Question

I m using the alarm manager in my app and i want to repeat alarm after one day. the alarm should be invoked after one day when invoked once by time.Please help.
Thanks in advance.

if(str_freqSchedule.equals(checkForDaily)){
            Calendar calendar = Calendar.getInstance();
            //calendar.set(Calendar.DAY_OF_YEAR, calendar.get(Calendar.DAY_OF_YEAR));
            calendar.set(Calendar.HOUR_OF_DAY, hr);
            calendar.set(Calendar.MINUTE, min);
            calendar.set(Calendar.SECOND,0);

            Intent intent = new Intent(this, AlarmReceiverActivity.class);
            PendingIntent pendingIntent = PendingIntent.getBroadcast(
                    this.getApplicationContext(), j, intent, PendingIntent.FLAG_CANCEL_CURRENT);
            AlarmManager alarmManager = (AlarmManager) getSystemService(ALARM_SERVICE); 
            alarmManager.setRepeating(AlarmManager.RTC_WAKEUP, calendar.getTimeInMillis(),(24*60*60*1000),pendingIntent);
            j++;

        }

Hopefully below code will help, I used the same in my app. Here the argument passed in AlarmManager class for repeating should be 24*60*60*1000

AlarmManager am = (AlarmManager) ct.getSystemService(Context.ALARM_SERVICE);         
Intent intent1 = new Intent(ct, TimeAlarm.class);
PendingIntent pendingIntent = PendingIntent.getBroadcast(ct, 0,intent1, PendingIntent.FLAG_CANCEL_CURRENT);

Date curr=new Date();
curr.setHours(h);
curr.setMinutes(m);
c.setTime(curr);
c.set(Calendar.SECOND, 0);

Calendar c1 = Calendar.getInstance();
am.setRepeating(AlarmManager.RTC_WAKEUP, c.getTimeInMillis(),24*60*60*1000, pendingIntent);
