Root How to repack an apk?

[RobertT22]

Okay playing around with my files I found how to unzip an apk file and view it's graphics and such.

What I want to do is change some images in the .apk file and re-zip it so I can then re-install it with the changes I made.

Does anyone know of a program that can re-zip apk files?

Thanks.

it's better to search for decompile and compiling apk (better results than repack)
