Android pending intent notification problem

androidandroid-intentnotifications

I have a alarm thing going on in my app and it launches a notification that then when pressed launched an activity.
The problem is that when I create more than one alarm then the activity launched from the notification gets the same extras as the first one. I think the problem is either with the intent i put in the pending intent or in the pending intent itself. I think I might need to put a flag on one of these but I dont know which one.

Intent showIntent =new Intent(context, notificationreceiver.class);
    showIntent.putExtra("details", alarmname);

PendingIntent contentIntent = PendingIntent.getActivity(context, 0,
        showIntent, 0); 

    notification.setLatestEventInfo(context, "The event is imminent",
            alarmname, contentIntent);

And the receiver of the notification

Bundle b = getIntent().getExtras();
    String eventname = b.getString("details");
    details.setText(eventname);

The "details" extra is the same to every the next time a notification happens instead of having the different value.
Until I set the intents I am sure that the correct value goes to the "details" so its a problem of getting the first intent everytime i press any notification.
How can I make it to launch the correct intents?
Hope I was as clear as i could
Thanks!

The way I solved that problem was by assigning a unique requestCode when you get the PendingIntent:

PendingIntent.getActivity(context, requestCode, showIntent, 0); 

By doing so you are registering with the system different/unique intent instances. Tip: A good way of making the requestCode unique would be by passing to it the current system time.

int requestID = (int) System.currentTimeMillis();
