alarmManager not properly set after restart

问题:

I want to get a notification every day (at 13:00) with alarmManager, but when the device is restarted, the alarm is active for one day only and does not work for 2nd or 3rd day unless I run my application.

Why does it run only once?

MainActivity.class:

public class MainActivity extends ActionBarActivity implements OnClickListener 
{
   super.onCreate(savedInstanceState);
   setContentView(R.layout.activity_main);

   alarmKurulum();
}



public void alarmKurulum() {
    Intent alarmIntent = new Intent(MainActivity.this, AlarmReceiver.class);
    PendingIntent pendingIntent = PendingIntent.getBroadcast(MainActivity.this, 0, alarmIntent, 0);

    AlarmManager alarmManager = (AlarmManager) getSystemService(ALARM_SERVICE);

    Calendar alarmStartTime = Calendar.getInstance();

    alarmStartTime.set(Calendar.HOUR_OF_DAY, 18);
    alarmStartTime.set(Calendar.MINUTE, 05);
    alarmStartTime.set(Calendar.SECOND, 00);
    alarmStartTime.set(Calendar.MILLISECOND, 0);

    Calendar now = Calendar.getInstance();

    if(alarmStartTime.getTimeInMillis() < now.getTimeInMillis()) {
        alarmStartTime.setTimeInMillis(alarmStartTime.getTimeInMillis() + 86400000);
    }

    alarmManager.set(AlarmManager.RTC_WAKEUP, alarmStartTime.getTimeInMillis(), pendingIntent);
}

AlarmReceiver.class:

public class AlarmReceiver extends BroadcastReceiver {
    @Override
    public void onReceive(Context context, Intent intent) {
        Intent service1 = new Intent(context, AlarmService.class);
        context.startService(service1); 
    }
}

TurnonAlarm.class (for reboot device)

public class TurnOnAlarmReceive extends BroadcastReceiver {

    @Override
    public void onReceive(Context context, Intent intent) {
        if (intent.getAction().equals("android.intent.action.BOOT_COMPLETED")) {
            Intent alarmIntent = new Intent(context, AlarmReceiver.class);
            PendingIntent pendingIntent = PendingIntent.getBroadcast(context, 0, alarmIntent, 0);

            AlarmManager alarmManager = (AlarmManager) context.getSystemService(Context.ALARM_SERVICE);

            Calendar alarmStartTime = Calendar.getInstance();

            alarmStartTime.set(Calendar.HOUR_OF_DAY, 18);
            alarmStartTime.set(Calendar.MINUTE, 05);
            alarmStartTime.set(Calendar.SECOND, 00);
            alarmStartTime.set(Calendar.MILLISECOND, 0);


            Calendar now = Calendar.getInstance();

            if(alarmStartTime.getTimeInMillis() < now.getTimeInMillis()) {
                alarmStartTime.setTimeInMillis(alarmStartTime.getTimeInMillis() + 86400000);
            }
            alarmManager.set(AlarmManager.RTC_WAKEUP, alarmStartTime.getTimeInMillis(), pendingIntent);         
        }
    }
}
