I am new to Android. I have been working thru some examples in a book called Head First Android Development. I entered a small program using fragments and get a Casting Error.
cannot cast andoid.app.fragment to com.hilights.rsobol.workout.WorkoutDetailFragment
I am hoping someone can download the attached zip file and show me the error of my ways. It is most likely a simple error that someone with some experience can see.
Thank you in advance for your help,
