Support for Gradient Fill Colors

[pjacobs]

I have the following Vector Drawable..

<vector xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:aapt="http://schemas.android.com/aapt"
    android:width="78dp"
    android:height="120dp"
    android:viewportWidth="78"
    android:viewportHeight="120">
  <path
      android:pathData="M8,111a31,9 0,1 0,62 0a31,9 0,1 0,-62 0z"
      android:fillColor="#000"
      android:fillAlpha=".08"
      android:fillType="evenOdd"/>
  <path
      android:name="fillColorPath"
      android:pathData="M39,109c24.667,-33.044 37,-56.377 37,-70C76,18.565 59.435,2 39,2S2,18.565 2,39c0,13.623 12.333,36.956 37,70zM39,54c7.732,0 14,-6.268 14,-14s-6.268,-14 -14,-14 -14,6.268 -14,14 6.268,14 14,14z"
      android:strokeLineJoin="round"
      android:strokeWidth="4"
      android:strokeColor="#FF50BEFF"
      android:fillType="evenOdd">
    <aapt:attr name="android:fillColor">
      <gradient 
          android:startY="39.25312"
          android:startX="39"
          android:endY="40.31242"
          android:endX="39"
          android:type="linear">
        <item android:offset="0" android:color="#FF50BEFF"/>
        <item android:offset="1" android:color="#FF4BAFFF"/>
      </gradient>
    </aapt:attr>
  </path>
</vector>

Unfortunately, since the fillColor is set to a gradient in the fillColorPath path, PathModel.getFillColor returns 0, which is incorrect. I'm gathering this is not supported?
