Hi all!
I was browsing the /data folder, looking for what the hell does eat up all my 420Mb on the Xperia Arc S partition.
I found that the folder /data/local contains copies of some *.apk files that also exists on /system/app with the exact same size!
Anyone know the purpose of this folder and if I can safely delete the apks inside it safely, without affecting their usage?
It is occupying 60Mb of space,,
Thanks!
/system/app - contains system apps
/data/app - contains user apps
/data/local - ? On my device, the /data/local folder is empty, save for 2 folders: download and tmp
Backup, erase. Don't like it? Restore.

Thanks for the suggestion.
I have done this and so far no harm has come to the apps that were on /data/local.
If anything unusual happens I will restore with cwm.
I just got 60 Mb back on /data partition!

It has been asked before... and I think I have the hang of some of it... BUT...
I have been modifying some of my app icons via xRecovery. The method I used was via 7zip and replaced the iconfiles through there... I have been using [FW 2.1.1.A.0.6] Black HTC Theme for X8/X10mini/pro ~XRECOVERY~ [UPDATE:11.03.2011] and the enclosed "app-update.zip" via xRecovery.
Now to my questions!
1: Where do I find my installed apps (apk´s) on the internal storage? I use RootExplorer and was thinking about copying apk´s to the memorycard and then transfer to my PC, modify them there
2: Can I use the "app-update.zip" method to all selected apps? For example... the App-update.zip" contains "SemcContacts.apk" and it workes fine to change this way... but can I just put "handcent.apk" or "Ndrive.apk" in the same "app-update.zip" without any problems?
I hope I have explained so you guys can understand what I´m talking about...
Best regards

1: "/system/app" and "/data/app"
2: if you do it with 7zip yeah it will work if you give them the same name and place in the app-update.zip
example you want to replace "com.blablabla.hey" in direction /data/app
you need to name the app "com.blablabla.hey" and in the app-update.zip it need to be placed in the dir /data/app
Hmmm... Ok, I found the *apk´s under "system/app"... no worries there. I just replace the png "CalendarProvider.apk" that represents the icon. via 7zip. After that I implement it with "app-update.zip"
"app-update.zip" contains two folders... META-INF and system. The system-folder contains the folder app witch has some apk´s... That these apk´s is coming from "system/app" on the internal storage I understand. So in order to install modified apk from "data/app" I have to create a folder in my apps-update that is named data/apps with my modified apk´s?
So in the end my "apps-update" will look like this:
apps-update.zip containing Folders META_INF, system and data coresponding to the apk´s I have changed...
All this will be done with 7zip without extracting anything....

yup your right BUT!
in META_INF if you click through all maps that are in there you will end up with a file called update-script
drag it on you desktop
open it with wordpad(!)
search this line "copy_dir PACKAGE:system SYSTEM:"
and paste this underneath it
"copy_dir PACKAGE:data DATA:"
without the quotes ofc

Awww...sweet. That was just what I needed to hear. I was sure that something like that had to be added!
BTW... the modified apk´s will overwrite the original ones, right? No backup-crap (like Windows) is made by the Xrecovery installation?
Thanx!!!
Worked like a charm!!!
Thank you for all the help!!!
Well...I take that back...
I just replaced the iconfiles with my modded ones... the same name and size as the original. Everything done within 7zip...
All the apk´s within the "system"-folder worked fine... bur the ones within the "data"-folder uninstalled instead. In Appbrain the are still installed but in the drawer the are gone. I had a couple of them as shortcuts on my homescreen and the I get the message that thay are not present on my system.
Thank god it was only a couple of apk´s i modded so I reinstalled them via Market.
I added the line as You described but something must have happened?

Do you guys know of any problems that I may encounter if I use a CWM script to change some settings that are stored in the /data/data folder? I have created a script that copies over some XML files to the shared_prefs folders belonging to the jkay and system settings apps. Do these programs store an MD5 hash of these files like many of the games do?
I want to add a feature to my app so i can backup so that the user can backup certain shared_prefs files of other apps (located in data/data/package,name/shared_prefs). I dont want to modify them, just backup and overwrite.
My app has root privileges.
Ive tried this a few times but i cant get it to work, im just getting a file not found error when uploading. I realised that its because the files dont have read permission to just anybody.
So what can i do to get around this?
Ive tried mounting data/ as read/write but that didnt work or i did it wrong.
Thanks
You have to chown the files properly. Apps owners are usually number like app_100, app_101, etc. Some files in data/data are system owned so its easy, when you copy files to your sdcard they lose ownership so it has to be fixed when they get put back in data/data.

But i can copy other files from the data/data/package/name/files directory. Are you sure i cant link to it like that?
And i dont know what chown is :/ little help please?
edit: just looked into chown a bit, i know a little of what it does but have no idea how to use it. Cant i get what i would write using an example file?
Hello Guys,
I am trying to make/edit my first custom rom (forgive my noob mistakes). As base i am using the Oxygen rom. This rom has all his apps stored in system/app. I inserted an launcher(hololauncher), keyboard(custom htcime) and gallery(quickpick) apk in this folder, but after the rom is flashed these apps are causing fc's and the gallery app isnt even flashed.
I know that not every apk can be placed in the system/app folder, but how can i ensure that these apps will install correctly during flashing.
Depends on apps.
The most common mistake is forgetting to set the permissions to rw-r-r.
Also some apps need their lib files (usually end in .so) in a specific location, like quickpic that can't be turned into a system app just by putting it in system/app address.
Edit: you can ensure these apps are installed correctly by testing.
1 install them normally and convert them to system apps.
2 write down where each of their parts end up (some will always need stuff in data/app or something similar.
4 use a root explorer or adb to copy those files to your pc.
5 modify the flashable zip. Add the files you just copied and modify the updater-script to make sure those files get flashed to the correct location (you might need to include mount data commands if any of the files flash to data/)
6 test!
Some apps might require actual edition by decompiling them, but the above should work for most.

How can I convert it to a system app when it already is installed normally ?
I also saw the option to make a data/app folder, isn't that easier ?
(Take in consideration that I don't use kitchen or adb tools, just winrar and notepadcc )

Not talking about adb and kitchen.
there are many app managing apps out there (titanium backup, link2sd) that can convert apps to system apps.
The updater script is in META-INF of the flashable zip (can be edited with notepad).
You only need a rooted device to see where the apps keep their data and copy those files.

Ok that is clear, thanks. What do you think about data/app. Will this work ?

Yeah, flashing to data app is an option, but if a data wipe or factory reset is applied after flashing the rom (to correct a bootloop for example), those apps are gone.
i want to save some custom apps that i have moved to system when i install CM updates. so i want to add them to a script in addon.d
these app folders seem to have the apk and an empty lib folder. adding the apk seems easy, but how exactly do i tell the script to also backup the 'lib' folder and restore it?
thanks.
