Call this function where you need:

private void setDailyNotification(int ID, int hh, int mm, int ss) {
    AlarmManager alarmManager = (AlarmManager) getSystemService(ALARM_SERVICE);
    Intent alarmIntent = new Intent(Dashboard.this, MyDailyReceiver.class);
    alarmIntent.putExtra("ID", ID);
    Log.d("setDailyNotification", "ID:" + ID);
    PendingIntent pendingIntent = PendingIntent.getBroadcast(
            Dashboard.this, ID, alarmIntent,
            PendingIntent.FLAG_UPDATE_CURRENT);
    mEverydayPendingIntent = pendingIntent;

    Calendar calendar = Calendar.getInstance();
    Calendar now = Calendar.getInstance();
    calendar.set(Calendar.HOUR_OF_DAY, hh);
    calendar.set(Calendar.MINUTE, mm);
    calendar.set(Calendar.SECOND, ss);

    // check whether the time is earlier than current time. If so, set it to
    // tomorrow. Otherwise, all alarms for earlier time will fire

    if (calendar.before(now)) {
        calendar.add(Calendar.DATE, 1);
    }
    alarmManager.setRepeating(AlarmManager.RTC_WAKEUP,
            calendar.getTimeInMillis(), AlarmManager.INTERVAL_DAY,
            mEverydayPendingIntent);
    Log.d("setRepeated", "ID:" + ID);

}

Broadcast receiver:

NotificationCompat.Builder mBuilder = new NotificationCompat.Builder(
                context);
        mBuilder.setContentTitle("Daily Summery");
        mBuilder.setContentText("Today's Transaction");
        mBuilder.setSmallIcon(R.drawable.app_icon);
        Log.d("tag1234", "In if" + daily_Reminder);
        NotificationCompat.InboxStyle inboxStyle = new NotificationCompat.InboxStyle();
        mBuilder.setStyle(inboxStyle);
        mNotificationMa = (NotificationManager) context
                .getSystemService(Context.NOTIFICATION_SERVICE);
        mNotificationMa.notify(11, mBuilder.build());

call function like this:

setDailyNotification(11, 11,00, 00);
