Dalvik Cache (Galaxy S and others)tdal - Galaxy S I9000 Android Development

Sorry I'm a little bit new to this so if this thread should be removed then feel free.
I've been reading a lot of information on why a Samsung Galaxy S (and a few others) slow down after long term use (typically 3-4 weeks without reset). I know all about the RFS file system and it eventually becoming more and more corrupt resulting in slower operation.
Another thing I have noticed is that a good few users claim that such things as the Dalvik cache etc slow the device. If you hard reset the phone then the cache is cleared and things seem faster. If this is true, why use a cache? Surely you would create a cache in order to speed things up.
Also, if this isnt the case then what DOES eventually slow the phone. I have had two Android devices and they all seems to become a lot slower a few weeks down the line than after a reset. I do not really install/uninstall apps, I install a few on first hard reset and pretty much leave it.
Cheers and what an awesome forum, some serious talent here. Pitty Samsung couldn't pay you something to fix their firmwares.

Just dropping by to comment on the dalvik-cache.
It shouldn't be cleared. Theres no point because it holds the .dex's for all ur apks. If u wipe dalvik-cache system will just recreate it. If u want more space on /data, odex ur build.

Hey, don't worry I'm no noob to Android. I'm rooted, voodoo'd and all the rest. I also develop for Android although not at the OS level which is why I'm here, to learn.
I'm no Samsung fanboy either, check facebook.com/SamsungUK/posts/1714342428736141.

An experiment...

So we've got root access. Awesome. Everyone has been looking forward to installing apps to their SD card as well as other neat tricks.
Well, I haven't.
I hate to be the buzz killer but there is a fundamental flaw with the way apps are installed and uninstalled that means even moving them to a spacious SD card is not solving the problem.
Before I go rooting the phone and hacking as a way to eliminate some of the more annoying problems with Android, we need to first distinguish between bugs, technical limitations and poor implementation. Not allowing installs to the SD card out of the box is a technical limitation...Apps2sd creates a Linux partition on your SD but it's not ideal.
But that's neither here nor there. I'm not here to discuss the reletive merits of rooting or using apps2sd. What I want is the underlying code to work properly before I go hacking. It doesn't matter if we only have 100mb of space or 2GB for apps. If I install a 2mb app and them remove it I want the WHOLE 2mb back.
This morning news of the pre release alpha of Fennec (mobile Firefox) was announced. I attempted to install it but there was only 25mb of space on my phone. Apparently this is a BIG install and needed about 39mb. Anyway long story short, it didn't work. No matter how much space I cleared (up to 40.89mb at one point) it still told me I didn't have enough space.
So now I have a phone with 40mb of space and I had to clear out some unused apps to get there...I also cleared out my IM app, Nimbuzz, which I DO use. So I figure I'd install it again...but I'm thinking, it was big! Over 4mb installed. I figure I'll look for a smaller lighter app. I try Meego. Nice, small, but no Skype chat. So I uninstall and try Fring. Nice, has Skype...but no Facebook. The only one with the features I want is Nimbuzz. So I uninstall Fring. Two apps installed. Two apps removed. I look at my space. 35mb.
5mb has seemingly vanished into nothing!!! Meego was only about 500kb. Fring about 1.5mb. Where did all that space go?!?
I reset and there's no difference.
So to my experiment. I needed to verify the space suck bug.
Reset phone. I'm starting with 39.89mb.
Install Robo Defence Free. It's advertised as 1.25mb.
Reset phone. 38.02mb. I've used up 1.87mb with that install. According to App Manager Robo Defence is using up 1.41mb.
Uninstall Robo Defence. 38.18mb. Restart. final = 39.42mb.
In just one app install and removal, I've lost 0.47mb
Why? What has used that space?
Despite having 40mb of space this morning when attempting to install Fennec, I have since removed Nimbuzz, Shopper, Robo Defence, Poker, Layar, and Google Translate and I've not gotten back up to 40mb.
Can someone tell me what the hell is going on?
Yeah this is a major worry.
I hope someone can get to the bottom of it...
Try going to settings - applications - manage applications then hit menu and choose sort by size. This should show you the biggest space hog. My guess is that the browser and/or market caches are getting big as you're browsing for these apps. You can press on market and there will be a button to clear the cache, same for internet.
Hope this helps
Nope, that didn't even dent it. This is a real bother.
Have you tried to delete the cache and the data of the application before uninstalling it ?
Under settings/applications/manage applications when you choose an app you can see the size of the application but also the size of the data and the size of the cache. Maybe uninstalling an app don't remove at least the data and/or cache...
Guy's, honestly... You are looking far to deep into this and the word "control freak" comes to mind..
Enjoy your phone and dont quibble over 0.47MB when you have 32gb to play with. A massive thanks to Paul for getting us this root in the first place, we now have options to do anything we want with the phone.
Worry if your phone cannot be used, yes
But worring over small, irrelivant problems will just lower your enjoyment of this beast! Take a chill pill and enjoy that wee can now install apps on the sd card and are not limited to space
Cheers Paul))))

What about those of us who don't plan to root? I think the OP's point here was that this is an issue and rooting isn't really a solution for a lot of people.
Why would you not root? I dont see why you would not open your phone up to obvious advantages and extra app's, especially when these apps have the potential to extend battery life and volume levels, two of which we know with the Desire are pretty dire.
JD
Perfect volume and 2 days battery here mate
I'd only root for A2SD, but might see if Google sort it themselves first as I don't use a lot of apps anyway - it's just a phone after all

First installing to SD slows down your apps noticeably. It's not ideal. It's the best solution we have RIGHT NOW, but don't mistake that for being a good thing.
I'm not quibbling over 0.45mb. If you reread I LOST 5mb! That's enough space for a few apps, no?
My point being that up until now this clear bug (losing data that doesn't seem to be associated with an app so is therefore not counted in it's cache and is not cleared) has been ignored by throwing SD space at it. That's foolish.
Well i get just over 1.5 days battery life and volume is not too bad for me, but i would like the music volume to be louder Also the main thin gthe root would mean for me is that i could get the Nexus rom on to my Desire and hopefully get a quick update to Froyo Because lets face it, how long are we going to wait for HTC to update sense???
JD
Don't like stock Android - I'm happy with Sense!
But enough thread hijacking!!
So you will be happy to wait 6 months for HTC to update Sense to intergrate with Froyo? (based on past updates, eg.. Hero, which is still on 1.6)?? I can understand your point, but sense for me is just a waste of screen space
The only reason i bought the desire was because of the slightly more RAM and actual buttons instead of touchscreen buttons Sense isnt a real big must for me
JD
Well, yeah! The Desire as it is does exactly what I want it to out the box. I had to cook my own ROM for my HD2 to get it working as I want but this just works!!
I prefer the eye candy of Sense, stock Android is boring and I hate using garish themes...if I feel the need to root it I will but as it is I have no need to
Very true mate Well i hope they have a frozen youghut ready for you apon release
JD
Guys, take it somewhere else eh.

same here. I've two Desire, installed exactly the same apps and had a difference of 12 mb afterwards. I tried to delete every cache a.s.o, still a difference of 5 mb.. reboot .. nothing changed. Next day -> reboot again -> 2 mb difference? No clue what's exactly going on with the rom.
@sense: I bought the desire cause i thought it can't be worse than the nexus one cause if i don't like sense, just install launcher2 and deactivate it. What i did not know: HTC just removed some stock android applications and integrated their crappy apps, and in addition they implement some features i want to REMOVE, i do not want to see them anymore (f.e. flickr.. why flickr? this is android/google, i want a picasa button!, tweet, stocks a.s.o... no uninstall option).
I need root to get rid of the things i don´t like.
I did say sorry for it - he's the one coming back at me!!
I'll leave it now mate, my 2p though, I personally don't care about the memory - if it gets to a point when I do I'll hard reset and start again. Probably just needs the Android equivalent of a defrag!!
Have done two hard resets (not for this reason) and my memory was lower after each - something to do with the re-installing of the apps I surmise?

That's strange. After a hard reset it should have exactly the same memory each time. After all, that's the whole point of a hard reset.
And I must say that the issue raised by OP is very worrying. Installing and then uninstalling applications should give you back the exact same memory as you had before. I can accept residual files on the SD card, but the precious space on the internal flash should definately be fully reclaimed after an uninstall.
If not, there is a fundamental flaw somewhere. If anyone can shed more light on this issue, please do so!

[Q] Have question after root

I finally got the nerve up to root. Wow simple thanks to all the advice here at XDA.
Now, the question, and yes some what of a noob , but hey, I rooted, with no questions. LOL
I was under the impression that the Sprint bloatware, when removed with Titanium would free up storage (internal).
I have deleted , football, kindle and a couple others and have not seen any change.
And also what is safe to remove. I followed a link and it showed about 8 progs.
Thanks to all, I am a real good computer hacker. going back to the 90's, but for some reason get nervous doing the phones.
BTW love my EVO
had g-1 and nexus 1
It should show for internal however the apps you are removing might not be that big.
You can remove sprint TV, voicemail, football, nascar, (sense), radio, sprint app updater, Nova, Amazon mp3, stocks,all corresponding Widgets, basically everything sprint puts on the phone. One thing to remember is you need peep if you sync Facebook otherwise you will constant sync.
Thanks for the reply. How about you tube?
You could also flash a different ROM. I know from reading that there are close to stock ROMs that have all of the bloatware removed & even in some cases, Sense, but they're still Sense-based ROMs. I stuck with stock for a while, but finally switched to Cyanogenmod & was amazed at the amount of free ram compared to stock. I'm not sure about internal storage, but I don't move any apps to the SD (even though I could move all of them, minus widgets, if I wanted) and I have a ton of apps downloaded with ~250mb left in internal storage. I'm not sure how this compares to you, or if you'd want to change ROMs, but I suggest making that jump.
Edit: YouTube is safe to remove. You should, however, freeze them instead of uninstalling if you want to stay on stock & potentially accept an ota update in the future. If you've already removed some, then go ahead and remove them all.
Thanks, I plan I flashing in the near future. But damn, there are so many to choose from. It does seem CM is popular. Right now (one step at a time) just getting rid of bloat and duplicates.

I guess what I'm saying is, if you plan to flash anyway (at least in the near future), removing bloat is redundant. Custom ROMs don't have bloat installed anyway. I know it sounds like a daunting task, but with the right amount of general technological knowledge/experience you'll do just fine. I was nervous too but after my first flash, I switched recoveries (I prefer Amon Ra over CWM), flashed a custom font and a theme within a week.
Just be sure to make a backup, and if you don't like it or something goes wrong you can just switch back & you'll be right where you left off.
But if you're not ready or you don't want to, that's perfectly fine. If you need someone to guide you through it & help you with the step by step, feel free to pm me when you're ready. There are plenty of other members here that will do the same.

I was once a newbie, just to let you know out of all the roms. CM has been the best, super fast great battery life. and the best of all now it has 4G. Before it didnt however CM7 RC2 now supports it.
Flashing a new rom is super easy just reboot the phone into recovery, (holding down the power button and vol down button on boot) make sure you have your rom zip file on the SD and flash it. DONE reboot and enjoy.
You can backup your text messages but i dont because its just more stuff to reload on the phone
In other words JUST DO IT!! I've never looked back since i started to flash my phone. and i hope you dont either.
Ya like the guy said above , freeze the apps dont delete them. And as far as a rom goes i would recommend the Destroyed Gingerbread Rom.. it owns!!!

This is news to me. Can you or someone elaborate on this? I removed Peep a long time ago and I haven't noticed any issues with Facebook.
Finally got the nerve, CM is on. Gotta go play, get back later with my experience of it.
Thanks for the encouragement to all, so simple. Ha ha
It doesn't matter quite as much now that you're on CM, but just FYI, deleting apps that came with the stock ROM (or any rom for that matter) usually doesn't give you more space to install other apps -- at least not directly. Your phone has different partitions. Apps you install go to /data. Apps that come with the rom are in /system. Deleting from /system doesn't give you any more in /data.
You will save a little space on /data because it won't store the dalvik cache of that app (at least it will if you remove it. I'm not sure if freezing keeps it from caching the dex).

[q] what is journaling?

can someone please explain to me what journaling means? what it does? and if needed how do i get it? im new to this and want to start flashing roms but im trying to collect as much info before i actually do something. thanks

I am going to be nice and answer your question after 2 words 1)search and 2)Google
Journalling is when the phone writes all things back to the phone twice so that it verifies everything. Then if you drop your phone and the battery pops out and it corrupts your data, there is a non-corrupted version still on your phone and the operating system checks and uses that one. Journalling due to writing twice is supposed to slow down your performance some (I never noticed). Choice is yours. It takes me like a half hour to recover from multiple crashes from a dropped phone.
Oh and it depends on the ROM whether it is on, off or a choice is given. If you install a ROM with no journalling, it mostly can be turned on by doing a nand backup and restore. If you are stock, you are on.
Thanks that helped

Indeed it is. But before you ask a Q, double check that there isn't already an A. Save yourself the trouble of waiting, and save the rest of us from repeatedly writing the same thing. 99.9% of the time you're asking something that's been answered many times and can be easily found.
This one, for example, Kenny himself answered a couple weeks ago HERE.
And someone else asked months ago HERE.
And all I had to do was Google "Journaling XDA".
Journaling file systems use various techniques to keep a log of changes to files as they are written, and in the event of data corruption these logs can be used to repair the damage. This makes it much more unlikely that a crash will corrupt data. Here's a link to Wikipedia's entry:
http://en.wikipedia.org/wiki/Journaling_file_system
Anyway, using a non-journaling file system on your phone can result in corrupt files if a program FC's or the phone is shut down by pulling the battery. The benefits are faster file writes and better battery life because there is less writing to disk with each file change.
Thank you...in my head I compare it to computer write verifies, but it is more like the backup copy of the master boot record...got it..thanks. Was just trying to keep it simple.

Journaling is a stock feature, yes. Custom roms are not more prone to crashing, generally. It is apps that may crash, due to their own nature, or incompatibility with a rom, which will result in data loss in the absence of journaling.

If a question has been asked (and probably just freaking yesterday!) then yeah! SEARCH is your friend. Would you like to look for a thread you were posting in and see 20 questions on "what is an apk"? If people are able to find XDA they are able to use google. Not a high horse, but obviously can't teach basic knowledge here. And for the record, I answered the question as well...but as you were trolling too fast I guess you missed that.

It's already been posted, but journaling is a feature of journaling file systems.
Most operations performed by a file system consist of multiple fundamental "steps". Should the file system stop running (i.e., a bug causes the kernel to panic or the computer/phone loses power) before all the steps for a given operation completes, then the file system is left in an inconsistent state.
Consider the example of moving a file from one directory to another. In simplified terms, this consists of two steps: (i) copying the file to the destination directory, and (ii) deleting the file from the source directory. Now, suppose the phone crashes after copying the file (step i) but before deleting it (step ii). When the phone boots again, the file exists in both directories when it should only exist in one. That's the basic idea of file system inconsistency. Although that particular scenario is relatively harmless, there's more complicated situations in which a phone crash can result in deleted-but-not-freed data, half-written files, and all sorts of other inconsistencies.
Now, journaling file systems are different in that they maintain a transaction log (a journal) where the fundamental steps for operations are recorded before they are carried out. In the event of a crash, the file system replays the jounal on reboot and performs any outstanding operation that has been committed to the journal.
In the above example, a journaling file system would: (i) record in the journal that it is copying & deleting the file, (ii) commit the journal, then actually (iii) copy the file to the destionation directory, and (iv) delete the file from the source. In the event of a crash, the operation either has been committed to the journal, in which case it's verified that the subsequent steps were performed and are performed if not, or the operation hasn't been committed yet, in which case no changes have been made. This guarantees that, following a journal replay, the file system is always in a consistent state.
Now, it's true that maintaining a journal carries some performance penalty as operations have to be written to the file system twice. Modern file systems, like ext4, get around this by delaying the non-journal write operations until a later time when the file system is (relatively) idle. So the actual decrease in performance is minimal if any. This also means that running these file systems with journaling disabled is potentailly more dangerous than non-journaled file systems as operations may remain outstanding for far longer than they would otherwise, increasing their succeptability to loss in the event of a crash.
It's also worth noting that the primary purpose of file system journaling is to gurarantee file system consistency, not avoid data corruption. Most journaled file system only journal metadata, that is, only the operations carried out on a file are journaled, not the actual data content. This is why a battery pull is always a bad idea and should be avoided unless absolutely necessary.
Still, in the worst case, a journaling file system after reboot will only suffer data corruption in the files most recently modified before a crash, whereas a non-journaled file system may suffer corruption of the underlying file system structure, possibly rendering many non-recently modified files inaccessible. In other words, with a journaled file system, in the worst case you might have to "Clear data" on one or two apps to recover, whereas with a non-journaled one the entire file system might be hosed.

Just to note: journaling is irrelevant with regard to data corruption on an application-level crash. Any outstanding changes made by the application to the file system are still performed by the kernel, even after the application itself crashes.
Journaling protects in situation where the kernel itself is unable to complete any outstanding changes due to crash (kernel panic) or powerloss.
do you have to reenable journaling every time you flash a rom?

I would say, before rooting and after, before installing a custom rom, I got crashes all the time. About 70% were twLauncher (which is pathetic, this phone has convinced me I will never own another from Samsung - and I have a long history with Samsung phones) about 25% were from Maps (again, just sad) with the remaining 5% being other apps. twLauncher crashed more than any piece of software I have ever used on any electronics device in my life, something was wrong with it on this phone,i am quite sure it wasn't normal.
Either way, i am happy to say it wasn't the hardware (knock on wood). Not a single thing has crashed since installing Frankenstein Android. I am supremely happy with it.
In regards to three re-posting: I can't wait to hit 10 posts so that I can post in the thread about it Frankenstein. I have been lurking at xda a long time, finally decided I needed to post to share my experiences and gratitude to the developer. But I am having a hard time hitting the requisite 10 posts. Trying to post things that haven't been said before here is really hard if you aren't a developer yourself.

Mostly, if the ROM disables it. In other words every time you flash a no journal ROM it disables it.
The new Bonsai ROM will let you choose and then it will stick whether you reflash it or not.

1-click app cleaner - that works ??

Hi
On our beloved Nexus, I cant find a decent app cleaner, that act. works on ICS..
I used to use the app cache app, that had a scedule task within it. And that worked great on my desire..
Now I´v tried many different app, that seems to work, but they dont, None of them can clean all my cache files with 1-click - I have to manual do it with every program...
I would like to have a 1- click and perfektly also a scedule task within it (like the app cache from Infolife)
Why would you want to?

I have never experience any apps not working well on ICS (4.0.3), I've never needed to manage apps or run short of memory on any Android phone I've owned and because of my experience I think cache cleaners are absolutely pointless.

It's only for rooted phones.
And I'm not rooted...

I have never experience any apps not working well on ICS (4.0.3), I've never needed to manage apps or run short of memory on any Android phone I've owned and because of my experience I think cache cleaners are absolutely pointless.

This, I understand where this idea comes from since its a PC world right now, but I wish people would read up on these things beforehand. Android manages its memory and applications differently than your used to, and "clearing" your memory or cache is not recommended on our androidOS. It will actually slow down your phone and eat your battery.

Did you mean to quote me? You're talking like I don't already know that.

Yes.. You´r right and I know that... But even though, it seems to be "not that statement" for some of my apps..
The developer of the app claims that its ics ready.. but as I said before.. I see that the cache for this app is getting bigger og bigger and the app is getting slower and slower... If I do nothing it just happend that the app is crashing... From my experience is, that if I from time to time do a cashe cleaner (ie once or twice a day) it never lag/getting slower and then never crash..

Ha ha
Been there.. and tried a ton of different solutions, without any luck yet..
And since this forum should be a place where we can help each other etc.. I wrote here..
But I might be wrong...
So If I find a solution I should just keep it for my self.. instead of sharing the information for others??
How can it not work? It worked just fine for me.

I feel like this point needs to be re-iterated.
Free memory (including cache) is WASTED memory. If you interfere with the way Android manages its memory, you make things less efficient - apps that would otherwise be preloaded in the background will take more time and juice to start up. This is how Android was designed from the ground up, and it was designed that way for good reasons. Please save yourself from headaches and don't fsck with things you don't understand.

[Q] Note 8 VERY slow... now

I've had my 8 for several months but now it's starting to slow down. I have done everything except a factory reset (because thats just a pain in the ass) but it is still slow. Short of the reset does anyone have any ideas? Thanks!

I assume your battery drain is normal, or has not changed since the slowness has happened.
You have not stated if you rooted or custom ROM has been installed.
I found a few apps will do this time to time... depending on when they update. I always monitor my apps so troubling apps are always reverted back to their previous version.
You can use security 360 to monitor your tablet... It is a very good antivirus with some nice built in features. One is memory speed up and usage.
Basically it lets you know what apps are running in background, and releases them to speed up the tablet. I like it because it is like having 3 or 4 apps all into one and does not hog memory.
You can search the Q&A for battery drain if you have issues with battery as well ... there are many threads, so at least one will help. The lengthy threads have some good info near the end... as I try to help using simple methods that work with stock ROMs.

If not rooted, do so and you can eliminate apps that you don't use and that suck up RAM. You can as well move programs to an SD Card to increase the memory available.
Additionally, rooted or not you can go in and clean out the cache of all your apps. They build up over time.

Went to Best Buy and talked to the Samsung rep and he had the answer! First, get rid of SPB launcher then use Clean Sweep (in the store) to get rid of bloatware. Fast as Hell now! App only works on non-rooted I think. But it DOES work! Thanks for the help!

SPB launcher??? It must have been rooted. I have a mostly stock ROM... never had speed issues, but it is all in the choice of apps I install.
Given that many apps are developer driven, and from my experience with developers here on the forum, makes me cautious about installing apps. I install only what I need and does the job cleanly. Sometimes the best apps are buggy when being updated to run 4.4.x, as I seen that a lot since Xmas. Though May has been a good start for the year... many apps have been sorted out, but still iffy as there are thousands of apps to choose from.
I places a thread, and an answer to battery, and apps disabling in a simple and minimalistic method. If anyone is interested, they can search for posts by me... they are within this year.

You should not have needed to uninstall SPB unless you already had a whole bunch of apps. I have 200+ Apps with no issues.
Also Clean Sweep is a nice app, but you can do this already without the added app. Open you Google search, look at the bottom left hand tab, open it and you can do the same thing.

Nope. Not rooted and the launcher worked fine but apparently it slowed the system down. Now it's smokin'.
