Root Change image files inside of .apk

[peteh98]

I extract an apk & navigate to the res folder and get the image I need. Then I change it how I want, name it how it was, and repack the .apk. Upon trying to install I get Application not installed. I used ZipSigner and it let me install, however my app force closed when I tried to open it. Any help is greatly appreciated.

The app I'm trying to edit is Handcent SMS

When I tried doing this I used 7zip to open the .apk file and then when I was done editing, I just stored it with an .apk extension. However that was on a different device and sometimes I still had problems because the .png files I was using were way bigger than the ones I was replacing.

Also, I always had better luck applying these type of changes to an .apk by flashing it while in recovery using a modified 'update.zip' file.

I have an 'update.zip' template file if you think it would help.

good luck

Try using 7zip, and just right click open archive

Then use somefthing like gimp to size accordingly

Also when you go to install, just use you file manager and put them in system/apps
And set permissions and ownership

I tried to install it as a system file before I edited it lol, also led to instant force closing. And about the file size thing yeah that sounds possible. How would I lower the size? And about the update.zip, I don't known anything about that. I'm willing to try if you thoroughly explain to me what to do lmao

Yes Handcent should not be installed as a system app. It would belong in /data/app. Are you uninstalling Handcent before trying to install your modified version?

Also as to the file size of the images there was a program that somebody used to help me out once. Something about .png, I just went to the CyanogenMod forums but can't find it now, sorry about that.

As far as the update.zip method, I have a template where you would open (not extract) it with 7zip, place your app in /data/app, close it, and put it on your phone and flash it like any other ROM. But you should make a nandroid backup first.

let me know if you want to try the last option and I will link my file.

I'll try uninstalling I didn't do that before. I'll let you know how that goes

uninstalling did not work.
