Hey this is how to set alarm on android AlarmManager to spesific date (android alarmmanager set alarm on date) I have been searching all over for this. pay attention to the value of the month!!

Calendar cal = Calendar.getInstance(TimeZone.getDefault(), Locale.getDefault());
//cal.add(Calendar.SECOND, 10);

cal.set(Calendar.DATE,19);  //1-31
cal.set(Calendar.MONTH,Calendar.DECEMBER);  //first month is 0!!! January is zero!!!
cal.set(Calendar.YEAR,2012);//year...

cal.set(Calendar.HOUR_OF_DAY, 16);  //HOUR
cal.set(Calendar.MINUTE, 39);       //MIN
cal.set(Calendar.SECOND, 10);       //SEC


// Create a new PendingIntent and add it to the AlarmManager
Intent intent = new Intent(MainActivity.this, alarmAct.class);
PendingIntent pendingIntent = PendingIntent.getService(MainActivity.this, 0,intent, 0);

//or if you start an Activity
//PendingIntent pendingIntent = PendingIntent.getActivity(MainActivity.this, 0,intent, 0);

AlarmManager am = (AlarmManager) getSystemService(Context.ALARM_SERVICE);
am.set(AlarmManager.RTC_WAKEUP, cal.getTimeInMillis(), pendingIntent);

If you want to play alarm for particular date of months suppose you want to play alarm on 11-june-2012 then you should specify like this but June is 6 month then you should specify 5 in Calender.Month.

Calendar cal=Calendar.getInstance();
cal.set(Calendar.MONTH,5);
cal.set(Calendar.YEAR,2012);
cal.set(Calendar.DAY_OF_MONTH,11);

cal.set(Calendar.HOUR_OF_DAY,16);
cal.set(Calendar.MINUTE,10);
cal.set(Calendar.SECOND,0);

Intent _myIntent = new Intent(getApplicationContext(), ReceiverClass.class);
PendingIntent _myPendingIntent = PendingIntent.getBroadcast(getApplicationContext(), 123, _myIntent, PendingIntent.FLAG_UPDATE_CURRENT|  Intent.FILL_IN_DATA);
AlarmManager _myAlarmManager = (AlarmManager)getSystemService(ALARM_SERVICE);
//_myAlarmManager.set(AlarmManager.RTC_WAKEUP, System.currentTimeMillis() + (10 * 1000), _myPendingIntent);
_myAlarmManager.set(AlarmManager.RTC_WAKEUP, cal.getTimeInMillis(), _myPendingIntent);  

Answer 4

You should call public void setRepeating (int type, long triggerAtTime, long interval, PendingIntent operation)(see here) to repeat the alarm. For example, you want to fire the alarm on 9:00 am every day, you can do :

Calendar c=Calendar.getInstance();
c.set(Calendar.HOUR_OF_DAY, 9);
c.set(Calendar.MINUTE, 0);
setRepeating(AlarmManager.RTC_WAKEUP, c.getTimeInMillis(), AlarmManager.INTERVAL_DAY,pendingIntent);

Also,set the last parameter to 0 when initilazing the PendingIntent.

PendingIntent pendingIntent = PendingIntent.getBroadcast(fridgeDetails.this, 
                        0, myIntent, 0);
