Hello There Everyone!,
To clarify the title...
Is there a way to change, modify, convert, etc... an App Installer (.apk) to a Flashable Installer (.zip).
I'm not referring to just creating a zip to simply copy the apk file to its desired directory but, to either install the app as a new app and/or upgrade an existing one in the same/similar fashion as would an apk itself would be installed.
I tried to search around and the results aren't specific to what I'm asking and reflects the copying of the apk file rather than the installing of it.
I hope that I had explained this okay via text... :-)
Thank you very much for your time and understanding with this question!
