Android: Concept for day-sensitive scheduled App-start (Alarm Clock)

[Flaming Moe]

Hoí there,

somehow I´m not able to find an explicit english forum for Android develoopment - which I find hard to believe to extend, I think I´m missing something...

How ever

In the scope of an individual alarm-clock app based on Qt , running on Android, I´m trying to figure out, what the approrpiate way is, to start an app at a certain time AND certain selectable days.

What does already work
I do have solved to start my app at a given time from what I found link text and in addition squeezing ChatGPT.

public class RestartNotificationClient
{
    private static AlarmManager alarmMgr;
    private static PendingIntent alarmIntent;

    //private static OverlayAppToLockScreen;

    public static void notify(Context context, int hour, int minute) {

            alarmMgr = (AlarmManager)context.getSystemService(Context.ALARM_SERVICE);
            //Intent intent = new Intent();
            //intent.setComponent(new ComponentName("org.qtproject.example.androidnotifier", "AlarmNotification"));
            Intent intent = context.getPackageManager().getLaunchIntentForPackage("org.qtproject.example.androidnotifier");

            //System.out.println(view);
            if(intent == null) System.out.println("Wrong wrong wrong wrong");
            alarmIntent = PendingIntent.getActivity(context, 0, intent, Intent.FLAG_ACTIVITY_NEW_TASK);

            Calendar calendar = Calendar.getInstance();
            calendar.setTimeInMillis(System.currentTimeMillis());
            calendar.set(Calendar.HOUR_OF_DAY, hour);
            calendar.set(Calendar.MINUTE, minute);
            alarmMgr.setExact(  AlarmManager.RTC_WAKEUP,
                                calendar.getTimeInMillis(),
                                alarmIntent);
        }
}

What I´m wondering
Since the app is an alarm-clock, it is also possible to choose the day - e.g. monday to friday out of the whole week.
How would I sensibly implement that?
Would it be like per day having a weekly scheduled alarm set - so up to 7 alarms / intents per alarm-instance?
Or is there a more clever way?
