title: layout preview in android studio while working with mipmap
body: <p>I have read this article on <a href="http://android-developers.blogspot.in/2014/10/getting-your-apps-ready-for-nexus-6-and.html" rel="nofollow">mipmap</a> before going through <code>mipmap</code> practically to understand its concept over <code>drawable</code>.</p>
  
  <p>What i've faced is, </p>
  
  <ol>
  <li>While working with <code>mipmap</code> <code>layout-preview</code> is not correct, while using image from <code>mipmap</code> folder.</li>
  <li>Is mipmap only for <code>launcher icon</code> ? do i need to manually create all <code>drawable</code> folders(<code>drawable-hdpi</code>, <code>drawable-mdpi</code> etc.) for all other <code>View</code>'s (<code>Button</code>, <code>ImageView</code>, etc.) image? If so then why don't android studio is not creating all <code>drawable</code> folder after creating new project?  </li>
  </ol>
  
  <p>I've also searched this issue but failed to get any useful or relevant link. I don't know what's wrong with <code>mipmap</code> because it seems fine while run code only layout preview is not correct.</p>
  
  <p><strong>Update :</strong></p>
  
  <p>Currently for workaround i've used <code>mipmap</code> folder only for <code>launcher-icon</code> and for all other <code>Views</code> i've manually created <code>drawable-mdpi</code>, <code>drawable-hdpi</code> etc.
  to make <code>layout-preview</code> fine.</p>
  
  <p>Please help!</p>
