/**
- * AnimatedVectorDrawable can use ObjectAnimator and AnimatorSet to animate
- * the property of the VectorDrawable.
+ * This class uses {@link android.animation.ObjectAnimator} and
+ * {@link android.animation.AnimatorSet} to animate the properties of a
+ * {@link android.graphics.drawable.VectorDrawable} to create an animated drawable.
+ * <p>
+ * AnimatedVectorDrawable are normally defined as 3 separate XML files.
+ * </p>
+ * <p>
+ * First is the XML file for {@link android.graphics.drawable.VectorDrawable}.
+ * Note that we allow the animation happen on the group's attributes and path's
+ * attributes, which requires they are uniquely named in this xml file. Groups
+ * and paths without animations do not need names.
+ * </p>
+ * <li>Here is a simple VectorDrawable in this vectordrawable.xml file.
+ * <pre>
+ * <vector xmlns:android="http://schemas.android.com/apk/res/android" >
+ * <size
+ * android:height="64dp"
+ * android:width="64dp" />
+ * <viewport
+ * android:viewportHeight="600"
+ * android:viewportWidth="600" />
+ * <group
+ * android:name="rotationGroup"
+ * android:pivotX="300.0"
+ * android:pivotY="300.0"
+ * android:rotation="45.0" >
+ * <path
+ * android:name="v"
+ * android:fill="#000000"
+ * android:pathData="M300,70 l 0,-70 70,70 0,0 -70,70z" />
+ * </group>
+ * </vector>
+ * </pre></li>
+ * <p>
+ * Second is the AnimatedVectorDrawable's xml file, which defines the target
+ * VectorDrawable, the target paths and groups to animate, the properties of the
+ * path and group to animate and the animations defined as the ObjectAnimators
+ * or AnimatorSets.
+ * </p>
+ * <li>Here is a simple AnimatedVectorDrawable defined in this avd.xml file.
+ * Note how we use the names to refer to the groups and paths in the vectordrawable.xml.
+ * <pre>
+ * <animated-vector xmlns:android="http://schemas.android.com/apk/res/android"
+ * android:drawable="@drawable/vectordrawable" >
+ * <target
+ * android:name="rotationGroup"
+ * android:animation="@anim/rotation" />
+ * <target
+ * android:name="v"
+ * android:animation="@anim/path_morph" />
+ * </animated-vector>
+ * </pre></li>
+ * <p>
+ * Last is the Animator xml file, which is the same as a normal ObjectAnimator
+ * or AnimatorSet.
+ * To complete this example, here are the 2 animator files used in avd.xml:
+ * rotation.xml and path_morph.xml.
+ * </p>
+ * <li>Here is the rotation.xml, which will rotate the target group for 360 degrees.
+ * <pre>
+ * <objectAnimator
+ * android:duration="6000"
+ * android:propertyName="rotation"
+ * android:valueFrom="0"
+ * android:valueTo="360" />
+ * </pre></li>
+ * <li>Here is the path_morph.xml, which will morph the path from one shape to
+ * the other. Note that the paths must be compatible for morphing.
+ * In more details, the paths should have exact same length of commands , and
+ * exact same length of parameters for each commands.
+ * Note that the path string are better stored in strings.xml for reusing.
+ * <pre>
+ * <set xmlns:android="http://schemas.android.com/apk/res/android">
+ * <objectAnimator
+ * android:duration="3000"
+ * android:propertyName="pathData"
+ * android:valueFrom="M300,70 l 0,-70 70,70 0,0 -70,70z"
+ * android:valueTo="M300,70 l 0,-70 70,0 0,140 -70,0 z"
+ * android:valueType="pathType"/>
+ * </set>
+ * </pre></li>
