This script sideloads an APK and its corresponding OBB file to an Android device.

sideload.sh

#!/bin/sh

# This script installs an APK and its corresponding OBB file to an Android device.
# It requires the path to the directory containing the APK and OBB file(s) as an input parameter.
# The script will find the APK and the OBB file with the highest version number in the directory,
# then install the APK and upload the OBB file to the appropriate location on the device.
# It also handles uninstalling the existing APK, creating the OBB directory if necessary, 
# and removing any existing OBB files for the APK.
#
# The script relies on Android Debug Bridge (adb) to communicate with the device. 
# Ensure that adb is installed and set up correctly on your system before using this script.
#
# Usage:
# ./sideload.sh /path/to/directory
