Alarm repeating only on weekdays

Question

Calendar calendar = Calendar.getInstance();

            calendar.set(Calendar.DAY_OF_WEEK, Calendar.MONDAY); // Tue, Wed... 
            calendar.set(Calendar.HOUR_OF_DAY, 1);
            calendar.set(Calendar.MINUTE, 0);
            calendar.set(Calendar.SECOND, 0);
            PendingIntent pi = PendingIntent.getService(context, 0, new Intent(context,MyClass.class),PendingIntent.FLAG_UPDATE_CURRENT);
            AlarmManager am = (AlarmManager) context.getSystemService(Context.ALARM_SERVICE);
            am.setRepeating(AlarmManager.RTC_WAKEUP, calendar.getTimeInMillis(), 7*24*60*60*1000, pi);

this will fire once a week at monday but: I would like to set pending alarm intent only at weekdays (without saturday and sunday), how to do it only by using one intent ? I don't want to use 5 different PendingIntents with 5 different ID's, because then I have to cancel 5

Maybe:

Create setAlarm method:

public void setAlarm(long interval){ 
    Calendar calendar = Calendar.getInstance();

    //Alarm will go off at 1
    calendar.set(Calendar.HOUR_OF_DAY, 1);
    calendar.set(Calendar.MINUTE, 0);
    calendar.set(Calendar.SECOND, 0);

    PendingIntent pi = PendingIntent.getService(context, 0, new Intent(context,MyClass.class),PendingIntent.FLAG_UPDATE_CURRENT);
    AlarmManager am = (AlarmManager) context.getSystemService(Context.ALARM_SERVICE);
    am.setRepeating(AlarmManager.RTC_WAKEUP, calendar.getTimeInMillis(), interval, pi); 
}

Create cancelAlarm method (optional, if you want to use it somewhere):

public void cancelAlarm(Context context){
    PendingIntent pi = PendingIntent.getService(context, 0, new Intent(context,MyClass.class),PendingIntent.FLAG_UPDATE_CURRENT);
    AlarmManager am = (AlarmManager) context.getSystemService(Context.ALARM_SERVICE);
    am.cancel(pi);
}

check the day in your onReceive()

@Override
public void onReceive(Context context, Intent intent) {

    Calendar calendar = Calendar.getInstance();
    int day = calendar.get(Calendar.DAY_OF_WEEK); //Sunday = 1, Saterday = 7
    switch(day){

        case 6:  //Friday
            long interval = 3*24*60*60*1000 //skip saterday and sunday
            setAlarm(interval);

        case 2: //Monday
            setAlarm(AlarmManager.INTERVAL_DAY);  //Alarm will repeat everyday, until friday
        break;
}

PS: Don't forget to set your alarm somewhere for the first time using: setAlarm(AlarmManager.INTERVAL_DAY);

I think this should work.
