Unable to resolve superclass of FragmentActivity

I had my environment setup on a previous machine, and I'm on a differnt MacBook. For some strange reason, I keep getting an issue with one of my classes which exend FragmentActivity. It keeps saying it can't find the FragmentActivity class, although I have the support jar in my class path, as per the image:

enter image description here

The detailed error message that I'm seeing is here:

In your IDE (as shown in your screenshot), check the 'export' box next to the classpath entry that contains the missing class.

I had a similar problem with a class from the Android Support library (Unable to resolve superclass of Lcom ... PagerAdapter). It turned out a library referenced in the .classpath needed to be exported:

From:

<classpathentry

To:

<classpathentry exported="true" ...

For Eclipse users, I fixed the problem by exporting Android Private Libraries in the Java Build Path menu.

Checking Android Private Libraries in Eclipse Kepler Java Build Path.
