# AVD MagiskInit Setup

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

|
|
# Support API level: 23 - 34
|
|

|
|
# With an emulator booted and accessible via ADB, usage:
|
|
# ./build.py avd_patch path/to/booted/avd-image/ramdisk.img
|
|
#
|
|
# The purpose of this script is to patch AVD ramdisk.img and do a
|
|
# full integration test of magiskinit under several circumstances.
|
|
# After patching ramdisk.img, close the emulator, then select
|
|
# "Cold Boot Now" in AVD Manager to force a full reboot.

# rootfs with early mount: API 26 - 27
