The next step is to display the labels of these activities in NerdLauncherFragment’s RecyclerView. An

NerdLauncherFragment’s -> NerdLauncherActivity’s

Thanks.

Chapter 21 Styles and Themes
Styles section

<style name="BeatBoxButton">
    <item name="android:background">@color/dark_blue</item>
</style>

Should be below depending on which API you choose (21 or newer, I believe)

<style name="BeatBoxButton">
    <item name="android:backgroundTint">@color/dark_blue</item>
</style>
