There is something called Alarm manager, you can read about that here: Alarm manager

or some kind of timer like in this example

You can use this code to schedule a repeating alarm 

AlarmManager alarmMgr;
PendingIntent alarmIntent;
alarmMgr = (AlarmManager)context.getSystemService(Context.ALARM_SERVICE);
// Set the alarm to start at 8:00 a.m.
Calendar calendar = Calendar.getInstance();
calendar.setTimeInMillis(System.currentTimeMillis());
calendar.set(Calendar.HOUR_OF_DAY, 8);
calendar.set(Calendar.MINUTE, 0);

Intent intent = new Intent(context, AlarmReceiver.class);
alarmIntent = PendingIntent.getBroadcast(context, 0, intent, 0);
// setRepeating() lets you specify a precise custom interval--in this case,
// one day.
alarmMgr.setRepeating(AlarmManager.RTC_WAKEUP, calendar.getTimeInMillis(),
AlarmManager.INTERVAL_DAY, alarmIntent);

this only set the alarm, when system fires this alarm you need to receive this in your broadcast receiver and make a notification from there i.e in this case AlarmReceiver.class

  • yes it does, but not that `setRepeating` will set inexact alarms from API LEVEL 19 as it is mentioned in docs ```Note: as of API 19, all repeating alarms are inexact. If your application needs precise delivery times then it must use one-time exact alarms, rescheduling each time as described above. Legacy applications whose targetSdkVersion is earlier than API 19 will continue to have all of their alarms, including repeating alarms, treated as exact.``` – Hamza Khan Nov 27 '19 at 05:22
