title: Change fill color on vector asset in Android Studio
body: <p>Android Studio now supports vector assets on 21+ and will generate pngs for lower versions at compile time.  I have a vector asset (from the Material Icons) that I want to change the fill color.  This works on 21+, but the generated pngs do not change color.  Is there a way to do this?</p>
  
  <pre><code>&lt;vector android:height="48dp" android:viewportHeight="24.0"
  android:viewportWidth="24.0" android:width="48dp" xmlns:android="http://schemas.android.com/apk/res/android"&gt;
  &lt;path android:fillColor="@color/primary" android:pathData="M9,16.17L4.83,12l-1.42,1.41L9,19 21,7l-1.41,-1.41z"/&gt;
  </code></pre>
