android - Preserve back activity while clicking notification

Question

My problem is like that: When I'm pressing the notification i got, some activity is open, lets say activity number 3. But when I press the back button, I navigated by the android to the menu. What I want to do is to preserve the correct navigation experience of the user, and when I'm pressing the back button it will take me to activity number 2, and when I'm pressing there on the back button, it will take me to activity number 1, and so on.
Another problem I have is that, when I'm opening activity number 2, I need to set there some extra data in the intent, but I don't know how to set it.
Summery of my problem: preserve the correct navigation of the user and set some extras for the activity that will be open by the back button click.

Here is my notification code:

NotificationCompat.Builder mBuilder =
                new NotificationCompat.Builder(this)
                .setSmallIcon(R.drawable.ic_launcher)
                .setContentTitle("New Question")
                .setContentText("" + CurrentQuestion.getAuthor().getUserName() + ": " + CurrentQuestion.getQuestion() + "");

        Intent openHomePageActivity = new Intent("com.example.ihelp.HOMEPAGEACTIVITY");
        TaskStackBuilder stackBuilder = TaskStackBuilder.create(this);
        stackBuilder.addNextIntent(openHomePageActivity);
        PendingIntent resultPendingIntent =
                stackBuilder.getPendingIntent(
                    0,
                    PendingIntent.FLAG_UPDATE_CURRENT
                );
        mBuilder.setContentIntent(resultPendingIntent);
        NotificationManager mNotificationManager =
            (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
        mNotificationManager.notify(0, mBuilder.build());

Thanks!

Looks like you want to synthesize a back stack: http://developer.android.com/training/implementing-navigation/temporal.html#SynthesizeBackStack (see "Create back stack when starting the activity")

and also http://developer.android.com/guide/topics/ui/notifiers/notifications.html#NotificationResponse ("Preserving Navigation when Starting an Activity" as a "Regular activity")
