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?

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

    Not all versions of Android require this. I had a case that was working fine on everything except the Kindle Fire. – Ed Burnette Jun 18 '12 at 20:54

    Do you know what I do if I don't want any intent to fire on clicking the notification? I just want it to be there whilst the system is doing something and it will go on its own. – Richard Green Oct 24 '12 at 02:23
  • for my case, showing notificationBar from Service, that would be mBuilder.setContentIntent(PendingIntent.getActivity(this, 0, new Intent(), 0)); – toantran Nov 15 '13 at 06:43

    Interestingly the docs specify that 3 things are required, but the contentIntent is not one of them. http://developer.android.com/guide/topics/ui/notifiers/notifications.html – Richard Fung Jun 18 '14 at 23:21

I think this is because the Android OS Version

The version 2.3 or lower,must set contentIntent,if not,you will get this Exception.

In my project,I write like this:

 if (android.os.Build.VERSION.SDK_INT < android.os.Build.VERSION_CODES.HONEYCOMB) { 
     Intent intent = new Intent();
     PendingIntent contentIntent = PendingIntent.getActivity(context, 0, intent, 0); 
     mNotification.contentIntent = contentIntent; 
 }

Perhaps this could help you!

In your case

contentIntent = PendingIntent.getActivity(this, 0, notificationIntent,0);

if you want to use Intents with the same action but different extras:

  1. Change requestCode from default "0" in

    getActivity(Context context, int requestCode, Intent intent, int flags)

to something unique like

(int) System.currentTimeMillis();

notification.contentIntent = notificationIntent;

Both steps are mandatory because:

  • Option 2 will not work without option 1.
  • Option 1 will throw IllegalArgumentException without 2.

In my case, I had an example code to do, with a single Notification to create, and I also got "contentIntent required" error - google brought me to this thread :D

the source of this problem were quotations that I copied from an example code and pasted it in eclipse project. When I deleted " " and typed them back and problem was solved. Maybe this helps someone.

These were quotations source of error: nb.setContentTitle("My first notification!"); nb.setContentText("Hello");
