Android-Job run every time device is plugged in

In my Android app I need to run a background service every time the device is plugged in and idle (it should start after the user connects his device to the charger and end when he disconnects it).

What I want is a similar thing to listening for the ACTION_POWER_CONNECTED broadcast, but targeting Oreo this broadcast doesn't get sent.

I tried Android-Job from Evernote because it doesn't require Google Play Services, as Firebase JobDispatcher does.

 new JobRequest.Builder(DemoSyncJob.TAG)
            .setRequiresCharging(true)
            .setRequiresDeviceIdle(true)
            .build()
            .schedule();

The problem is that I don't want to have to schedule the job every time. Instead, I want to schedule the job once and have it run every time the user connects his device to the charger.

How can it be done? Thank you.

Because it's fine for me to run the job only once a day, but only when the device is plugged in, I have solved the problem like this:

public class ProcessPhotosJob extends Job {

    public static final String TAG = "process_photos_job";

    @NonNull
    @Override
    protected Result onRunJob(Params params) {
        new ProcessPhotos().execute(getContext());
        scheduleForTomorrow();
        return Result.SUCCESS;
    }

    public static void scheduleNow() {
        schedule(1);
    }

    public static void scheduleForTomorrow() {
        schedule(TimeUnit.DAYS.toMillis(1));
    }

    private static void schedule(long delayMillis) {
        if (!JobManager.instance().getAllJobRequestsForTag(TAG).isEmpty()) {
            // Job already scheduled
            return;
        }

        new JobRequest.Builder(ProcessPhotosJob.TAG)
            .setExecutionWindow(delayMillis, delayMillis + TimeUnit.DAYS.toMillis(1))
            .setRequiresCharging(true)
            .setRequiresDeviceIdle(true)
            .setRequirementsEnforced(true)
            .setUpdateCurrent(true)
            .build()
            .schedule();
    }
}

Hope it helps someone.
