Anyway, Google PS decided that if ApkEditor wanted to remsin on the PS it would have to remove rebuild and install functions from the app. At some point Google PS made changes to its security policy that forced the developer to make the app less functional. Without the ability to rebuild,sign and install what good is it?
The best one is ApkToolX android app but its tricky to get it working properly. Root is required but it requires going into system framework app and importing it as framework and a few other system app to import and few other processes are involved. Its by far the best for reverse engineering an app (even systems apps).
As far as programming, I don't know java or simali. I can't even spell that good
