How to clean the cache (globally) in the internal memory?

I think I should clean the cache a bit, i tried to uninstall some apps but maybe it isn't enough. The Android market is unable to download new apps while BlackDroid still works

I have the same problem, i installed quite a few appz and then removed them, now out of memory from left over installs and not half the appz as orig installed.

I'm interested in finding out this as one. This utility is badly needed.
Don't know how long before we will be able to choose location where to install appications i.e., ofcourse SD card.

We need it rooted fpr apps2sd, but still waiting so we must just be patient.

I don't know if it's the same thing you're talking about, but you can clear the cache from the recovery menu.

This does not require root:

But you cannot clear all caches at once. Still handy though.

Awesome find gogol, very handy indeed, less time consuming... would like to see a clean all feature though!
EDIT: Unfortunatly, Android does not offer the possibility to delete data of other applications (on unrooted phones) for security reasons ... the only way to clear an application cache is to call a system application which is allowed to delete it, that's the reason why several caches can't be cleared with one click, just like with this application.
Alternatively, instead of installing such an app, you can practically achieve the same results by going to settings>apps>manage apps
then menu and sort by size
the top 3 or so you can quickly clear and be done.

A quality utility, thanks

Ok I done a factory reset and gained 128 meg Install lots of appz and still have over 90meg free

[Q] Is there a temporary files folder in android?

Some folder that you can clean once in a while to free internal memory?

each app has its own cache', try an app like cache mate (Paid) or cache cleaner (free), both are great chache' cleaners

Linux does not work like windows, you should not need to do this, it won't free too much space.
If you clean this cache out then use those apps again it won't take long for the cache to build right back up again.

OK, so you have any other suggestions for clearing some internal space?
except moving apps2sd 'cause i've done it?
I found a temp folder /data/drm/tmp that sometimes contains the .apk file after you already used them, someone know anything about that?

it will free up space on rarely used apps tho, and especialy the market cache can rob 2mb+ when downloading

Try moving Dalvik cache to sd if you want, but if you have 100mb free and your apps are already on the sd I really don't see what your worrying about 100mb is loads when its just being used by cache.

But it's the temp folder within it. I deleted two big .apk file that were there. I know it's just apps that I just installed, it had the full name of the .apks I used. And nothing went wrong ^^
BTW, How do I move delvik cache to sd? How much space does it take? Can it affect the apps performance?

It can free up loads of space, and yes it can affect performance depending on your sd card.
But you missed the big point!
If you move apps2sd then Dalvik Cache to sd the only thing left in data will be the phones data which is tiny, so in effect you will be having over 100mb of wasted space in your phone. Why do you want this?

If I understand correctly then, moving delvik cache can seriously mess up the phone right?
I have now 85MB free on my phone, I think the more the better for phone performance =]

Why do you think this?
First of all, the memory we are talking about here is being used for disk space, so having more available just means you have more disk space!
Secondly, having loads of free program memory (i.e. the memory used by running programs, as opposed to disk space) won't improve performance anyway. Since Android doesn't use swap, once it starts running low on program memory it will start killing off applications, and will endeavour to optimize memory usage on it's own.

thanks for the info =]

[Q] Removing stock apps to save space?

I noticed some threads for different phones with regard to this but didn't see an answer for the EVO so I'll ask here.
I would like more space on my phone as I'm tired of seeing the little low space hard drive icon. I've already moved all the apps to SD via app2SD. I was thinking of installing the latest rooted stock Sprint ROM (3.70.651.1) and then deleting the stock apps that I do not use but I have read elsewhere that this will, in fact, not free up any more space for applications. Is this true?
If so, can I get a recommendation for the "most stock" ROM that's stripped of the Sprint added apps. If it has some ubiquitous and useful add-ons than that is OK
Thanks!

There's a couple of ROMs in the Dev section that are optimized for speed, and I'd recommend those. A lot of them have them already removed, but you can remove the ones that aren't

Thanks for the response... I apologize if I didn't state my question correctly. I understand that I can remove the apps that I want if I'm rooted, what I'm not sure about is if that space will be made available for other applications when I do remove the programs (in ROM) that I do not want.
Hope that clarifies the question.

A small amount of space will be freed. If you move Dalvik Cache to the Cache partition this will free up a lot more space than removing apps.

That sounds intriguing... can you point me to a "how-to" link or someplace where I can learn more about how to do this?

Search on XDA for "move dalvik to cache". There should be a zip file you can download that will do it for you.

Thanks again for the info. I did as you suggested and now have 266 MB left where before I had less than 50. Using ap2sd with Azrael ROM and do far have not run into any issues. Keeping my fingers crossed.

Note, however, that most of the stock apps are in your system partition. The free space you care about for installing apps is in the data partition. So removing them doesn't free up the space you care about. Even on ROMs that have removed them, I'm not sure if they actually do (or can) resize the partitions to give you the space where it counts (/data).
You can, however, move apps to the system partition if you want. I've done this with some of the updates to stock apps -- GMail, Qik, and Flash, for example. That's freed some space up.

This sounds like it is worthwhile to learn how to do. Is there a thread or program that you could point me to for some guidance on how to do this?
I've also read that ap2sd can move programs that have not yet been modified to enable the regular android 2.2 "move to SD" function to work; but after flashing that app and using it to move the Dalvik cache I do see any obvious front-end for it.

Basically you just move the APK file from /data/app to /system/app using ES File Explorer (need to enable root mode in prefs) or Root Explorer. Or you can do it with adb or even terminal emulator on the phone if you prefer. I think Titanium Backup Pro (the paid version) has an ability to do this too. You also want to look in /system/app and see if there's an older version under some other name that should be deleted. Titanium Pro may handle this part for you automatically as well. I haven't bought it yet, so I'm not sure (though I plan to, the free version is great and the paid version adds some nice things). I think you can still get updates from the market after you've done this, but the update will go to /data/app. You'd need to move it and delete the prior version again after receiving such an update.
I haven't enabled a2sd yet. My understanding is that it's not so much something you need a front end for. Once you set it up, that's just where your apps go. You don't move your apps to the sd card manually. I could be wrong. I used whatever form of a2sd was available for XDAndroid on my old Touch, but that's been a little while and the DarkStar A2SD that people use might be a little different than that method. I haven't done it at all yet on the evo.

Thank you sir, that's very good info and I'll give it a shot.

[Q] Too many apps can clutter the system ....!

Alright I just flashed a new ROM with new KERNEL and I spent hours and hours to SET-UP the phone now it's in perfect condition ...
My question is if we install and then uninstall new apps will it leave random files in the system, like in windows uninstalling programs leave dlls, registries and temp files, resulting in cluttering, messing up and slowing down the system ...? Does Android work differently ...? Is it possible to try bunch of new apps without messing it up ...?
Pardon me if it's a repost, but I couldn't find anything smiler.

I've always been pretty curious about this as well. I'm sorry I can't help, but I'm going to keep an eye on this thread to see if anyone has an answer.

i heard it does create cache files and it should handle accordingly, but curious nonetheless as well...

You can use a free app in market called cache cleaner or boot into recovery and wipe cache and dalvik cache
Also can download this and flash periodically http://db.tt/pT7bKYi

I am more curios about permanent files that might have been left after You uninstall an app. Clearing those undesired, useless, junk files is the main issue ...!

I don't know about lib files or anything like that, but if I look at the contents of my sdcard (which I need to clean out), I have a ton of folders left over from apps I uninstalled a while ago.
Sent from my blah blah blah blah

they won't be in your RAM, so unless you get messages about low storage space (on stock roms) then i wouldnt worry about it.
i've installed and uninstalled 100's of apps to test this. because my dad when i was younger would always yell at me for installing/ uninstalling programs on windows because it causes fragmentation, registry errors ect ect ect.
i can say if you have 100 apps installed then you uninstall 90 of them you won't notice. your SD card will have a bunch of extra folders afterwards though

Nexus 7 flo users please help me asap

hello i decided to update my nexus 7 flo to the latest stock marshmallow this morning but im in dilemma now.. as i have only 235kb memory left in my system rom. please help how to free it .. i only have atleast 10 apps installed now and i really wonder why it takes that much of memory... by the way.. my n7 flo is rooted already. please see my ss below

It's rooted, so no OTA is possible. You can only do this - and they wrote:
"Caution: Flashing a new system image deletes all user data. Be certain to first backup any personal data such as photos"​
Then, what's the dilemma when you have no choice?

with all due respect sir, i just want to ask if theres a way to free it up my system memory, im experiencing now some lagginess of my tablet which i think its because of that low system memory, so is there any way to delete some system app like map, keep, hangouts etc because i really dont need them.

I`m guessing that Your Titanium backups has taken a lot of your storage.... You could go in and delete the backups You dont need?.... Also you could use Titanium to uninstall system apps...... and cleaning up the temp cache of used apps could free up some more....
I have the 16gb version and it is not alot of storage to use on it, the micro sd slot is one thing I really miss from Nexus ..... but I mostly use a usb stick for movies etc :good: ....
You could also use the cleaner script found here to free about 224mb of storage : http://forum.xda-developers.com/nexus-7-2013/development/rom-bad-boyz-nexus-7-stock-rooted-t3219148

The stock firmware fills nearly all of system and that's ok. It's not slowing you down.
If you need more space in the system partition for some reason delete system apps with TB like mentioned above.

Ya I tried that system cleaner but it didn't work for me, I got bootloop instead.
