# AVD Magisk Setup
|
|
#####################################################################
|
|
#
|
|
# Support API level: 23 - 34
|
|
#
|
|
# With an emulator booted and accessible via ADB, usage:
|
|
# ./build.py emulator
|
|
#
|
|
# This script will stop zygote, simulate the Magisk start up process
|
|
# that would've happened before zygote was started, and finally
|
|
# restart zygote. This is useful for setting up the emulator for
|
|
# developing Magisk, testing modules, and developing root apps using
|
|
# the official Android emulator (AVD) instead of a real device.
|
|
#
|
|
# This only covers the "core" features of Magisk. For testing
|
|
# magiskinit, please checkout avd_patch.sh.
