InflateException

I've been encountering and InflateException error and am not really sure what it means. I hope someone can explain it to me. Thanks. Below is the stack trace.

It seems you want to set a layout in your onCreate() method using setContentView(). The layout refers to a class in line #5 that is named com.project.something.something.android. I guess the class doesn't exist and so the layout couldn't be inflated.
