Hi guys, been using sd maid, to clean cache and it's been amazing but now it's no longer working, possibly due to samsung limiting accessibility access. What app are using to clean useless cache files on your phone please?
1. Cache is not "useless", cache is actually important to the system.
2. Stop using cache cleaning apps, those apps are the real junk to the system and completely useless.
3. When there's a rare necessity to erase cache, do it from the recovery.

Surely when some of the cache files end up taking over a lot of the memory, that can't be right surely?

Are you believing what the app cleaning app is showing the user as junk occupying a lot of space/memory and needing to clean up so that the user ends up using the app and then even pays for it and be in an illusion post cleanup that it's now "cleaner" that didn't require cleaning in the first place?
Temporary files will be created by every app being used, stored in the cache to help running it faster the next time it's launched, would provide a quicker experience overall when the user resumes any work etc. The more often such cache cleaners are used, the more the OS is prevented from giving the user an overall enhanced experienced is what I feel.
And to deal with temporary files that we don't need anymore, duplicate files, large files, Device care>Storage has these options to cleanup.

ok so i searched dalvik cache and I cant find anything... the only thing I know about it is that it takes up space on your phone memory even though your apps are on the sd card... so how do you delete the dalvik cache?...I would need to do this regularly after it takes up a lot of space... I would prefer not to wipe.
dalvik cache is the the stuff that your apps store while you're running it and is pretty vital to the function of your phone. I suspect restarting your phone will clear it, though I have no idea as I use apps2sd and have no need to watch my internal memory. Sorry.
dalvik-cache contains uncompressed (consider an apk a neat lil zip file) versions of the dex files (the exe of dalvik) so that they run on your phone. You delete it, it'll just reindex them on next reboot.
Are you using an apps2sd where your apps are on the sd card or just installing from SD?

umm im using a hero ROM so i believe that my apps are on the sd...is it really worth it to bother deleting my dalvik cache or should I just leave it alone until it gets really big??

Leave it.... If things get buggy then you can rm -r it so the system could start fresh and rebuild anything the could have been damaged. As far as deleting it altogether - like Dude said- not going to happen, system will rebuild it, most likely the same size, may be few bytes off.
Look into your other chaches (browser, market, street, tunewiki, maps, whatever else you're using), this is where you can gain some memory back. Also consider nuking whatever you downloaded, or it came with the rom but you do not use it and have no intention of using it.
Good luck.
every time i do a nandroid and then a titanium restore on my phone with data, it says im low on space. the apps are all on my memory card and not my phone. one of the culprits seems to be the dalvic cache in the root of the phone. i deleted that as a test run and it freed up loads of space. however i ran into alot of force closes. i tried restarting my phone to see if it would restore the data in boot but it then got stuck in a boot loop and wouldnt load into home.
any help over whats the best course of action for things like this?
ive since then done another restore and deiced to only restore the user installed apps (no data) and then go through the ones i need the data restored on. could titanium be installing old data to my phone thats not needed, thus filling up my phone with data from unused apps?
If you are runing on low data space, a possibility would be to move dalvik cache to sd, as you have done with your apps. It will probably slow down a bit your phone, but will will free some space on the phone's internal memory. Look for firerat's all-in-one script and enable the d2x option.

to be honest, i want that to be my last ever option. i like to be able to use my phone at a quicker pace. but may try it later if i cannot find any other options.

You can also move data to sd-card (ddb - option), but for me the performance went down much more than with dc2x. Finding a different solution will be difficult, because dalvik-cache for me has already a size of about 75MB (system apps + gapps + some apps installed). Data for apps are about 30MB. Even with CustomMTD there is not much space left to use, especially when you consider that the performance of the phone will decrease notifically when free internal space goes below 15MB. I am running with dc2x option and I have an acceptable performance. I suggest you to give it a try.
main thing i wanna know is this however. if i have old data on my titanium back ups from apps that are no longer installed. will titanium put that data back on the phone, even if its application/s have been removed from the back up?
decided use the script after all.
thanks for the info AndDiSa
Ok, long story short, I have 113MB of 'system data' in my /datadata folder (66% full), and I want it gone.
But I can't get rid of it... I've tried a full clean install, I've tried manually formatting /datadata from CWM, and I've also tried formatting boot, cache, data, datadata, and system from CWM followed by a fresh install (Kang 12/17).
My wife has the same phone and ROM and she only has 26% full in /datadata. I can't - for the life of me - figure out how to completely clean /datadata.
One thing I noticed in terminal emulator is that the data in /data and /datadata is about equal to what is listed in /system. However, formatting /system did not clear it out.
Please help as this is driving me insane!
Isn't datadata based on your apps? Like dalvik? I think ur wife just has less apps.

I thought so to, but even with no apps (nothing but what comes with the ROM) I have 3x what she has... and she has what comes with the ROM plus all her other apps.
If it does have to do exclusively with the apps, I'm more than willing to do everything step by step to figure out which app(s) cause my issue, but in order to do that I need to be able to clear the folder of everything except what true system data is necessary and start from square 1.
/datadata is apps settings and data. A little more info might help...

What kind of info do you need, and I'll try and supply it. I'm trying to do a clean install so that all of those app settings and data are starting from scratch. Factory resets didn't do it, formatting the folders through CWM didn't do it...
I must be missing something... but I can't figure out what it is.
Some basic background:
Most recently on the 12/17 Kang (CM7.2 RC0) with the glitch v13 (2.6.35.13) kernel and Gapps 08/28
For the just completed testing I only flashed Gapps (08/28) and the 12/17 Kang so I could see if anything I did worked on clearing /datadata.
Other than that, the only modification I've done to my phone is the modem is KG3 i9000.

I haven't... I have the free version currently. Would the pro version do all of this stuff?
The free version should do for deleting data and removing apps.

I'll go out out on a limb here but try backing up your sd card and formatting it?

I had thought of that too... once formatted and I reinstall the ROM and stuff, is it easy enough to just copy those folders back on the phone? That was the one thing I was worried about... and thus I hadn't tried yet.
Formatting always makes me nervous
Are you encountering any issues with it being that full? Or is this just to satisfy your ocd?

As simple as dragging and dropping files. Also nice to start fresh every once in a while to clear out junk from old apps.
I'm getting ready to format my SDcard and start all over... but if I format my SD card, I'll no longer have my ROM zips there to flash. I put the ROMs on my external SD card (emmc), but in CWM I can't mount emmc to make sure they are there to flash when I format my SDCard...
How do I get my ROM flashed again once I format my SD card?
EDIT:
Doing more research it appears that I should be able to format my SD card w/o losing my ROM as long as I leave my boot and system folders alone.
So, if I format /data, /datadata, and /sdcard I should be able to reboot and see if it worked

I am encountering issues with it being that full. I have like 70 apps with approx 38MB of data taken up... combined with the large amount of 'system data' in the /datadata partition I'm running into the issues when that folder gets to 90% capacity.
It's at the point that I can't install new apps that save any data at all or I will have to constantly shuffle which apps can save their data. Doing research I found that the 172MB cap shouldn't be an issue unless you are hording apps... I have a small number of apps with a small amount of data, so things should be better
Thanks for all the suggestions...
But so far nothing has worked.
I formatted the SD card along with data and datadata and rebooted the phone.
My /datadata folder was still listed at 66% full. So formatting nearly everything still couldn't clear this folder.
I'm still boggled why the other captivate started with 8MB system data and I start with 113MB, both on a clean install...
Perhaps my only hope is to clear stuff out again and flash ICS and hope that something is different enough that this 'problem' goes away...
An additional thought
Would I be able to delete the /datadata folder through Root Explorer, reboot into recovery and reflash the ROM?
I would assume the ROM will repartition the phone correctly. System data can't exist in a folder that doesn't exist - right?
Would someone validate my partitioning idea before I spend a bunch of time mucking about trying to make it work?
Some background: I am using a Nexus One with Evervolv/texasice's ICS ROM. The N1 has a small permanent memory, so even with the recommended partitioning, the system partition has only a few MiB free and the data partition is just over 200 MiB. So texasice has a re-written a2sd which has the ability to mount an ext4 partition on the SD card as the data partition (I don't know if this feature is specific to his rewrite or if this is a common thing). It works ok with a Class 10 card, although it's still a little slower than I might like and I get ANRs even for system apps.
With the xdata feature enabled, the >200MB data partition in the memory is wasted space, so I was thinking about re-partitioning to make the system partition most of the 400+ MB of memory and then using Titanium Backup to selectively move apps from the xdata partition to system, with its "Convert to system app" and also integrate the Dalvik cache into the system partition.
Does anyone see a problem with this plan? Will it work? Why have I not seen anyone else talking about doing it?
Thanks!
Wil
My background, in case that helps you gauge your response: I have 15+ years of experience with Linux systems administration & development, including some work with embedded systems, but am still very unfamiliar with the Android userland.
Works fine
So I went ahead and tried it--410 MB for system partition and then I used TitantiumBackup's "Integrate sys Dalvik into ROM" to move the Dalvik cache for system apps into the ROM--it worked fine and things are a bit snappier. I also converted some of my most-used apps to be system apps and get noticeably improved response times. One thing to note is that you should re-run the integration after converting an app to a system app because it doesn't do that automatically.
I am fairly confident that my observation of improvement is accurate, despite the lack of quantitative data and despite the fact that I upgraded the ROM from a2 to a4 at the same time--I ran several of the apps before converting them to system apps and then again afterwards (and after a reboot).

Your experimental is interesting so, if you don't mind, posting your procedures and steps for other members to review. Have you tried to contact Texasice or any developer of your findings?
It just sucks that with most scripts you can't choose which apps you would like to move to sd-ext. I believe timbit made such script for samuaz' MedroidMod, and he would bring out a standalone version, but haven't heard anything about that since Donationgate..
Yep I requested that from Timbit a while ago and new did indicate that he'd consider it.

I want an antivirus or cleaner, to wipe memory (cache, images, trash), but not stay in 2nd plane.
Is there any ?
Check Google's Files Go app.
sd maid and Google’s files go are the only good cleaners.
antivirus apps don’t do crap for your phone.
I only clean cache in settings and 1 once for month in recovery wipe cache
and .thumbnails in file menager
Honestly, Android has gotten pretty good at self maintenance - If you just download from the Playstore, like a good boy or girl, you won't need antivirus. I have used SD Maid also, but honestly, clear your cache under Storage when you get about 2 -3 GBs in, or when apps start to run laggy and you'll be fine.
The days of needing all of the excess stuff like cleaners, antivirus, and task managers are pretty close to over, unless you're installing off grid and have gigs of cached files.
