title: New created "values" folder is not visible in Android Studio
body: <p>In Android Studio, I want to create the folders <code>values-v14</code> <code>values-v21</code> inside the <code>res</code> folder. </p>
  
  <p>But when I tried to make it like: right click on <code>res</code> folder select option <code>New &gt;Directory</code>, then after creating the folder, it is not visible in Android Studio. But when I select the option <code>Show in Explorer</code>, then it is visible. </p>
  
  <p>How do I create a folder in Android Studio, so that I can change files like <code>styles.xml</code>, etc?</p>
