Activity Monitor can start activities by using adb to invoke it.
This will allow us to set the user directory and autostart file from adb.
adb shell am start -n org.dolphinemu.dolphinemu/.gamelist.GameListActivity -e AutoStartFile /sdcard/AC.gcz -e UserDir /sdcard/dolphin-emu2/
This allows more automated testing to be done with Dolphin on Android.
