title: Add android-numberpicker backport to Android Studio Gradle project
body: <p>I want to use this library in my Android Studio project <a href="https://github.com/SimonVT/android-numberpicker" rel="nofollow">https://github.com/SimonVT/android-numberpicker</a>. I can't for the life of me figure out how to add it to my project. Can someone just outline how this would work? I've only ever added libraries that were contained in jar files.</p>
