I've been trying to edit a few apk files by extracting the png's and editing them to my liking..
however some of the apk's i try to modify wont work after i edit them..
does anyone know of a good step by step, or have any advice.. here is what i've been doing:
adb pull (pandora.apk)
find the file i want to change.. in this case it is.. pandora.zip/res/drawable-hdpi/widget_background.png
copy that file to desktop and edit it in PS
move it back to zip folder and replace old one..
sign package using SDK "sign package" tool
adb push back to original location... in this case /system/app
do i need to uninstall and reinstall using new apk? or just push it over the original?
