title: Android Maven project using Volley: NullPointerException
body: <p>I've got a Maven project that I'm trying to use Volley with. This is my first time using either. I added Volley to my local repository, and I added the dependency in my project's pom.xml file. Everything compiles nicely, but whenever I try to make a new Request object, I get a NullPointerException on the super class Request object. Any help?</p>
  
  <p>EDIT: Here's my stack trace</p>
