I'm trying to understand the way android handles my application cache data....Some times i'll go in there and the cache directory is 6-7mb. What type of data is stored there? Is there a way in the mainifest I can say don't use cache or clear cache at Xmb ?

I'm fairly new in Android/Java programming, so some of the basic stuff is still quite confusing. So, lets say my application gets all data (articles) it requires from external XML files, it parses them to data models (Article class) and those articles will be used (displaying in lists or single article) all over the application for all it's lifecycle.
Where should I keep them? Can I create singleton class with an array containing all the articles I've parsed? Or should I save them to database and then query it on demand? (that sounds like too much work, I don't need to cache them for now) What's the best practice here?
We are supposed to cache textual and audio data in our application until device is booted or maximum of two days, whichever happens earlier. To get a perspective on data to be cached, note that we are to store about 200 text headers containing around 10 fields, each of length 30 bytes and about 20 sound files each about a minute long.We are getting the textual data by parsing XMLs and then we keep them in ArrayLists. The sound files are directly written inside the app storage using File I/O (and not on SDcard or Apps Cache directory).This application is to be run on devices running Android 1.5 or later.I understand, and please correct me if I am wrong, that we can cache the files either on SDcard or inside the application or inside applications Cache directory.
View 2 Replies View RelatedI 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?
View 3 Replies View RelatedI have creating application with 3 activities, where A - list of categories, B - list of items, C - single item. Data displayed in B and C is parsed from online XML. But, if I go trough A -> B1 -> C, then back to A and then back to B1 I would like to have it's data cached somewhere so I wouldn't have to request XML again.I'm new to Android and Java programming, I've googled a lot and still can't find (or simply do not have an idea where to look) a way to do what I want.Would storing all received data in main activity A (HashMaps? ContentProviders?) and then passing to B and C (if they get same request that was before) be a good idea?
View 3 Replies View RelatedI'm making an Android Java app game (although this question applies to all languages really) and hope to release the first version soon. I'm nervous about how I save data in my game. My problem is that, if in a later update, I decide to store more data or store the same data in a different way, I need to be careful I don't lose or corrupt data for users that upgrade (i.e. I want users to be able to use data created by an old version in the new version, like their high scores from before).For example, say I want to save high scores in version 1.

Does that mean I have to wipe? the cache and data? The two options availabe for wipe in the menu? Also, I place the zip in the root of the memory card, yes?
If I boot into clockwork recovery and clear the cache/data and/or the dalvik cache and then boot back into my rom, will it still work?
I recovered my rom without clearing it beforehand and now all sorts of minor weird things are going wrong. its fine, just annoying.

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.

View 17 Replies View RelatedI'm considering installing a rom and I've heard that doing a data and cache wipe is the proper thing to do to ensure success. What I'm concerned about is how easy it is to restore/re-do all of your settings like ringtones, notification settings, app settings etc. How long does it usually take you to set up your phone again after installing the new rom?
View 1 Replies View RelatedIf you do not root, you could go from 2.0.1 to 2.1 with no wiping of data and cache, it just installs & away you go. Same with 2.1 to 2.2. No wiping of data and cache and all is still there as you left it: apps, settings, preferences, etc. SO, why is it important to do this if you root? What's the difference? And, who said it was important to do? Is there some exact proven logic on why if your rooted you must do this and if not, your somehow fine? That 1 step difference causes a lot of extra work, so I am wondering why this is said to be a must for rooters and non rooters need not do it when they get updates?

HTC Explorer A310e
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?
When downloading a custom rom and the dev says wipe data/cache thats when im in recovery right? I see the options but do i do the data first and will it take me out of there and I gotta go back then wipe the cache? or will it just wipe data and then hit the back button and wipe cache and then hit the back button and hit install from sd?
View 3 Replies View RelatedWell since I've got into installing custom ROMs its nice, but I hate wiping data/cache. I've gone from Nexbeast 1.1 to Nexfro .4 without a wipe. No complaints but when I drop my phone it immediately reboots. When I open it and click stuff to fast it will reboot and sometimes for no reason at all. Is this because of me not wiping data or just sucky phone? Using stock kernel. When going to CM6 should I wipe data?

I made a nandroid backup b4 flashing those roms..so my question is this: Do i have to wipe cache/data before i flash my nandroid backup? Or can i just flash it w/o doing any extra steps?
OK, before I start, it's about an LT15i. I don't know what's happening, but at some .FTFs Flashtool does not show the file list (middle column) and neither "wipe cache" or data and one FTF has the "wipe cache" option only. This is really annoying. Tutorials specify a download link for a specific FTF and after starting Flashtool and selecting the flash option, that FTF is not showing up properly. Should I download an earlier version of the program?

-Turning off Facebook sync (this DID work, but losing functionality that worked just a few days ago kind of sucks).
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?
