Android Question Error with ActionBar after 7.8 upgrade

Are you using the latest version of AppCompat?

Please try to extend from: android.support.v7.app.AppCompatActivity

android.support.v7.app.ActionBarActivity is deprecated since 2015 and maybe they have removed it from the latest Support library (though I haven't found a notice about it in the changelogs)

Try to load the layout in the designer and save it. Now compile and try again.
