/**
* This class animates properties of a {@link android.graphics.drawable.VectorDrawable} with

* <li><h4>XML for the VectorDrawable containing properties to be animated</h4>
* <p>
- * Animations can be performed on both group and path attributes, which requires groups and paths to
- * have unique names in the same VectorDrawable. Groups and paths without animations do not need to
- * be named.
+ * Animations can be performed on the animatable attributes in
+ * {@link android.graphics.drawable.VectorDrawable}. These attributes will be animated by
+ * {@link android.animation.ObjectAnimator}. The ObjectAnimator's target can be the root element,
+ * a group element or a path element. The targeted elements need to be named uniquely within
+ * the same VectorDrawable. Elements without animation do not need to be named.

* Below is an example of a VectorDrawable defined in vectordrawable.xml. This VectorDrawable is
* referred to by its file name (not including file suffix) in the
* <li><h4>XML for AnimatedVectorDrawable</h4>
* <p>
* An AnimatedVectorDrawable element has a VectorDrawable attribute, and one or more target
- * element(s). The target elements can be the path or group to be animated. Each target element
- * contains a name attribute that references a property (of a path or a group) to animate, and an
- * animation attribute that points to an ObjectAnimator or an AnimatorSet.
+ * element(s). The target element can specify its target by android:name attribute, and link the
+ * target with the proper ObjectAnimator or AnimatorSet by android:animation attribute.
* </p>
* The following code sample defines an AnimatedVectorDrawable. Note that the names refer to the
* groups and paths in the <a href="#VDExample">VectorDrawable XML above</a>.
* merge the XML files from the previous examples into one XML file:
