Init.d is not available on GOS as far as I know. I wanted to make simple binaries wich run in the background to automate some things like automated backup for WhatsApp Chats via folders so nobody has to use google for that. Its just an experiement and i think apps for that are to much bloat.
Is it possible to run binaries via adb in the background, persistent after a reboot (the background job starts after a reboot automatically) without recompiling GOS?
