Passing extras from pending intent to the app activity

hi all, i devloped anotification that will run specific app if the user click on it, here is the code,

var activity = Ti.Android.currentActivity;
                var intent = Ti.Android.createIntent({
                    action : Ti.Android.ACTION_MAIN,
                    // you can use className or url to launch the app
                    // className and packageName can be found by looking in the build folder
                    // for example, mine looked like this
                    // build/android/gen/com/appcelerator/notify/NotifyActivity.java
                    // className : 'com.appcelerator.notify.NotifyActivity',
 
                    // if you use url, you need to make some changes to your tiapp.xml
                    url : 'app.js',
                    flags : Ti.Android.FLAG_ACTIVITY_RESET_TASK_IF_NEEDED | Ti.Android.FLAG_ACTIVITY_SINGLE_TOP
                });
                intent.addCategory(Titanium.Android.CATEGORY_LAUNCHER);
                intent.putExtra('newmessagenotification','1');
                // Create the pending intent that will launch our app when selected
                var pending = Ti.Android.createPendingIntent({
                    activity : activity,
                    intent : intent,
                    type : Ti.Android.PENDING_INTENT_FOR_ACTIVITY,
                    flags : Ti.Android.FLAG_UPDATE_CURRENT
                });
 
                // Create the notification
                var notification = Ti.Android.createNotification({
                    contentIntent : pending,
                    contentTitle : serviceTitle,
                    contentText : serviceMessage,
                    tickerText : serviceMessage,
                    // "when" will only put the timestamp on the notification and nothing else.
                    // Setting it does not show the notification in the future
                    when : new Date().getTime(),
                    icon : Ti.App.Android.R.drawable.appicon,
                    flags : Titanium.Android.ACTION_DEFAULT | Titanium.Android.FLAG_AUTO_CANCEL | Titanium.Android.FLAG_SHOW_LIGHTS,
                    defaults:Titanium.Android.NotificationManager.DEFAULT_SOUND
                });
                Ti.Android.NotificationManager.notify(1, notification);

in this code

intent.putExtra('newmessagenotification','1');

iam trying to send the extra to the app, but now i can't get any extras there... in my app i tried to put this code in the focus event of every window i have to catch the event indecating that the application is coming from a notification>

var curService = Titanium.Android.currentActivity;
var curIntent = curService.getIntent();
                var newmessagenotification = curIntent.hasExtra('newmessagenotification') ? curIntent.getStringExtra('newmessagenotification'):"0";

but the value of newmessagenotification is always "0" which means that no Extras exist in the intent.

my question is about two things, what is the vent i should listen to to catch that the application or the activity is coming from the notification,

and the second how i would send data from the notification to the app or activity,answering any question of those too will be a great help,thanks alot
