title: Android Studio - how was this resource file structure trick achieved?
body: <p>I was checking out the Google I/O app source code in Android studio, and I came across this IDE layout of the <code>res/</code> folder - how was this achieved?</p>
  
  <p>But if I look at my filesystem at the actual file structure, it's the conventional <code>values/styles.xml</code>, <code>values-v17/styles.xml</code>, <code>values-v21/styles.xml</code> arrangement. How can I achieve this in my own app?</p>
