The notification service displays the last notification that was set , the ones before don't get displayed

Question

First of all I know that this question has been asked a lot , and the only answer is to set an unique id for the manager and the pending Intent so I did:

here's a code:

@Override
    public int onStartCommand(Intent i , int flags , int startId){


        try{

            //UnqueID = i.getExtras().getInt(PassedUNIQUEID);

            UniqueID++;

            Log.d("SERVICECHECK" , UniqueID + "");

            mStopIntent = new Intent(this , Service_reminder.class);

            sTimeUntilNotification = 0;

            CalculateTimeInMilSeconds(i);

            final String Title = i.getExtras().getString(PassedSharedPref);
            final String Note = i.getExtras().getString(PassedName);


            //


             Intent notificationIntent = new Intent(Service_reminder.this, activity_todialog_notecontent.class);
             notificationIntent.putExtra(activity_todialog_notecontent.EXTRA_SUBJECTNAME, Title);
             notificationIntent.putExtra(activity_todialog_notecontent.EXTRA_CONTENT, Note);

            PendingIntent contentIntent = PendingIntent.getActivity(Service_reminder.this, UniqueID , notificationIntent,   
                       PendingIntent.FLAG_UPDATE_CURRENT | PendingIntent.FLAG_ONE_SHOT);

             builder =  new NotificationCompat.Builder(this).setSmallIcon(R.drawable.iconsubjecttracker)
                        .setContentTitle(Title)
                        .setContentText(Note); 

            builder.setContentIntent(contentIntent);  
            builder.setAutoCancel(true);

            Uri AlarmSound = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
            builder.setSound(AlarmSound);
            manager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);  

            Log.d("SERVICECHECK" , sTimeUntilNotification + "");

            CountDownTimer Timer = new CountDownTimer(sTimeUntilNotification , 1000) {

                @Override
                public void onTick(long millisUntilFinished) {

                    //manager.notify(0, builder.build());

                }

                @Override
                public void onFinish() {

                    manager.notify(UniqueID, builder.build());
                    stopService(mStopIntent);

                }
            }.start();

        }catch(NullPointerException e){

            //handle

        }



        return START_STICKY;
    }

It fires up no problem on the time , but the problem is when for example I set a reminder " to fire notification later " on a note and for example I put 2 minutes and then I go to the next note and put a reminder with and lets say a minute then the first fires up no problem and the second fires up and then updates the first ? so the user will see the last notification that was fired , I'm not sure how to fix this.

Edit:

well I'm lost , I've been trying to solve it for hours and nothing worked , from declaring a static variable and adding 1 everytime I call the service to putting an unique id in shared prefrences and load it and then update it, but nothing worked.

I edited the code to the latest thing I did which is again putting a static variable and adding one everytime since it's the cleanest solution in my opinion.

Hopefully I can find a solution tomorrow.

for anyone not wanting to read everything here's an example + a picture for what I did:

first the picture:

http://oi62.tinypic.com/2mrs9s0.jpg

as you can see I called start service twice one with 1 minute reminder and the other with 2 minutes reminder , the 1 and 2 are the Unique id , so it couldn't have used the same id.

an example of the problem:

I have a note that says " math " for example and I put a reminder after 2 minutes , and then another note that says " calculus " and I put a reminder after 1 minute , after 1 minute the notification of calculus pops with no problem , after 2 minutes only the sound pops but not the math notification , and it stays the same as if I only put a calculus note.

Edit 2:

I've solved it after using alarm manager instead of a counter down.

Answer 1

This Method I have created in Service Class

Here SIMPLE_NOTFICATION_ID = 1

also i have tried with multiple different SIMPLE_NOTFICATION_ID and it does not remove the previous notification . means it works good.
