title: What is the purpose of /drawable-v14 or /drawable-v11?
body: <p>I've seen that some Google's or other open source projects have resource directories like <code>/drawable-v14</code> or <code>/drawable-hdpi-v11</code>.</p>
  
  <p>Now, I understand what this means: all devices with SDK larger or equal than v11/v14 should use these images. </p>
  
  <p>But what is the purpose of this? Why and when should I use them? Why devices of HDPI resolution and SDK v11 should ever use images different than HDPI devices and SDK 10?</p>
  
  <p>I just cannot see when I will ever use one image for SDK 10 and another for SDK 17, for example. Makes no sense to me. </p>
  
  <p>As a side note, the usage of resources <code>/values-v{11/14/17}</code> is logical and has the practical benefit. </p>
