where do apps install to?

hello, I'm rooted and I wanted to change a few of my icons so they are changed in the app drawer. on my ipod touch I used iFile to find the app's folder and overwrite the icon.png, I tried to use Root Explorer to do this but I can't figure out where the apps install to. Could anyone give me a hint? thanks in advance.

System apps would be /system/app
User apps would be /data/app

thank you, sorry for the ignorant reply but all I found were apk's. the apps don't unpack files into a directory when installed? they stay and run from an apk on your phone?

Yes, and the data from them is stored in /data/data/

thank you, so if I don't see the icon files in data/data then I'm screwed as far as being able to change it?

Iirc here are the general steps.
Search to get the exact syntax.
Make a copy of the apk.
Rename the copy suffix to .zip from . apk
Extract the image stuff and replace it.
Repack the zip.
Rename it to apk

/system/app/ or sometimes /data/app/ if you modify an app you have to sign it again or the phone won't recognize it
EDIT: Use ninjamorph and just drag and drop the pings in there and here is myn's method of signing

Android 2.3 music player

I installed the honeycomb music player on my evo but I like the stock 2.3 player better. Does anyone have a link to download the stock 2.3 player? Thanks.

Here ya go. I pulled it out of SalvageMod 1.1
Most likely will need to be pushed to /system/app

You could just re-flash your ROM...

Root explorer
Copy the file over to system/apps and make the permissions the same as the rest of the folder.
If it asked to overwrite just hit yes.

In addition, make sure you're in r/w mode.

It tells me it has a problem parsing the package. Any suggestions?

You need to place the apk on the root of your sdcard, then open root explorer, enable r/w mode, navigate to sdcard, copy the apk, then get into the system/app folder, then paste.

What steps are you doing? I can't test the file because I don't have an evo at the moment.

I put it at the root of my SD card and then I copy and pasted it to /system/app and then I tried to install it. Could you explain to me what parsing is?

I also mounted r/w

Well the parsing error is cuz its having trouble reading the file.

So does that mean the file is corrupt?

Its possible, I would try re-downloading it.

The problem is because you're trying to install it. You don't install system apps. You just copy and paste it to the /system/app folder. THen make sure your permissions are set correctly, by long pressing on the Music.apk, and selecting permissions. Then be sure that user: read/write are both checked. After that, reboot. That's it. You don't click on 'install'. Copy, paste, check permissions, reboot.
or of course
adb remount
adb push Music.apk /system/app
adb reboot

I just tried all of that and it isnt installed after I reboot.

You sure to enable the correct positions? And after I get my setup going again, I'll try to recreate it as well.

You finally get your phone back? It's about time!
I just downloaded the Music.apk that I attatched, and can't get it to install. I'm on a Sense rom at the moment, and have never tried installing the Gingerbread Music.apk on a Sense rom, and doubt/not sure that it would even work to begin with. Either that, or maybe there are other files that need to go with it? Any other music player I've installed (HTC music player, MIUI player, and Honeycomb player) has no other necessary files, and you just push the .apk to /system/app and all is good. This one seems different, or it just doesn't work on Sense roms. I'm not sure. I tried the Music.apk from Evervolv too, but that wouldn't work either.
OP, what Rom is it that you're on? Are you currently on a Gingerbread rom? If so, just wipe cache, and dalvik cache, then re flash the ROM, as drmac suggested before. That will give you back all of the apps that came with the rom. If you are indeed on a Gingerbread ROM, you'll get the player you're after back. If you're not on a Gingerbread ROM, I'm not sure that the 2.3GB player will work on it to begin with.

[Q] Adding own apps into cm7?

hi guys, just switched to cm7.1, its a good rom, i was wondering if its possible to add your own apps into the rom and then flashing it? what i mean is to add your own essential apps into the rom and then to zip it so it uses up more rom space and leaves more internal space. if there is a method, can some one please give some idea on it. thanks

Of course it is. Just copy the app's apk from /data/app in the /system/app folder of the zip file.

Thanks but can you explain abit more in detail please, like if i put the apks in that folder, will the apps automaically be installed? and as for the rom zip file, will that need to be zipped up back in a special way? also will the apk's need to be signed with a special program? a small accurate guid would be sweet. thanks

There are two ways, either manually open the zip (no need to extract it) then just drag and drop your apk files to the System/app folder or data/app folder then close the window. Sometimes it doesnt work it depends I think on how the files was compiled or something.
Or use ROM manager. Look it up in the forums.
Edit: Its Rom Editor if my memory recalls it correctly.

No, just open the zip and stick the apk's in that directory. Then when you go to flash just disable signature verification..
I'm not sure as to how this will go about saving space though.. it's the same as installing apps AFAIK

In a way it does save space. I remove some apps that I don't need from the CM zip like ROM Manager, live wall paper etc and then add my apk files on system instead of it being saved in data folder.

Sthankyou, can i manually move apps in the data folder into the system with root explorer? i am s-off.

with root explorer yes, but I don't think they'll actually be installed just by putting them there..

Yes you can manually install apks to the system/app using root explorer. But you have to modify the permission of the apk file upon transferring. It is best that you first copy the apk from the data/app folder to sd. Then uninstall the app. Then use root explorer to transfer the app from sd to system/app. Update the permission then reboot.
Take note that not all apps will work with this method. Some apps just needed to be on the data/app folder based on my experience.

Hmm not sure how to installed those, the are zip files not apk?

Depends on what their recommendation is.
If its just a .zip with the .apk inside it, you can just unzip and install the .apk with a file explorer.
If it's a .zip made for flashing, just flash it via CWM.

Yea, the zip file didn't contain a apk, and via cwm it failed to flash!
not sure what to do now...

What folders are inside the ZIP? If it has things like "assets", "META-INF" and "res", change the file extension to .apk and install as normal.

yup that was it, just figured it out and installed them (when I downloaded a apk file which was exactly the same size).

Please need help regarding meta-inf

i installed "4.0.3 Leak On Screen Buttons" which was in zip having two folders
1 - meta- inf [which has a com folder (with files in it update-binary and updater-script) and with three files CERT.RSA, MANIFEST.MF and CERT.SF]
2 - system (in it framework-res.apk)
so i installed this zip via cwm, but i didn't liked the concept as it wasn't looking good,etc
so as i had already backed up my original framework-res.apk , so using root explorer i moved it back in sys/framework folder
restarted my phone and all got fine....
Though my question is as those files : update-binary and updater-script ---- CERT.RSA, MANIFEST.MF and CERT.SF are not searchable and i guess should not be deleted as they were just updated .. so still would they be impacting my phone or its all kool as i havn't been able to search them or delete them ?!
is it important to find and delete them or its no need for that and its ok ?!
Hope someone understands what i am trying to ask and reply appropriately please i would highly appreciate the same!

Think them like busybox (so you can mount delete etc)
And script file, that includes commands to do.
Every cwm zip files includes them. when you install zip file, these commands executed.

Just to clarify,
That folder contains the Zip signatures and file manifests. as well as the CWM controll scripts. ect. these should never be coppied to the phone on a flash. likewise if you edit them the zip will prob not work without resigning the zip.

Sorry if I didn't make it clear.
They are not flashed. Hence you can't find them. So no need to worry.

Awesome thank you! I understood they just help in probably installing that particular app giving its own correct signatures and file manifests w.e so it gets installed via cwm and nothing more . And as i just backed up my original framework-res.apk to framework folder so its ofcourse all back to normal, though my phone is fine always as it was, I just had this doubt in my mind and m glad it got cleared thanks again!!
Cheers!!

Where did you place the Meta-INF files? I know system files goto system/framework but I cant find where Meta-INF files go. I'm using a root file manager.

You are not correct about the system files. And I recommend you do some more reading on how these zips work.
Metainf is FOR THE ZIP. And has been prety well explained above.
