How do you background work in Android? Easy, just use one of the following (which may or may not work as expected depending on what version of Android it's running on, or how long it happens to run for, or what's in the background or foreground, or what triggers it, or what wind the direction is blowing in, or how long since you last gave a fuck)

background Service, or foreground Service, or IntentService, or AlarmManager, or JobScheduler, or WorkManager, or FUCK YOU ANDROID
