well, which is usually okay, but it would be good to be able to clear it. Well if you long press on the back button you get an option to exit and clear cache. Neat. Any other apps do this?
how to access sd card and clear cache. I am having a problem were I open e-mail w/ attachment and then it ask's if I want to save to the sd card. So I do and now I can not find the attachment, or when I open it it just prompts to save gain.Thank you for any help.
I was rooted and not thinking about using the cache clear app I did it using the recovery menu in the phone. Now I can't see to be able to rename .apk files on the phone. It says the file system is read-only. I have tried remounting the filesystem several times and i can't.
I am dynamically adding ImageViews to a RelativeLayout depending on user input. I have also created a button that when pressed, should clear all of the content of that RelativeLayout (remove all children). I was hoping for a .clear() method, but no such luck.
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.
In Android's settings, in the "Manage Applications" activity when clicking on an app, the data is broken down into Application, Data, and cache. There is also a button to clear the cache. My app caches audio files and I would like the user to be able to clear the cache using this button. How do I store them so they get lumped in with the cache and the user can clear them?
I want to simulate Memory in android programmatically..That is i want to generate an low memory alert when i click on button in my activity..is there any way to do this..? is there any way to limit memory in android..?if u had any ideas.
I own an Android based handset. It keep telling me that its internal memory is low. I've uninstalled many unused 3rd part apps, and restart the device. Its still saying its running low. I guess there are cache's/legacy files remaining somewhere.
I bought a Samsung Galaxy S2 Hercules (T-Mobile) and its used. In the Last week I pull some photos and mistakenly delete them, but with my "Recurva" program i could see all the photos (mine and others owners)
On the one hand I'm happy for having recovered, but if one day I want to permanently delete photos, I have the fear that the other person recovers.
How I can delete all photos, videos and files in the cache memory?
