title: Android: create drop shadow from path
body: <p>is there a way to create a drop shadow given a drawable with a path like below:</p>
  
  <pre><code>&lt;vector xmlns:android="http://schemas.android.com/apk/res/android"
          android:width="24dp"
          android:height="24dp"
          android:viewportHeight="24.0"
          android:viewportWidth="24.0"&gt;
      &lt;path
          android:fillColor="#FFFFFF"
          android:pathData="M19,6.41L17.59,5 12,10.59 6.41,5 5,6.41 10.59,12 5,17.59 6.41,19 12,13.41 17.59,19 19,17.59 13.41,12z"/&gt;
  &lt;/vector&gt;
  </code></pre>
  
  <p>both xml and programmatically would be good. I tried to do a little reasearch but couldn't find anything.</p>
  
  <p>EDIT: ideally I'll need somenthing reusable with whatever vector. Something like:</p>
  
  <pre><code>&lt;layer-list xmlns:android="http://schemas.android.com/apk/res/android"&gt;
      &lt;item&gt;
          //magic happens
      &lt;/item&gt;
      &lt;item&gt;
          &lt;include&gt; my_vector &lt;/include&gt;
      &lt;/item&gt;
  &lt;/layer-list&gt;
  </code></pre>
  
  <p>again, even programattically it's fine, if not better</p>
