Android Extendedcalendarview Resource Not Found Error

after importing the extended calendar view for android into my android project, the xml file for my activity does not seem to load the extendedcalendarview into design view of my activity. After looking around, I found out that maybe I might have made a mistake importing the project, but I dont think that is the issue, as I believe I followed all of the correct steps. Here is the error:

Rendering problems with Android Studio after getting Android N SDK [duplicate]

This question already has answers here:
XML Rendering errors Android preview N
(4 answers)
Closed 6 years ago.
I got the Android N SDK and ever since Android Studio has been having problems rendering Views from the design library. I have tried changing the Android version used to render the layouts to Marshmallow cause I read that N as issues but it keeps saying rendering problems.

This is how it is rendering the layout when marshmallow is selected as the version to render layout:

Make sure that you downloaded Android N in the SDK Manager. You can find the SDK manager next to the purple phone/android (at the top menu bar).
And then, set targetto 24.
