Handle device features in codename one

Question

for learning purposes, I am trying to write a simple sleep timer app. Purpose should be to have a picker, select a number of minutes and after that time, perform certain actions. Most importantly, activate flight mode and close all other applications to save the battery.

I have a custom picker and my runnable thread, which works fine:

@Override
public void run() {

    while((System.currentTimeMillis() - startTime ) / 1000 < minutes){
        try {
            Thread.sleep(1000);
        } catch (InterruptedException e) {
            System.out.println("interrupted, go again.");
            return;
        }
    }

    System.out.println("Wait time is over, go to sleep.");
    app.timeToSleep();

however, within "timeToSleep" I now want to do things like:

Device.setFlightmodeEnabled(true); or

TaskManager.killall();

How would I achieve something like that? I have not found anything so far, but maybe I have the wrong key words to look for.

Thanks and best regards

You can access some device features via API and some via native interfaces but I don't think setting a device to flightmode is technically possible without operator or Google authorization and that's only possible on Android...
