#####################################################################

|
|
# This script will setup an environment with minimal Magisk that
|
|
# the Magisk app will be happy to run properly within the official
|
|
# emulator bundled with Android Studio (AVD).
|
|
#
|
|
# ONLY use this script for developing the Magisk app or root apps
|
|
# in the emulator. The constructed Magisk environment is not a
|
|
# fully functional one as if it is running on an actual device.
|
|
#
|
|
# The script assumes you are using x64 emulator images.
|
|
# Build binaries with `./build.py binary` before running this script.
