Set alarm for several days

I'm working on alarm clock app. I've faced with one problem. I do not know how to set alarm for several days. I've already tried the code that is below but in log I saw this Wed Apr 06(didn't change any date so it should be nearest tuesday and friday). What do I do wrong? May be I should set alarm separately for every other day?

This is my code:

calendar.set(Calendar.DAY_OF_WEEK, Calendar.TUESDAY, Calendar.FRIDAY);
                //calendar.add(Calendar.DAY_OF_WEEK,Calendar.FRIDAY);
                Log.e("Point_1","Calendar " + calendar.getTime());
                calendar.set(Calendar.HOUR_OF_DAY,timePicker.getCurrentHour());
                calendar.set(Calendar.MINUTE,timePicker.getCurrentMinute());
                Intent intent1 = new Intent(MyService_alarm.this,MyReceiver_Alarm.class);
                PendingIntent pendingIntent = PendingIntent.getBroadcast(MyService_alarm.this,intent.getIntExtra("Size", 1),intent1,0);
                AlarmManager alarmManager = (AlarmManager) getSystemService(ALARM_SERVICE);
                alarmManager.setRepeating(AlarmManager.RTC, calendar.getTimeInMillis(), 7 * 24 * 3600 * 1000, pendingIntent);

Thank you.

The line

calendar.set(Calendar.DAY_OF_WEEK, Calendar.TUESDAY, Calendar.FRIDAY);

is not correct. If you look at the documentation you will see that there is no such method.

By writing Calendar.DAY_OF_WEEK you are telling system that you are entering some value as day of the week. But instead of one specific day you are entering two. Calendar object is used to store one specific date.

Therefore, in order to get set alarms for several days, you need to set each of the alarms separately. For this reason you may create separate Calendar objects or reuse one by changing the time. However, you have same receiver class for both alarms. Therefore, you need to create different pending intents to make alarm manager differentiate them. For this reason I have shown you the example with different request_code.

calendar1.set(Calendar.DAY_OF_WEEK, Calendar.TUESDAY);
calendar2.set(Calendar.DAY_OF_WEEK, Calendar.FRIDAY);

calendar1.set(Calendar.HOUR_OF_DAY, timePicker.getCurrentHour());
calendar1.set(Calendar.MINUTE, timePicker.getCurrentMinute());

calendar2.set(Calendar.HOUR_OF_DAY, timePicker.getCurrentHour());
calendar2.set(Calendar.MINUTE, timePicker.getCurrentMinute());

Intent intent1 = new Intent(MyService_alarm.this, MyReceiver_Alarm.class);
PendingIntent pendingIntent1 = PendingIntent.getBroadcast(MyService_alarm.this, 1, intent1, 0);
PendingIntent pendingIntent2 = PendingIntent.getBroadcast(MyService_alarm.this, 2, intent1, 0);

AlarmManager alarmManager = (AlarmManager) getSystemService(ALARM_SERVICE);
alarmManager.setRepeating(AlarmManager.RTC, calendar1.getTimeInMillis(), 7 * 24 * 3600 * 1000, pendingIntent1);
alarmManager.setRepeating(AlarmManager.RTC, calendar2.getTimeInMillis(), 7 * 24 * 3600 * 1000, pendingIntent2);

That is because you are logging the time before setting the hour and minutes from the time picker,

your code si working fine but to display the time that was set to the Alarm in your log you have to move the Log.e to after you set the Calendar to the hour and minute from your picker so your code should look like this :

calendar.set(Calendar.DAY_OF_WEEK, Calendar.TUESDAY, Calendar.FRIDAY);
            //calendar.add(Calendar.DAY_OF_WEEK,Calendar.FRIDAY);
            calendar.set(Calendar.HOUR_OF_DAY,timePicker.getCurrentHour());
            calendar.set(Calendar.MINUTE,timePicker.getCurrentMinute());
            Log.e("Point_1","Calendar " + calendar.getTime());
            Intent intent1 = new Intent(MyService_alarm.this,MyReceiver_Alarm.class);
            PendingIntent pendingIntent = PendingIntent.getBroadcast(MyService_alarm.this,intent.getIntExtra("Size", 1),intent1,0);
            AlarmManager alarmManager = (AlarmManager) getSystemService(ALARM_SERVICE);
            alarmManager.setRepeating(AlarmManager.RTC, calendar.getTimeInMillis(), 7 * 24 * 3600 * 1000, pendingIntent);

Also since you are making an Alarm for several days it would be wise to save all the set alarms and to add a receiver to detect when the device has been booted since your alarms are cancelled on reboot and will need to be added again.
