Has anyone ever messed with this? Reason I ask is because we have been theming apps, but they won't work if you try to install them, so we must push them to system/app to get them to work. I just broke down Pandora, changed all the graphics, used the apkbuilder.bat with the correct syntax to put the folder structure back together, installed on my phone, and it came up with all my changes. I'm just trying to understand because if you look at different ROM's sometimes they will theme apps but they will always push them to system. Basically, you can use 7zip to extract any .apk you pull from your phone, go in to the res folders and change any images you want, move the folder structure to your android-sdk-windows/tools folder, then use apkbuilder to put it back together. And it works perfectly. I guess it's kinda the same thing as using eclipse, EXCEPT, with Eclipse you have no way of importing the file system, you get parsing errors when trying to import a binary xml it seems, but this works perfectly as a command line tool for the same thing.
