Show repeating Notification from some start Date until some end date

Question

I have many weekly-repeating events every one has a start/End dates. it should appear every week at the same day & time.

So I want to show notification for every event on every week at a specific date&time starting from it's start Date until it's end date.

Can any one provide me with a tutorial / explanation / Links on how to implement this, please?

Take a look at the official Android docs - link here.

You need to use the setRepeating function in AlarmManager to achieve this. Create a BroadcastReceiver that creates a notification when an Intent is received. Set this Intent in a PendingIntent and give the PendingIntent to the AlarmManager#setRepeating.

Example code -

private AlarmManager alarmMgr;
private PendingIntent alarmIntent;
...
alarmMgr = (AlarmManager)context.getSystemService(Context.ALARM_SERVICE);
Intent intent = new Intent(context, AlarmReceiver.class);
alarmIntent = PendingIntent.getBroadcast(context, 0, intent, 0);

// Set the alarm to start at approximately 2:00 p.m.
Calendar calendar = Calendar.getInstance();
calendar.setTimeInMillis(System.currentTimeMillis());
calendar.set(Calendar.HOUR_OF_DAY, 14);

// With setInexactRepeating(), you have to use one of the AlarmManager interval
// constants--in this case, AlarmManager.INTERVAL_DAY.
alarmMgr.setInexactRepeating(AlarmManager.RTC_WAKEUP, calendar.getTimeInMillis(),
        AlarmManager.INTERVAL_DAY, alarmIntent);
