Relatively new to the community and coding in general, I would like to know if anyone could help me reprogram an android app. I'll be honest, I didn't create it, nor am I planning on claiming my goal with the software as my own (the end result will be for me alone). As it stands I can really only modify/hack pre-existing software and just need some help in the right direction. The app in question is ARChon Packager. For those who don't know what it is, it's a utility for "converting" Android APKs to Chrome/Chrome OS extensions. My problem: the output extensions are in ZIP archive format and must be extracted before they can be installed. I know how to do this, but I want to modify the output .zips to .crxs' for convenience. Yes I have changed the output file extension, but from what I understand the actual header must be different as well. The app has an asset that is a template ZIP. I believe it is the back-bone of the end result zips. It has a standard ZIP header so I signed it with my private keystore with SHA-1 encryption (as CRX info states it should be) and replaced the old template with the new one with no success. The output zip has the same header as before. I decompiled the DEX and found a sub-folder containing the zip/header paramaters. What do I need to do to to to accomplish my goal? Thanks for hearing me, and any help would be greatly appreciated.
