在 Android 上定期安排后台任务

Question

I'm working on an app where I have to read data from multiple sensors and send it to a remote server every 15 minutes. This has to be done when the app is closed/killed as well and I also have to be sure it always executes. I also want to be sure it happens (almost) exactly every 15 minutes (+-1 minute difference is the upper limit).

At this point, I've found 3 options: using Workmanager, Alarmmanager or using a foreground service. Following the documentation , Workmanager seems the way to go for background tasks, however, after having done some reading, Alarmmanager seems to be a safer choice (Workmanager sometimes has troubles with doze mode, and the timing isn't exact because it uses a flex period of at least 5 minutes). And a foreground service is not really allowed for this kind of task (it's not really long running, it's just a periodic task) and is being limited in newer Android versions. Do you think it would be a good idea to use an Alarmmanger for this task, or should I use something else? Thanks!

TODO Background scheduling.. You can use this method todo your stuff..

KOTLIN;

val service = Executors.newSingleThreadScheduledExecutor()
        val handler = Handler(Looper.getMainLooper())
        service.scheduleAtFixedRate({
            handler.run {
                // Do your stuff here, It gets loop every 15 Minutes
            }
        }, 0, 15, TimeUnit.MINUTES);

JAVA;

  ScheduledExecutorService service = Executors.newSingleThreadScheduledExecutor();
        Handler handler = new Handler(Looper.getMainLooper());

        service.scheduleAtFixedRate(() -> {
            handler.post(() -> {
                // Do your stuff here, It gets loop every 15 Minutes
            });
        }, 0, 15, TimeUnit.MINUTES);
