XML : Error inflating class FontTextView by Yalantis

Im trying to use an Android component I found on Github. Using the sample project inside the repository I integrated the component into my app but everytime I run it I get the error: android.view.InflateException: Binary XML file line #8: Error inflating class com.yalantis.flip.sample.views.FontTextView. This FontTextView has been used in the sample project which runs just fine. Im not sure what im doing wrong as I have also copied and pasted their layouts. I thought my images were the problem but I used the original pictures used in the sample application and it still crashed.

Here is the text from my logcat:
