Question

In general, when i have notification message on the notification bar and click on it. It open the registered App for that message.

On Startup’s Activity, How to determine if App is open from it?

and more better is How to retrieve the notification’s id on the OnCreate() method?

Update: from @Ovidiu – here is my code to putExtra to push

       Notification notification = new Notification(icon, tickerText, System.currentTimeMillis());
       notification.contentView = contentView;

       Intent notificationIntent = new Intent(this, Startup.class);
       notificationIntent.putExtra("JOBID", jobId);

       PendingIntent contentIntent = PendingIntent.getActivity(this, 0, notificationIntent, PendingIntent.FLAG_ONE_SHOT);

       notification.flags = Notification.FLAG_AUTO_CANCEL;
       notification.contentIntent = contentIntent;


       mNotificationManager.notify(jobId, notification);

and on Main Activity “Startup.java” code is

    Intent intent = this.getIntent();
    if (intent != null && intent.getExtras() != null && intent.getExtras().containsKey("JOBID")) {
        int jobID = this.getIntent().getExtras().getInt("JOBID");

        if (jobID > 0) {

        }
    }

intent.getExtras() always return null. Turn out, I need to pass PendingIntent.FLAG_ONE_SHOT . It is now passed along!!

You need to use putExtra(ID_KEY,id) when you create your Intent for starting your application, and in your onCreate() method you can use getIntent().getExtras().getInt(ID_KEY); to retrieve your passed id integer.
