Question

I’m having an issue with the Facebook graph API not returning anything for a request to get a user’s notifications. I’m doing it through a batch request, using the same syntax to get a user’s news feed, and the news feed request works fine. I have the “manage_notifications” permission enabled also. I always get a null pointer exception in my code when I try to parse the result of the graph call to notifications.

Note that when I got to the graph explorer in my internet browser and type “me/notifications?include_read=true” I DO get the appropriate data.

Here’s the code for my request.

static Request notificationsRequest = Request.newGraphPathRequest(fbSession, "me/notifications?include_read=true", new Request.Callback() {

    @Override
    public void onCompleted(Response response) {
        GraphObject object = response.getGraphObject();
        if(object != null){
            notifications = object.getProperty("data").toString();
        }
        else{
            notifications = "Notifications returns null";
        }

    }
});

Any ideas? Thanks.

EDIT: I updated the code and found out that the GraphObject object is returning null and that’s why it can’t parse anything from it. It seems like there would be something wrong with the graph request, but I can’t figure out what it is. Like I said, the exact same method for getting a user’s news feed (“me/home”) works perfectly fine.

Instead of passing the parameter in the Graph path, add it as a parameter to the request:

me/notifications?include_read=true

static Request notificationsRequest = Request.newGraphPathRequest(fbSession, "me/notifications", new Request.Callback() {

    @Override
    public void onCompleted(Response response) {
        GraphObject object = response.getGraphObject();
        if(object != null){
            notifications = object.getProperty("data").toString();
        }
        else{
            notifications = "Notifications returns null";
        }

    }
});


Bundle params = new Bundle();
params.putString("include_read", "true");

notificationsRequest.setParameters(params);
