Manual flashing SuperSU (2.82) on AVD armv7 android 6 - SDK23 emulator

SuperSUFlash.sh

#!/bin/sh
#
# @0xGr00t, 2018
# This is a simple shell script that does exactly what SuperSU guided in their code.
# Tested on AVD android 6 armv7 emulator (sdk23) with macOS host
# Before you run this, make sure you have downloaded SuperSu flashable zip from their site, and cd into it
# To this to work properly, run the emulator with -no-snapshot -writable-system flags
# For example: MacBook-Pro-2:tools matandobr$  ./emulator -no-snapshot -writable-system @Nexus5API23
# cd into the extracted SuperSU-v2.82 folder, and run it from there.
# There is one issue I faced - when starting the emulator it won't boot until you disable SELinux (adb shell setenforce 0)
# After the boot completes you can turn it back on.
# Make sure you restart the emulator after running the script so the system app will installed properly
# GoodLuck <3
