Solution 1:

we can recieve currentMonth value from source and it is an integer

if (currentMonth == Calendar.JANUARY || currentMonth == Calendar.MARCH || currentMonth == Calendar.MAY || currentMonth == Calendar.JULY 
            || currentMonth == Calendar.AUGUST || currentMonth == Calendar.OCTOBER || currentMonth == Calendar.DECEMBER){
    alarmMgr.setRepeating(AlarmManager.RTC_WAKEUP, calendar.getTimeInMillis(), AlarmManager.INTERVAL_DAY * 31, alarmIntent);
    }
    if (currentMonth == Calendar.APRIL || currentMonth == Calendar.JUNE || currentMonth == Calendar.SEPTEMBER 
            || currentMonth == Calendar.NOVEMBER){
        alarmMgr.setRepeating(AlarmManager.RTC_WAKEUP, calendar.getTimeInMillis(), AlarmManager.INTERVAL_DAY * 30, alarmIntent);
        }


    if  (currentMonth == Calendar.FEBRUARY){//for feburary month)GregorianCalendarcal= (GregorianCalendar) GregorianCalendar.getInstance();    
            if(cal.isLeapYear(year)){//for leap year feburary month  
                alarmMgr.setRepeating(AlarmManager.RTC_WAKEUP, calendar.getTimeInMillis(), AlarmManager.INTERVAL_DAY * 29, alarmIntent);
            }
            else{ //for non leap year feburary month
                alarmMgr.setRepeating(AlarmManager.RTC_WAKEUP, calendar.getTimeInMillis(), AlarmManager.INTERVAL_DAY * 28, alarmIntent);
            }
    }

Solution 2:

You should use cal.getActualMaximum(Calendar.DAY_OF_MONTH));. This gives you the maximum date for each month irrespective of the month.
