AlarmManager manager = (AlarmManager) getSystemService(ALARM_SERVICE);

        Intent intent = new Intent(EditTextViewDemoActivity.this, AlarmTest.class);

        PendingIntent operation = PendingIntent.getActivity(this, 0, intent, 0);

        Calendar calendar = Calendar.getInstance();

        calendar.setTimeInMillis(System.currentTimeMillis());

        calendar.add(Calendar.SECOND, 15);

        manager.set(0, calendar.getTimeInMillis(), operation);
