        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_second);

        Calendar cal = Calendar.getInstance();

        service = new Intent(getBaseContext(), CapPhoto.class);
        cal.add(Calendar.SECOND, 15);
        //TAKE PHOTO EVERY 15 SECONDS
        PendingIntent pintent = PendingIntent.getService(this, 0, service, 0);
        AlarmManager alarm = (AlarmManager) getSystemService(Context.ALARM_SERVICE);

        alarm.setRepeating(AlarmManager.RTC_WAKEUP, cal.getTimeInMillis(),
                     60*60*1000, pintent);
        startService(service);

       
    }

    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        // Inflate the menu; this adds items to the action bar if it is present.
        getMenuInflater().inflate(R.menu.second, menu);
        return true;
    }

   
}
