Android - java.lang.IllegalArgumentException: contentIntent required error caused by notification?

Question

I have a service running that updates a notification in the notification bar when it recieves a message saying it has to be changed.

However I get the following error sometimes when the notification is to be updated

java.lang.IllegalArgumentException: contentIntent required

Here is my code:

Variable setup

---

int icon = R.drawable.notification;
CharSequence tickerText = "Test";
long when = System.currentTimeMillis();
PendingIntent contentIntent;

Notification notification = new Notification(icon, tickerText, when);

NotificationManager mNotificationManager;

---

NotificationManager Creation

---

    String ns = Context.NOTIFICATION_SERVICE;
    mNotificationManager = (NotificationManager) getSystemService(ns);

---

Notification Creation

---

    Intent notificationIntent = new Intent(this, TestsApp.class);
    contentIntent = PendingIntent.getActivity(this, 0, notificationIntent, 0);
    notification.flags |= Notification.FLAG_NO_CLEAR;
    notification.icon = R.drawable.notification3;
    notification.setLatestEventInfo(this, "Registering", "Test", contentIntent);
    mNotificationManager.notify(1, notification);

---

Update of Notification

---

    notification.icon = R.drawable.notification2;
    notification.setLatestEventInfo(getApplicationContext(), "Registered", "Test", contentIntent);
    mNotificationManager.notify(1, notification);   

---

So something is happening my contentIntent somewhere along the line, would that be correct?

It is declared at the top of my Service class as a member variable and is not used anywhere else in the code apart from shown above, so where could it be getting reset to null?

Answer 1

you need to set the contentIntent for your notification.

in your case:

notification.contentIntent = notificationIntent;

otherwise you will get the message, that the contentIntent of the notification is null, because it's not set.

the docu is here: http://developer.android.com/reference/android/app/Notification.html#contentIntent

i have a little example here: http://united-coders.com/nico-heid/show-progressbar-in-notification-area-like-google-does-when-downloading-from-android
