You have to make sure that when you extend Fragment that you are extending the Fragment that is in the v4 package space. Check your imports for Fragment, FragmentActivity, etc, and if you see them imported WITHOUT .v4 in the package name, then it is wrong.

Also, if you set the android library for the project to be 2.3 and not 4.0.x then you'll quickly see if you are using the incorrect classes, because you'll get compile errors, which can be fixed by using the v4 classes from the android support jar (which hopefully you've included in your project as well)
