Inbox Fragment causes error

When I change the return of the Fragment method to InboxFragment, i get an error :

public Fragment getItem(int position) {
    // getItem is called to instantiate the fragment for the given page.
    // Return a PlaceholderFragment (defined as a static inner class
    // below).
    return InboxFragment();
}

I get the message "The method InboxFragment() is undefined for the type SectionsPagerAdapter.

I get the quick fix available Create method InboxFragment()

Also, I noticed that on the lesson, Ben has only android-support-v4.jar. In my libs, I have that version and also android-support-v13.jar.

Have tried deleting the v13.jar, but after deleting it, I got many errors.

The project worked find up until now.

Anyone have any ideas what I can do?

I dont remember the exact part of the project your having a problem with but I would say just from looking at your code you probably want to return a new instance/object of the InboxFragment class.. so add the word "new".. your return statement would look like .. return new InboxFragment();

Thank you Joe,

I just restarted the project. Found that I used the wrong Type to start off with.
