Usage

a2ll [no parameters: interactive mode]
a2ll [-shortcut, --argument] [value]

Arguments:
-a, --apk, Location of APK to use
-o, --obb, Location of OBB to use
-i, --ini, Location of INI to use
-r, --remove, Uninstall thoroughly if installing in headset doesn't work
-p, --open, Wakes headset and opens game automatically once finished
-s, --strip, Stripts permissions to skip permission prompts on first launch
-l, --logs, Pull A2 logs for debugging
-c, --commandline, Specify commandline options to pass to A2
-so, --so, Inject a custom .so file into the APK

How does it work?

Rebuilding the APK with debugging enabled gives permission to access the game files without root.
From there we can place an Engine.ini which overrides the games file letting us bypass authentication and load straight into the map without connecting to any servers.
