Resigning apks

Usually when I theme an app I move it from /data/app to /system/app and then edit the files and do an update.zip to install the themed application. However, the problem with this is that I am not informed of market updates after moving the app to /system/app. Now I know that some people just edit the apk itself and resign it and that allows it to stay in /data/app.
I tried doing this, edited an apk, resigned it and that part went well. However, then I'm confused. Do I uninstall the app that's sitting in /data/app? Do I just cut and paste the new apk into /data/app? Or do I just install the new apk using Astro or something and let it overwrite the existing one.
I tried all three and it doesn't seem to work for me. It appears like everything went ok and it tells me application installed but none of the edits I make stick. Further, I noticed that in /data/app all the apks are named com.something.something.apk, whereas if you download an edited APK from some website it's usually named Facebook.apk, or Pandora.apk, etc.
So how the heck do I do this? I know the resigning is working because I edited the "Pandora.apk" that I downloaded from another source and resigned it, but when I try to pull from my phone I get the error that it either didn't install, or it does install but no changes happen.
How do you get com.something.something.apk to become Pandora.apk or Facebook.apk and then install it directly without having to do an update.zip??
anyone have a clue?
somebody anybody haha...why do my apps disappear from the app drawer after editing the apk in /data/app??
Dude i feel your pain, i've been in the same position.

What are you editing in the apk?

If your changing the name then the update can't find the apk, you cant move house but keep the same adress, you wont get your mail!!
Also if your wanting to update the edited apk, it will be overwritten by the updated version so your back to square one.
Hope this helps.
Search for apk tool, it will do what you want.

You won't be able to do that with a signed apk. It might be possible to replace pngs without unzipping. Try opening the apk as an archive and dragging in the new pngs.

Cyanogenmod gallery apk

Hello,
I have uninstalled CM gallery and would like to put it back, but havent found any separate apk. Could somebody please do it for me? Or if there is a way how to make Moto Gallery delete pictures properly, it would be fine. I've tried another build, but still the same problem.
Thank you
Jakub
Unpack the rom. Go to system/app and copy the apk (itll be in the folder usually called Gallery2).
Make a zip of the apk using zip me app from play store and flash through recovery.

Help with APK Editor- can't replace apks

I try to change some icons and pictures of theme I use.
inside the apk theme there's a few apks. What I did was open the apk as zip, and extract some apks I wanted to change their icons and pictures. I succeeded to change what I wanted with APK Editor. Next I tried to replace the "old" apks with the "new" I changed. so I opened APK Editor- "select an apk file"- choose the apk theme-"simple edit"- "assets"- the pencil of the apk I wanted to replace, and when I choose the "new" apk I changed, nothing happen. the apk didn't replace. I tried to do so with "select apk from app" but it won't find the theme.
I tried to copy past the "new" apk but I get an error when I try to install it.
Am I missing something? how can I change icons and picturrs in a theme?
No one knows?
Edit: nevermind I figure out how to do it
