patch_apk.sh

#!/bin/bash
#
# Part of original RunMe.sh script that handles patching the apk found
# in subdirectory PutApkHere that have been decompiled
#
# script is modified to take 3 arguments
#
# First argument  : name of the decompiled apk directory e.g. decompile_out
# Second argument : timestamp for generating the logs with autogeneration if empty
# Third argument : bool value if additional languages should be added or not
