#!/bin/bash
#
# Prepare the app for cloning before repacking it. This will allow to install
# several versions in parallel on the same device
#
# Changing the package name from dji.go.v4 to new name will have side effects.
# List of know side effects :
#
# Script Arguments :
#
# First arg  : directory of the "decompile-out" to be prepared
# Second arg : name of clone package e.g. dji.go.v5
#            : script has only been tested with package name of same length
#			 : (char count) as the original one (9 chars)
# Third arg  : Package label name
#
# More specifically, the following URL will automatically trigger generating
# an API key for the newpackagename packahe (replace in URL) matching testkey used for signing modded app
#
# example URL : !!! substitute newpackagename before using !!!
#
# e.g. command example :
#
# ./prepare_cloning.sh ijd.og.v5 decompile_out "IJD OG 4.1.14 modded"
