Многообразные Извещения только покажи последнюю, он не становится отвечающим современным требованиям

Что я должен делать для того, чтобы, когда мое приложение пошлет секунду (третья. четверть... и т.д.) извещение не было заменено, и включились все?

MainActivity.java:

public class MainActivity extends ActionBarActivity {

    DatePicker datePicker;
    TimePicker timePicker;
    Button btnStart;
    Uri uriAlarm;
    final static int RQS_1 = 1;
    EditText textonombre;
    EditText textodescripcion;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.notif_main);

        datePicker = (DatePicker)findViewById(R.id.datepicker);
        timePicker = (TimePicker)findViewById(R.id.timepicker);
        btnStart = (Button)findViewById(R.id.start);
        uriAlarm = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_ALARM);
        textonombre = (EditText)findViewById(R.id.textonombre);
        textodescripcion = (EditText)findViewById(R.id.textodescripcion);



        btnStart.setOnClickListener(new OnClickListener() {
            @Override
            public void onClick(View v) {
                    setAlarm(uriAlarm);
                    Toast.makeText(MainActivity.this, "Alarma ACTIVADA", Toast.LENGTH_SHORT).show();
                }
        });
    }

    private void setAlarm(Uri passuri){

        Calendar cal = Calendar.getInstance();
        cal.set(datePicker.getYear(),
                datePicker.getMonth(),
                datePicker.getDayOfMonth(),
                timePicker.getCurrentHour(),
                timePicker.getCurrentMinute(),
                00);
        Intent intent = new Intent(getBaseContext(), pruebaintento.dos.notif.AlarmReceiver.class);
        PendingIntent pendingIntent = PendingIntent.getBroadcast(
                getBaseContext(),
                RQS_1,
                intent,
                PendingIntent.FLAG_CANCEL_CURRENT);

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

    }
}

AlarmReceiver.java

public class AlarmReceiver extends BroadcastReceiver {

    @Override
    public void onReceive(Context context, Intent intent) {

        NotificationManager notificationManager = (NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE);

        Intent repeating_intent = new Intent(context,MainActivity.class);
        repeating_intent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);


        PendingIntent pendingIntent = PendingIntent.getActivity(context,id,repeating_intent, PendingIntent.FLAG_UPDATE_CURRENT);


        NotificationCompat.Builder builder = (NotificationCompat.Builder) new NotificationCompat.Builder(context)
                .setContentIntent(pendingIntent)
                .setSmallIcon(R.drawable.ic_launcher)
                .setContentTitle("NOMBRE")
                .setContentText("DESCRIPCIÓN")
                .setAutoCancel(true);
        notificationManager.notify(id,builder.build());

    }
}

Я издаю: @Elenasys

public class AlarmReceiver extends BroadcastReceiver {

    int id= 1;

    @Override
    public void onReceive(Context context, Intent intent) {



        NotificationManager notificationManager = (NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE);

        Intent repeating_intent = new Intent(context,MainActivity.class);
        repeating_intent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);


        PendingIntent pendingIntent = PendingIntent.getActivity(context,id++,repeating_intent, PendingIntent.FLAG_UPDATE_CURRENT);


        NotificationCompat.Builder builder = (NotificationCompat.Builder) new NotificationCompat.Builder(context)
                .setContentIntent(pendingIntent)
                .setSmallIcon(R.drawable.ic_launcher)
                .setContentTitle("NOMBRE")
                .setContentText("DESCRIPCIÓN")
                .setAutoCancel(true);
        notificationManager.notify(id++,builder.build());

    }
