Rom dev - Android Q&A, Help & Troubleshooting

I am a buddin dev.
What is the use of data/app folder? And, how is is different from system/app? :cyclops:

Data/app is the location for user apps...mainly the ones you get from the play store, apps in that directory can easily be uninstalled by the user through the settings/app manager
System/apps are system apps, they are fairly permanent...only way to uninstall them is with titanium back up, a root explorer or some other system app uninstaller...either way you go root is required to uninstall them

[Q] Removing Unnecessary Application not rooted

I have an HTC Tattoo .. how can I remove some unnecessary application without rooting the phone..
That's not possible. You need root permission to delete system apps.
how to remove unnecessary application like calculator, google maps, peep, my phone is rooted
You can use an app called titanium backup and uninstall what you want

Titanium depends on Busybox and for such operations root also required.
2OP: never delete any Google service, otherwise, Market won't work. It has strange dependencies upon Gtalk, Maps, etc.

root explorer or root manager can do this with rooted phone
root explorer go to \system\app\ delete any app apk & delete odex also
if not del take permission
How about some good old Linux!
First, adb remount.
Now enter shell, from ADB, type adb shell. Then,
Code:
ls /system/app
Now you see a list of alle apps on your phone. To remove an app type
rm /system/app/appname.apk
Cheers

[Q] How to convert User apps to System app?

I need to know how to convert User apps to System apps. I know Titanium Backup can do it but I don't want to pay 7 bucks for the pro version.
Do I just move the APK from the /data/app to /system/app?
I am on a deodexed ROM so no odex files to move.
If I convert these user apps to system apps will it raise the OOM value? That's what I am after really.
GO Launcher gets killed way to easily. And while I am at it, I what to move GO SMS and Miren Browser if this will work.
If you have problems with Go Launcher quitting, then try the options called "System persistent" and "Prevent Force Close" in the app settings if you haven't tried that.
Yea I have that selected. The thing is, my phone doesn't have alot of memory. I have about 120 MB of ram with all apps closed and only about 40 MB free till android kills apps. So only really have about 80mb.

Friend see this app, can move to system, is good, see the oficial thread in samdroid
forum.samdroid.net/f10/apps2rom-root-move-your-updated-applications-system-rom-5690/
Once you move the apk to /system/app, remember to set the permissions to rw-r--r-- and reboot. I'm not sure if this will change the oom value or not, but I think it does. If it doesn't work, try V6 Supercharger & apply the bulletproof launcher. It may help with other memory issues as well. You can also "bulletproof" other apps, but I'm not quite sure how as I haven't played with those options.

maybe you have to generate the .odex files for those new system apps, you moved to system!
like this:
start your terminal emulator and type:
to change in the right directory
cd /system/app
use root rights with su and generate the data
su
dexopt-wrapper Vending.apk Vending.odex
or
dexopt-wrapper YouTube.apk YouTube.odex
and dont forget to set the read write permissions the right way
no reboot and wipe the dalvik cache!
For those not converted apps, how did you convert them?
.. maybe really try to move them not with /system/app mover, but by copy pasting them in a file explorer.

I'm trying to convert 'launcher2.apk' on my LG optimus 1 with offical cm7 into a system app, to replace adw launcher. Any ideas? :confused
In my experience not all apps works good as system apps. I have to try every time an update comes too.

[Q] frozen apps

Is there a list of apps that can be disabled for this phone?
Don't we need root?
Not an iPhone.....
Just go through the list, its lets you do quite a few of them in app management
Sent from my SCH-I605 using xda app-developers app
Can someone give me a list of what they froze, I think I got most of them but stuff like Music Hub, Music Player, Viewdini, VPN Client, Zappos I have no idea about
I have only removed the bloatware from one other phone (HTC incredible) and the process went like this:
1. Open root explore and go to system/app
2. Change from read/only to read/write
3. Select the apps from the system/app that I want to remove
4. Move those apps to a new folder that I named app.disabled in the system file.
Does this same process work the the Note 2?

Edit: nevermind, just used TB to freeze apps
Works well, especially as it requires only root and a good file manager [e.g. ES].. I had been dependent on tools like TB before your post. Thanks for the lesson.

did you change the permissions for apk
Please don't do that. Here is the reason - In the Android manifest.XML, there are many permissions which are required by the app. Some special permissions are granted only to system apps. Normal apps cannot have those permissions. So, when you move the system app to data/app you are trying to convert a system app to a normal app. Hence it will never work. However there are a few system apps which can be safely converted to normal apps like the pre loaded Facebook app etc.

Hmmm.....tell us which system apps you want to move to data/app????
there only a few system app that can be move without having problem while using it....the best choice to move it is to use System Cleanup....it can move system app to data/app, delete system app, freeze app or disable autorun in app....you can view which system app can be deleted...those can be deleted also can be move to data/app....

Delete system/pre-installed apps on a rooted device

Hi,
I'd like to know how to safely delete system or ROM pre-installed applications that don't offer an "Uninstall" option. I am rooted and running 5.0.2 on a Nexus 6. I know I could do this with Titanium or other similar apps but my point is to not install a specific app just for deleting apps if I can find the correct path/file from Root Explorer and remove it myself.
Thanks

from my experience the best that you can do is to use root explorer and goto system/app or system/priv-app and delete folder-app you do not need, then goto data/dalvik-cache, search for apk name and delete also program *.dex, so this is a clean method, make a reboot for clearing apk data !
It's safer to rename the app instead of deleting it... "freezing" apps often just add ".fro" to the app's name (whatever.apk.fro, for example) to keep it from appearing in your app launcher or loading. If anything goes wrong because of the "missing" app, you can easily restore it.
