# Magisk Manager will be happy to run properly within the official

# emulator bundled with Android Studio (AVD).

# ONLY use this script for developing Magisk Manager in the

# emulator. The constructed Magisk environment is not a fully
|
||||
# functional one as if it is running on an actual device.
|
||||
# The script only supports non system-as-root images, meaning
|
||||
# AVD images that are newer than API 25 are NOT supported.
|

# This script is meant to be used for emulators running obscure
|

# Android versions; use an actual device for modern Androids.

# ONLY use this script for developing Magisk Manager or root apps

# The script assumes you are using x86 emulator images.

# The script assumes you are using x86/x64 emulator images.
