Are you using an API lvl higher than Lvl 11? The Fragment was added since Lvl 11.

The StackTrace shows that it tries loading the class 'android.view.fragment' But the Fragment class is located at 'android.app.Fragment', so something is really wrong.

Something might be wrong with you .xml layout files. Or the SDK version you are developping on is an old one.

For better analysis pls post some more code (.xml files and .java files)

See the docs : http://developer.android.com/reference/android/app/Fragment.html
