Ok, thanks. Will do...
Always sign a .apk if it has been decompiled. Doesn't matter if it system app or not.
My understanding is that system apps don't need to be signed since they are from Google, thus don't need the certification or is embedded in, while other APKs need that valid certificate to ensure that the APK can be installed by the system. Google does it to track where and who the aPKs are from.... sound about right?
Great guide. Nice job xkape. I've been trying to learn how to do some minor themeing and such, just trying to go from beginner to intermediate in the android universe you know what I'm saying. Definitely not something you can really halfass trying to learn it, you'll get nowhere it seems. For sure its going to take time to get familiarized with, but so did rooting and all that in the beginning, though this is a little more advanced, still gotta jump in with the same mindset you know. Anyways, thanks again for this excellent right up!! Been looking for somethin like this for a few days, just didn't really explore all the threads and such.dancedroid
