I'm getting the following NPE when Android Studio tries to render the layout in its Preview.
Maybe some initialization should be done if isInEditMode.

@jush Is your problem indeed fixed? I have the same issue and updating to 1.0.1 has not fixed it. Here's what I get

@SaifurRahmanMohsin Yes, it's fixed. I had to rebuild the project (in Android studio go to menu "Build -> Rebuild Project")

Ah I did rebuild it. Alright, thanks for the info. I will have to dig into my project to see why it still appears, something else might be wrong.
Thank you very much!
