title: Use library without gradle files in Android Studio
body: <p>I am trying to import this library my Android Studio project, but am not having any luck because it doesn't have any gradle files. <a href="https://github.com/xibsked/android-numberpicker" rel="nofollow noreferrer">https://github.com/xibsked/android-numberpicker</a></p>
  
  <p>I found these posts, (<a href="https://stackoverflow.com/questions/25454998/using-library-products-without-gradle-files-in-android-studio">Using library products without gradle files in Android Studio</a>, <a href="https://stackoverflow.com/questions/30430356/how-to-import-project-files-without-gradle-files-into-android-studio">How to import project files without Gradle files into Android Studio</a>) but they are either unanswered or the answers involve exporting from Eclipse, which isn't my case. I'm not migrating from Eclipse, just want to use this library. </p>
  
  <p>Thanks!</p>
