How to make AVD system and file-system writable?
Raw
writable-avd.md

Source: https://www.linkedin.com/pulse/android-emulator-tips-security-testers-divya-mudgal/

List created Android AVDs:

emulator -list-avds

Start an AVD (without Play Store) with writable "/system":

emulator -avd Pixel_3_XL_API_26 -writable-system

Start ADB daemon as root:

adb root

Remount "/system" because it is by default mounted as "read-only" even if "-writable-system" is used:

adb remount

Get shell access on AVD and change current user to "root":

adb shell

su

Remount "/system" with read-write access:

mount -o rw,remount /system

mount -o rw,remount /
