Please read the readme part about theming and define the attributes:

Theming

The library supports a dark and a light theme out-of-the-box. In order to do that, it defines a couple of custom attributes in attrs.xml. To integrate the contact picker in your app, you need to either extend one of the contact picker themes (ContactPicker_Theme_Light / ContactPicker_Theme_Dark) or define the custom attributes in your own theme.
