android - How to set click listener for notification?

Question

I am using the following code to launch a notification when a Service is started Via AlarmManager:

nm = (NotificationManager) this.getSystemService(Context.NOTIFICATION_SERVICE);
CharSequence from = "App";
CharSequence message = "Getting Latest Info...";
PendingIntent contentIntent = PendingIntent.getActivity(this, 0, new Intent(), 0);
Notification notif = new Notification(R.drawable.icon,
    "Getting Latest Info...", System.currentTimeMillis());
notif.setLatestEventInfo(this, from, message, contentIntent);
nm.notify(1, notif);

How do I set an intent for this item so that when the user clicks on it, it would launch a certain activity?

As for yoshi24's comment, you may be able to set extras like this.

final Intent intent = new Intent(this, MyActivity.class);
intent.setData(data);
intent.putExtra("key", "value");
final PendingIntent contentIntent = PendingIntent.getActivity(this, 0, intent, 0);

You need to be aware of this as well before going for pending intents

UPDATE some thing like this will work for you

int your mainfest

<activity android:name=".MyActivity" android:launchMode="singleTop" ... />

in your activity

@Override
protected void onCreate(Bundle savedInstanceState) {
    processIntent(getIntent());
}

@Override
protected void onNewIntent(Intent intent) {     
    processIntent(intent);
};

private void processIntent(Intent intent){
    //get your extras
}
