I am on page 320 and working through two pane layouts. Unfortunately the page references and I cannot remember creating that java class. I looked through the book and can’t find a reference to it. Does anyone know where it could be? Online I have found versions of this code that extends FragmentActivity instead of AppCompatActivity.

Could someone please help me find where the SingleFragmentActivity java class was created? I am reading the 3rd edition.

Thank you!

You create that class in Chapter 8. In Listing 8.7.
